More Details on Our Top Picks
HARRIS Diatomaceous Earth Food Grade, 8 oz with Easy Application Puffer Tip
This small, food-grade diatomaceous earth from Harris is ideal for those seeking a safe, organic pest control option. Its 100% freshwater source and OMRI listing make it especially appealing for organic gardeners, and the puffer tip ensures targeted application in cracks and crevices. Compared to larger bulk options like the Harris 5lb, this 8 oz container is perfect for spot treatments but less suited for extensive infestations. Its main tradeoff is the limited quantity, which could require multiple purchases for larger areas. Still, its safe profile makes it a top choice for families with children or pets around gardening spaces.
Pros:- Made from 100% food-grade, chemical-free freshwater diatomaceous earth
- OMRI Listed for organic farming and gardening
- Includes an easy-to-use puffer tip for targeted application
Cons:- Limited to small quantities, requiring multiple purchases for large areas
- Requires careful handling to avoid inhalation
Best for: Organic gardeners or homeowners needing small, precise pest treatments around children and pets
Not ideal for: Large-scale infestations or commercial use where higher volume is needed
- Weight:8 Ounce
- Material:Food-grade freshwater diatomaceous earth
- Certifications:OMRI Listed for Organic Use
- Country of Origin:USA
Our verdict“This product suits organic gardeners who need precise, safe pest control in small areas.”
Harris 8 oz Diatomaceous Earth Crawling Insect Killer
This Harris product offers a broad-spectrum solution for crawling insects, functioning effectively both indoors and outdoors. Its powder form with a built-in puffer tip allows for targeted application, making it comparable to the more chemical-free Harris 8 oz Food Grade. Unlike the food-grade version, this is marketed as a pest killer, emphasizing immediate insect control. The main tradeoff is that it relies on dry conditions to remain effective, meaning it may need reapplication after rain or high humidity. It’s a solid choice for homeowners who want a quick, natural approach without sacrificing versatility, but it’s less suitable for very humid environments or large infestations requiring frequent reapplication.
Pros:- Effective against a wide range of crawling insects
- Non-toxic and pet-friendly when used properly
- Easy to apply with a built-in puffer tip for targeted control
Cons:- Requires dry conditions to remain effective
- May need repeated applications for severe infestations
Best for: Homeowners needing a versatile, effective dust for indoor and outdoor crawling insect control
Not ideal for: Areas prone to moisture or outdoor spaces with frequent rain where the powder might clump or wash away
- Weight:8 oz
- Application:Indoor & outdoor
- Ingredients:100% diatomaceous earth
- EPA Registration:No. 3-18
Our verdict“This product is best for those seeking a quick, versatile natural control for outdoor and indoor crawling pests.”
Diatomaceous Earth Food Grade and Peppermint Oil Insect Killer, Natural Crawling Pest Control for Home Garden, 1 lb
This blend of food-grade diatomaceous earth and peppermint oil offers a natural, chemical-free solution targeting multiple crawling pests like ants, roaches, and fleas. It’s particularly appealing for those who prefer a scented barrier, as the peppermint acts as a natural repellent. Compared to pure diatomaceous earth products like Harris 1 oz, this formulation provides added pest-repelling properties. However, its effectiveness may diminish over time, especially in persistent infestations, and the peppermint scent might be too strong for sensitive individuals. This makes it an excellent choice for garden areas or indoor spaces where scent and natural ingredients are priorities.
Pros:- Contains natural peppermint oil for added pest repelling
- Safe for indoor and outdoor use
- Effective against a variety of crawling insects
Cons:- May require multiple applications for persistent pests
- Less effective against flying insects
- Peppermint scent may be overpowering for some
Best for: Homeowners seeking a natural, scented pest control solution for indoor and outdoor use
Not ideal for: Users requiring a fast-acting or long-lasting solution against heavy or persistent pests
- Unit Count:16 Ounce
- UPC:740625757674
- Model Number:DE-01
- Best Sellers Rank:#2,216 in Patio, Lawn & Garden
- Customer Reviews:4.7/5
Our verdict“This product is ideal for those wanting a natural, scented barrier for moderate pest control in gardens or homes.”
Harris Diatomaceous Earth Food Grade, 5lb with Powder Duster, OMRI Listed for Organic Use
This 5-pound bag from Harris combines a generous quantity of food-grade diatomaceous earth with a handy powder duster, making it suitable for larger outdoor or garden applications. Its OMRI listing guarantees suitability for organic use, and the included duster allows for controlled, even application. Compared to smaller containers like the 8 oz, this bulk option is better suited for extensive pest management, though it requires more careful handling due to the fine powder, which can pose inhalation risks. It’s a practical choice for organic farms or large gardens but less convenient for small-scale or indoor use due to bulk and dusting considerations.
Pros:- OMRI Listed for organic use
- Includes a powder duster for controlled application
- Made from 100% natural, chemical-free freshwater diatomaceous earth
Cons:- Requires careful handling to prevent inhaling fine dust
- Limited to outdoor or specific applications as directed
Best for: Organic farmers or homeowners managing large outdoor pest issues
Not ideal for: Indoor spaces or small gardens where handling bulk powder is impractical
- Item Form:Powder
- Item Weight:5 pounds
- Volume:2.26 kg
- Certifications:OMRI Listed
- Source:Mined in Nevada, packaged in Georgia
Our verdict“This bulk diatomaceous earth is best for large outdoor pest control in organic settings where quantity and application control matter.”
Bonide Diatomaceous Earth Crawling Insect Killer, 1.3 lbs
Bonide’s diatomaceous earth offers a reliable, fast-acting insecticide solution for a variety of crawling pests. Its 1.3-pound size makes it easy to apply as a dust or slurry, suitable for both indoor and outdoor use, including on crops and around livestock. Compared with Harris’s smaller 8 oz options, Bonide’s larger size provides more coverage, though it still requires multiple applications for persistent pests. Its effectiveness within 48 hours makes it attractive for urgent pest issues, but the dust application can be messy, and reapplication is often needed to maintain control over time.
Pros:- Effective against a wide range of crawling insects
- Fast-acting, kills within 48 hours
- Suitable for indoor, outdoor, crops, and livestock use
Cons:- May require multiple applications for ongoing infestations
- Dust application can be messy
Best for: Homeowners and farmers needing quick, versatile pest control with larger coverage
Not ideal for: Indoor spaces where dust mess is a concern or for those seeking a chemical-free application
- Unit Count:20.8 Ounce
- UPC:037321001201
- Model Number:120
- Part Number:BND120
- Item Type:Diatomaceous Earth Dust
Our verdict“This product suits users who need a fast, broad-spectrum pest control solution for various environments.”
Harris Diatomaceous Earth Food Grade, 10 lb with Powder Duster
This Harris food-grade diatomaceous earth stands out for its generous 10-pound bag, making it ideal for large areas, and its inclusion of a powder duster facilitates precise application. Unlike smaller or less user-friendly options like the Harris 8 oz Diatomaceous Earth Crawling Insect Killer, this product offers a more practical solution for sustained pest control, especially in outdoor or extensive indoor spaces. Its OMRI listing confirms it’s suitable for organic gardening, and its sourced-in-USA status supports local economies. The main tradeoff involves the need for careful handling to prevent inhalation of fine powder, which can be an issue for users unfamiliar with dust products. Also, while effective, reapplications may be necessary for ongoing pest management, especially in areas with high pest pressure. Compared with the Bonide 5 lb or 1.3 lb options, this 10 lb bag provides better value for larger projects but may be overkill for small, occasional needs.
Pros:- Large 10-pound bag offers economical coverage for extensive use
- Includes a powder duster for targeted, easy application
- Made from 100% freshwater food-grade diatomaceous earth with no additives
- OMRI Listed for organic use, safe around children and pets when used properly
Cons:- Requires careful handling to avoid inhaling fine dust particles
- Limited specific information on pest control effectiveness in the product description
- Reapplication needed for persistent pests or ongoing infestations
Best for: Large households or farms seeking a cost-effective, organic pest control solution with extended coverage
Not ideal for: Individuals needing a small, quick application or who are sensitive to dust inhalation risks
- Material:Food-grade freshwater diatomaceous earth
- Weight:10 pounds
- Container Type:Bag
- Item Form:Powder
- Assay of Chemical(s):100%
- Molecular Weight:60.8
Our verdict“This pick makes the most sense for users needing a large, organic, and versatile diatomaceous earth supply for extensive pest management.”
Garden Safe Crawling Insect Killer with Diatomaceous Earth, 4 Lb
Compared with the Harris 10 lb option, the Garden Safe Crawling Insect Killer is designed specifically for outdoor environments, making it a practical choice for garden pest control. Its effectiveness against pests like ants, beetles, and fleas depends on direct contact, similar to the Safer Brand powder, but it’s easier to apply on soil, plants, and outdoor surfaces. It’s ideal for organic gardeners seeking a natural pest solution without synthetic chemicals, yet the need for repeated applications can be a drawback if pests are persistent or weather conditions wash away the dust. Since it’s limited to outdoor use, it’s not suitable for indoor pest control. The smaller 4 lb size makes it manageable for targeted outdoor areas but less suitable for large-scale or indoor pest issues, where the Harris 10 lb might be more convenient.
Pros:- Effective against a variety of outdoor crawling pests
- Suitable for organic gardening and environmentally friendly pest control
- Easy to apply directly to soil and plant surfaces
- Designed specifically for outdoor pest management
Cons:- Requires direct contact to kill pests, limiting residual effect
- Limited to outdoor use, so not useful for indoor infestations
- May need multiple applications for persistent or heavy pest pressure
Best for: Home gardeners wanting an organic, outdoor pest control method to protect plants and soil
Not ideal for: People seeking indoor pest control or quick knockdown of heavy infestations
- Brand:Garden Safe
- Unit Count:4 pounds
- UPC:072845932099
- Item Type:Insect Killer
- Model Number:93186
- Best Sellers Rank:#366 in Patio, Lawn & Garden
Our verdict“This product makes the most sense for organic gardeners focusing on outdoor pest control with minimal chemical impact.”
Safer Brand Diatomaceous Earth Powder Ant, Bed Bug & Insect Killer, 7 Ounces
The Safer Brand diatomaceous earth powder offers a handy 7-ounce size, making it a good choice for targeted indoor pest control of ants, bed bugs, and other crawling insects. Its effectiveness depends on direct contact, similar to the Garden Safe product, but it’s designed for both indoor and outdoor use, providing flexibility. Compared with larger, bulk options like the Harris 10 lb, it’s better suited for small, specific areas, reducing waste and mess. Its OMRI listing confirms safety for organic use, yet the 48-hour kill time might be slow for urgent infestations. Its compact size means less hassle for occasional or spot treatments but less economical for large infestations requiring extensive coverage.
Pros:- Effective against a variety of crawling pests
- Safe for indoor use and OMRI Listed for organic gardening
- Compact size ideal for targeted applications
- Works within 48 hours for pest dehydration
Cons:- Slow pest kill time compared to chemical options
- Requires direct contact for effectiveness
- Limited coverage area due to small size
Best for: Homeowners needing a small, effective solution for indoor pest issues or occasional outdoor use
Not ideal for: Users with large infestations or those seeking long-term residual control over extensive areas
- Weight:7 ounces
- Active Ingredient:Diatomaceous earth (77.69%)
- Application:Indoor and outdoor use
- Certifications:OMRI Listed
Our verdict“This product makes the most sense for small-scale, indoor pest control where precision and organic safety are priorities.”
Diatomaceous Earth Food Grade Powder with Peppermint – Pest Control for Bed Bugs, Roaches, Ants, Fleas – 1 lb
This 1-pound version combines diatomaceous earth with peppermint oil, offering both physical pest control and a natural repellent—an advantage over plain DE powders like the Harris or Safer Brand options. Its dual-action approach makes it more effective against persistent pests like bed bugs and roaches, especially in dry conditions, and the peppermint scent can deter future invasions. However, the smaller 1 lb size and reliance on physical contact mean reapplication is often necessary, especially after rain or cleaning, similar to other powders but with the added scent benefit. It’s ideal for indoor use or small outdoor areas, but larger infestations may require more extensive application or multiple treatments.
Pros:- Provides both physical pest control and a natural repellent effect
- Safe for families, pets, and gardens when used as directed
- Easy to apply and quick to act within 24-48 hours
- Natural peppermint scent adds a pest-deterring element
Cons:- Small 1 lb size limits total coverage area
- Effective only in dry conditions, requiring reapplication after rain or cleaning
- Multiple applications may be necessary for stubborn pests
Best for: Homeowners seeking a natural, dual-action pest control solution for small indoor or outdoor spaces
Not ideal for: Users facing large, persistent infestations or seeking long-lasting residual control without reapplication
- Weight:1 lb
- Ingredients:Food-grade diatomaceous earth, Peppermint oil
- Application:Indoor & outdoor use
- Safety:Family & pet safe when used as directed
Our verdict“This product best suits users wanting a natural, dual-action pest deterrent for small indoor or outdoor spaces with quick results.”
Diatomaceous Earth Food Grade & Peppermint Powder for Crawling Insect and Pest Control – 1 lb
Similar in size and purpose to the previous peppermint-infused powder, this product combines food-grade diatomaceous earth with peppermint oil to create a versatile barrier against a wide range of crawling insects. Unlike the Garden Safe outdoor formula, this is designed for both indoor and outdoor use, providing a flexible solution for organic pest management. Its effectiveness depends on proper application, just like the Safer Brand powder, but it offers the added benefit of scent-based deterrence. The need for reapplication after rain or cleaning is a common tradeoff, and its physical mode of action means it’s less suited for large infestations requiring chemical or residual treatments. The 1 lb size makes it easy to handle and store, ideal for targeted or occasional use.
Pros:- Effective against a broad spectrum of crawling pests
- Safe for use around children and pets
- Suitable for indoor, outdoor, and organic gardening applications
- Provides a natural barrier with peppermint scent
Cons:- Requires proper application to be effective
- Reapplication needed after rain or cleaning
- Physical mode of action may require multiple treatments for stubborn pests
Best for: Organic gardeners and homeowners seeking a safe, multi-purpose pest barrier for indoor or outdoor use
Not ideal for: Large infestations or users needing long-lasting residual control without frequent reapplication
- Weight:1 lb
- Ingredients:Diatomaceous earth, peppermint oil
- Standards:Food-grade
- Application:Indoor and outdoor
Our verdict“This product suits organic users who want a flexible, dual-purpose pest barrier for small to medium areas indoors or outdoors.”
Bonide Diatomaceous Earth Crawling Insect Killer, 5 lbs
This Bonide Diatomaceous Earth stands out for its broad insect targeting ability, working effectively against ants, cockroaches, fleas, and bedbugs both indoors and outdoors. It delivers results within 48 hours via contact or ingestion, making it a reliable all-rounder. Compared with the Harris 8oz pack, its larger quantity makes it a better value for continuous use, though it requires thorough coverage to avoid missed spots. Its natural, chemical-free composition ensures safety around crops and livestock when used properly, appealing to eco-conscious users. The main tradeoff is that multiple applications may be necessary for persistent pests, and the dust can be messy indoors. Its effectiveness hinges on correct application, which can be labor-intensive. Best for homeowners seeking an effective, natural pest solution with wide insect coverage.
Pros:- Effective against a wide range of crawling insects
- Works within 48 hours via contact or ingestion
- Safe for crops and livestock when used properly
- Natural ingredients and chemical-free

Our verdict“This pick makes the most sense for those needing a versatile, natural insect killer suitable for both indoor and outdoor use.”
Diatomaceous Earth Food Grade – 10lb, Organic & All-Natural Powder
This 10-pound bag of food-grade diatomaceous earth excels in organic gardening and soil conditioning, delivering a pure, all-natural product that’s safe for humans and pets. Its OMRI listing confirms suitability for organic gardening, making it a popular choice over the Harris 8oz options for larger applications. While it’s versatile for pest control, its primary strength lies in soil health and organic pest management, not quick knockouts of severe infestations. The silica content requires careful handling to avoid irritation. Compared with the Harris 8oz pack, its bulk offers better long-term value but demands more space and storage. Its organic certification makes it ideal for eco-minded users, though limited to garden and soil applications. Best for organic gardeners and soil enthusiasts seeking chemical-free pest control and soil improvement.
Pros:- OMRI Listed for organic certification
- Pure, natural, and chemical-free
- Versatile for gardening, soil, and pest control
- Safe for humans and pets when handled properly
Cons:- Limited to organic gardening applications
- Requires careful handling due to silica content
- Bulk size may be cumbersome for small-scale use
Best for: Organic gardeners and soil conditioners wanting a large, chemical-free pest solution
Not ideal for: Users needing quick pest eradication or indoor pest control without soil application
- Weight:10 lbs
- Certification:OMRI Listed
- Ingredients:Pure freshwater diatomaceous earth
- Suitable for:Organic gardening, soil conditioning, pest control
- Allergen Info:Vegan, keto, gluten-free
Our verdict“This product suits those prioritizing organic integrity and large quantity for gardening and pest management.”
Harris Diatomaceous Earth Crawling Insect Killer, 8oz (2 Pack)
This Harris 8oz dual pack offers a convenient, small-scale solution ideal for targeted pest issues around the home. Its non-toxic, pet-friendly formula makes it safer than chemical sprays, especially when using the built-in puffer tip for precise application. Compared with larger, bulk options like the Bonide 5 lb, this pack is perfect for small infestations or occasional touch-ups. Its physical mode of action—dehydration—means results may take time, especially with heavy or resistant infestations. It’s best used in dry conditions; heavy rain or moisture can diminish its effectiveness, requiring reapplication. Its compact size makes it easy to store and handle, but not suitable for large or persistent infestations. Best for pet owners needing a safe, precise, indoor pest control method.
Pros:- Effective against a broad spectrum of crawling insects
- Non-toxic and pet-friendly when used as directed
- Easy to apply with a built-in puffer tip
- Long-lasting when kept dry
Cons:- Requires dry conditions to maximize effectiveness

- Pack Count:2
- Material:Diatomaceous Earth
- Application:Indoor and outdoor pest control
- EPA Registration:No. 3-18
Our verdict“This product is ideal for small, targeted indoor pest issues where safety and precision are priorities.”
HARRIS Diatomaceous Earth Food Grade, 4lb with Powder Duster Included
This Harris 4lb food-grade diatomaceous earth combines purity with user-friendly features, including a powder duster for precise application. Its made from 100% ground freshwater diatomaceous earth and carries OMRI listing, making it safe for organic use and ideal for indoor pest control. Compared to larger bulk options, this smaller package is suited for homeowners with limited space or those wanting a convenient starter size. The inclusion of a powder duster simplifies application, reducing mess and waste. Its main limitation is the smaller size, which might mean frequent re-purchasing for ongoing infestations. Additionally, while safe and organic, it requires contact to be effective and may need multiple applications for persistent pests. A portion of profits supports a charitable cause, adding extra value. Best for organic enthusiasts who want easy application and support a good cause.
Pros:- Pure, additive-free, food-grade diatomaceous earth
- Includes a powder duster for easy application
- Supports a charitable cause with profits donated

Diatomaceous Earth 4 lb Organic OMRI Listed Bed Bug and Insect Killer
This 4 lb organic diatomaceous earth is formulated for comprehensive pest control, targeting bed bugs, ants, roaches, fleas, silverfish, and earwigs. Its OMRI listing assures organic safety and suitability for eco-conscious applications. The non-staining, odorless powder is ideal for indoor use, blending seamlessly into bedding, carpets, or cracks. Compared with larger bulk options, this smaller pack is perfect for targeted, indoor pest control, especially in sensitive environments. Its mode of action relies on contact, so it may take up to 48 hours to fully eliminate pests, and repeated applications are often necessary. Its organic certification and odorless nature make it a preferred choice for those avoiding chemical pesticides. However, it’s less suitable for outdoor use in moist conditions, which can diminish its efficacy. Best for organic households seeking a safe, multi-insect indoor pest solution.
Pros:- Effective against a wide range of crawling insects
- Organic and OMRI listed for safe use
- Non-staining and odorless
- Suitable for indoor environments
Cons:- Requires contact, so may need multiple applications

Not ideal for: Large infestations or outdoor use in damp conditions that require moisture-resistant solutions
- Weight:4 lbs
- Organic:Yes
- OMRI Listed:Yes

Our verdict“This product is well-suited for organic households needing a safe, multi-insect indoor solution with minimal mess.”
How We Picked
This selection process centered on evaluating each product’s purity, particle size, ease of application, and value for different user needs. We prioritized food-grade diatomaceous earth for safety and organic use, and considered whether the product offers convenient application tools like dusters. Price per weight was factored in to identify the best value options, while user reviews highlighted real-world effectiveness. Products were ranked based on a balance of performance, usability, and overall safety, making sure that each pick fills a distinct role for various buyers.Factors to Consider When Choosing Best Diatomaceous Earth Pest Control Products
Choosing the right diatomaceous earth pest control product involves more than just picking a brand. Consider the purity and grade, since food-grade options are safest around family members. Particle size matters — finer powders tend to cling better to pests, increasing effectiveness. Application method can make a big difference in coverage and ease of use, especially for larger areas or specific pests. Price per pound and packaging size influence value, particularly if you need ongoing pest control. Finally, look for added features like included dusters or pest-specific formulas to simplify application and target pests more effectively.Purity and Grade
The most critical factor is selecting food-grade diatomaceous earth, which is safe for indoor use and around pets. Lower-quality options may contain impurities or non-food-grade material, which could be unsafe or less effective. Always verify that the product is labeled as food-grade and OMRI-listed if organic certification matters to you. Higher purity powders tend to have finer particles, which adhere better to pests and provide quicker results.Particle Size and Texture
Finer powders, typically under 3 microns, are generally more effective because they stick to bugs and insects more easily. Coarser grades may be cheaper but tend to blow away or be less sticky, reducing effectiveness. When choosing, consider if the product is designed for indoor or outdoor use, as finer powders are more suitable for indoor pest control, while coarser grades can handle outdoor environments better.Application Method and Tools
Ease of application can significantly impact how thoroughly and evenly you can treat an area. Products with included dusters or applicators make the process less messy and more precise. Manual dusting can be time-consuming and uneven, especially in hard-to-reach spots. For larger spaces, a product with a built-in duster or easy-to-use shaker can save time and improve coverage.Value and Packaging Size
Larger packages often provide better per-pound value but require more storage space and a larger initial investment. Smaller sizes are more manageable for occasional use but tend to cost more per pound. Consider how much pest control you need and choose a package size that balances cost with practicality. Also, check if the product is available in resealable packaging to maintain freshness and prevent clumping.Additional Features and Pest-Specific Formulas
Some products include added ingredients like peppermint oil, which can help repel pests or make application more pleasant. Pest-specific formulas can target particular bugs such as bed bugs or ants more effectively. Application tools like powder dusters, spray bottles, or pre-measured packets simplify the process, especially for beginners. Evaluate whether these features match your pest problem and comfort level with application.Frequently Asked Questions
Is diatomaceous earth safe for use around pets and children?
Yes, food-grade diatomaceous earth is considered safe for use around pets and children when used as directed. It is non-toxic and organic, making it a popular choice for household pest control. However, it is still advisable to avoid inhaling the dust directly and to keep application areas clean to prevent excessive airborne particles. Proper application and storage help maintain safety and effectiveness, especially in homes with vulnerable family members.
How often should I reapply diatomaceous earth for pest control?
Reapplication frequency depends on the severity of the infestation and environmental conditions. In general, applying diatomaceous earth every 1-2 weeks is effective for ongoing pest management. After rain or heavy cleaning, reapplication is recommended outdoors or in damp areas where the powder may have been washed away. Regular checks and reapplication ensure pests remain controlled, especially in high-traffic or pest-prone zones.
Can diatomaceous earth be used outdoors, and which type is best?
Yes, diatomaceous earth can be used outdoors, but it’s important to choose a coarse, pest-specific grade designed for outdoor environments. Food-grade, fine powders are best suited for indoor use where safety is a priority. For outdoor use, a coarser grade provides better durability against weather and environmental factors. Always apply when dry and avoid application before rain to maintain efficacy.
Will diatomaceous earth harm beneficial insects like bees or ladybugs?
Diatomaceous earth primarily affects insects that crawl through it, including pests like ants and bed bugs. Beneficial insects that do not come into direct contact with the powder are usually unaffected. However, applying it directly on flowers or plants where pollinators visit can pose risks. Use it carefully around flowering plants and avoid broad, indiscriminate spraying to protect beneficial insect populations.
How do I apply diatomaceous earth for best results?
For optimal results, apply diatomaceous earth in dry conditions, using a duster or applicator that allows fine, even coverage. Focus on cracks, crevices, baseboards, and areas where pests are active. Avoid applying in windy conditions outdoors to prevent powder from blowing away. Reapply after cleaning, rain, or if the area becomes dusty or clogged, to maintain pest control effectiveness.
Conclusion
For those seeking the best overall performance and ease of use, HARRIS Diatomaceous Earth Food Grade remains the top choice, especially for indoor pest control.
