HARRIS Boric Acid Roach And Silverfish Killer Powder W/Lure, 32oz
This 32-ounce bag adds significant coverage for larger homes or persistent infestations. Like the smaller version, it uses boric acid to disrupt roach activity, with a long-lasting effect as long as kept dry. The package includes a powder duster with an extended straw to facilitate application in tight gaps, behind appliances, and along baseboards. The powder clings to roaches and is ingested during grooming, helping reduce reinfestation over time.
Key considerations:
– Higher volume for large spaces or recurring problems
– Duster enables precise application in hard-to-reach areas
– Maintains low odor and non-staining properties when used properly
Enoz Roach Away Boric Acid Powder (2 Pack, 16 oz Each)

The product’s odorless, non-staining formula is a benefit for homes with sensitive occupants or soft furnishings. It’s versatile for use behind appliances, along baseboards, and in cabinets to establish a protective barrier against infestations.
Highlights:
– High-purity boric acid formulation
– Odorless and non-staining
– Two-bag pack provides ample supply for multiple rooms

It serves as a barrier treatment under refrigerators, stoves, sinks, and other high-traffic areas where roaches travel. The powder is designed to kill cockroaches, ants, silverfish, palmetto bugs, and waterbugs by creating a difficult path for roaches to cross. The included applicator helps ensure even coverage and reduces mess during application.
Practical notes:
– Multi-pest effectiveness with a boric acid base
– Easy barrier application for kitchen and utility areas
– Broad distance coverage for mid-sized homes
Terro T530 Roach Bait Powder Plus Applicator
Terro T530 focuses on combination control with powder bait and an applicator to reach cracks and crevices. While not pure boric acid powder, it is highly effective at delivering a targeted dose of bait where roaches feed. The 360-degree nozzle aids placement into tight spaces, allowing for precise treatment around kitchens and bathrooms. It’s well-suited for homeowners seeking an integrated approach that combines powder-based barrier strategies with targeted bait stations.
Considerations include:
– Direct bait delivery for immediate roach exposure
– 360-degree applicator for full coverage in crevices
– Complementary to powder-based barrier treatments
Buying Guide: Key Purchase Considerations And Comparisons
When selecting a white powder for roaches, evaluate the following factors to ensure the option fits your home and infestation level:
- Active ingredient and target pests: Boric acid remains a cost-effective, low-toxicity option for roaches, silverfish, and some ants. Some products pair boric acid with attractants, increasing uptake by roaches.
- Volume and coverage: Larger bags (32 oz or more) are ideal for bigger homes or persistent infestations, while smaller packages suit smaller spaces or single rooms.
- Application method: Powder formulations with a puff applicator or duster facilitate distribution behind appliances and in narrow gaps. A nozzle or straw applicator helps reach hard-to-reach areas.
- Odor and staining: Most boric acid powders are odorless and non-staining when used as directed, which is important for homes with sensitive occupants or furnishings.
- Safety and usage: Follow label directions, keep out of reach of children and pets, and avoid inhaling the powder. Use in dry conditions to maximize efficacy.
- Combination strategies: Some products pair powder with bait or lure for a two-pronged approach—rapid knockdown and longer-term suppression.
- Reapplication and maintenance: For ongoing problems, periodic reapplication in problem areas helps prevent reinfestation, especially in kitchens, bathrooms, and utility rooms.
Bottom line: For many American homes facing roach challenges, boric acid powders offer an economical, relatively safe, and effective line of defense. The best choice depends on room size, infestation severity, and whether you prefer a simple powder barrier, a combination with bait, or a ready-to-use duster system for hard-to-reach spaces.
