HARRIS Boric Acid Roach and Silverfish Killer Powder with Lure

This 16-ounce package combines boric acid with a formulated lure to attract roaches, palmetto bugs, water bugs, and silverfish. The product is designed for long-lasting efficacy as long as kept dry, and it offers fast-acting results—dispatched insects typically die within 72 hours of initial contact. An integrated puff/duster mechanism enables targeted application in hard-to-reach spaces, reducing the need to move heavy furniture or disturb clutter.
Key features include durable residual action, easy application, and a focus on common indoor invaders. The lure helps improve bait uptake in areas where roaches hide, such as behind appliances, under sinks, and inside cabinets. For households dealing with multiple pest species, this product provides a broad-spectrum approach without requiring multiple separate treatments.
Harris Boric Acid Roach and Silverfish Killer Powder with Duster (32oz)

This larger 32-ounce bag adds a powder duster with an extended straw to reach tight gaps and inner crevices. The extended delivery helps coat areas like pantry corners, under the refrigerator, and behind baseboards without heavy lifting. The product continues to deliver long-lasting kill potential as long as kept dry, with fast-acting contact death. This option suits larger homes or spaces where roaches persist despite initial treatments.
Consider this formulation when you need higher volume coverage and convenient application tools. The combination of long residual activity and a practical applicator makes it a solid choice for persistent infestations or multi-room treatments, especially in kitchens and utility spaces where moisture and warmth attract insects.
Harris Roach Tablets with Lure

These boric acid tablets combine 40% boric acid with a formulated lure designed to attract roaches. Packaged as 6-ounce tablets with a 2-pack option, they present a regulated, long-lasting approach that remains effective when kept dry. The EPA-registered formula provides a monitored exposure level suitable for homes seeking a controlled pest management strategy rather than broad, indiscriminate spraying.
Use tablets in discreet areas where roaches commonly congregate, such as near drains, behind stoves, and under sinks. The lure helps entice roaches into contact with the poison, and the dry conditions of most indoor environments support extended residual action. This option aligns well with integrated pest management plans that prioritize targeted, professional-grade solutions.
Enoz Roach Away Boric Acid Powder (2 Pack)

Enoz Roach Away boric acid powder comes in a two-pack, 16-ounce bag format designed for indoor use. The odorless, non-staining powder helps control roaches and other listed pests by clinging to their bodies as they traverse treated surfaces, ensuring ingestion during grooming. This formulation emphasizes a straightforward dusting approach in corners, behind appliances, and along baseboards.
The dual-bag setup supports ongoing treatment across multiple rooms, making it a practical option for homes with sprawling floor plans or where roaches travel between kitchens and living spaces. The product’s emphasis on indoor containment and user-friendly application is a fit for homeowners seeking a simple, repeatable routine.
JT Eaton Boric Acid Insecticidal Dust

JT Eaton’s boric acid insecticidal dust comes in a 25-pound resealable pail. This larger quantity suits professional applications or households with heavy infestation. The product is designed to be a simple, effective dust that targets roaches, ants, silverfish, and other labeled pests. The formula emphasizes long-lasting protection with a straightforward application method, suitable for cracks, crevices, and shelf edges where pests travel.
As a high-volume option, it is best used by homeowners who prefer a durable, low-odor powder that blends into interior spaces without attracting attention. The resealable container helps maintain product integrity between applications and supports ongoing maintenance programs in busy homes or small businesses.
Nisus Magnetic Roach Bait Paste Formula

Nisus’ magnetic bait paste uses food-grade ingredients designed to attract roaches while delivering boric acid in a palatable, long-lasting format. The paste remains soft and attractive longer than many other baits, making it suitable for long-term roach control. It’s particularly well-suited for crack-and-crevice treatment using a bait gun, enabling precise placement behind appliances, under sinks, and around drainage areas. The product supports maintenance programs in both homes and commercial settings and integrates with fecal-deposit dynamics to help control roach populations over time.
For kitchens, pantries, and utility rooms with repeated roach activity, this paste offers a steady intake mechanism. It is an option when a pest management plan calls for continuous, low-dose exposure rather than single-dose traps, reducing the likelihood of reinfestation through sustained exposure.
Hot Shot MaxAttrax Roach Killing Powder

Hot Shot MaxAttrax combines boric acid with a ready-to-use powder applicator, aimed at creating a barrier that roaches and other pests must cross. The product is designed for use in key indoor locations such as under refrigerators, stoves, sinks, dishwashers, and laundry or utility spaces. The easy applicator helps users deploy the powder precisely along baseboard lines, behind appliances, and in other tight spots where roaches travel. The formula is effective against a range of pests, including ants, silverfish, palmetto bugs, and waterbugs, providing a broad, practical solution for layered pest issues.
Whether addressing a mild or moderate infestation, this powder is a straightforward option for homeowners who want a quick, repeatable barrier treatment. Its emphasis on selective placement supports targeted, responsible use in living areas where children and pets may be present, as with all boric acid products.
Buying Guide: Key Purchase Considerations and Comparisons
When choosing a boric acid product for roaches, consider: formulation type (dust, powder, bait paste, or tablets), application method (duster, crack-and-crevice, or behind-appliance placement), and residual duration (short-term vs. long-lasting). For dry, well-ventilated spaces, powder-based products with a lure can attract roaches and deliver quicker kills, while non-odor formulations are preferable in sensitive living areas.
Other considerations include EPA registration and safety profiles, especially in households with children or pets. Bait pastes and tablets provide targeted exposure and can support long-term control when integrated with good sanitation practices. Dust formulations offer broad coverage but require careful application to minimize inhalation risk. For larger homes, larger-volume options or multi-pack sets help maintain ongoing control without frequent restocking.
Application tips include dusting in hidden crevices, behind and beneath appliances, along baseboards, and near drains or moisture sources. Always follow label directions, keep products dry as moisture reduces effectiveness, and combine chemical controls with non-chemical measures such as removing food sources, sealing entry points, and maintaining clean, dry spaces.
In choosing among these options, align your choice with infestation severity, space dimensions, and user comfort with different application tools (puffer bottles, dusters, or paste guns). For multi-room homes, a combination approach—dust in one area and paste or bait in another—can optimize coverage while minimizing exposure.
In sum, boric acid-based products offer a proven, cost-effective route to controlling roaches and other common pests in American homes. By selecting a formulation that matches your space, infestation level, and safety preferences, you can achieve lasting relief with consistent maintenance and proper application.
