Enoz Roach Away boric acid powder comes in a two-pack of 16-ounce bags, designed for indoor use. The formula is odorless and non-staining, making it suitable for living areas. Upon application, roaches that walk through treated areas are exed and ingest the powder as they groom themselves, leading to kill-off. This product supports a versatile pest management approach—particularly behind appliances, along baseboards, under sinks, and in cabinets—where roaches commonly travel. It is a practical option for households seeking a straightforward, minimal-odor solution with broad interior coverage.

The product covers strategic locations in kitchens and utility rooms, applying under and behind appliances, sinks, and other fixtures. Its targeted approach supports ongoing control, reducing roach activity by creating treated zones where roaches commonly traverse. The powder is suitable for multi-room usage and is designed to fit into routine maintenance plans for households facing persistent roach problems.
Terro T530 Roach Bait Powder Plus Applicator
Terro T530 combines a roach bait powder with an applicator designed to place bait directly into cracks and crevices. The product targets cockroaches and other pests, including ants, earwigs, and silverfish. The 360-degree nozzle facilitates precise placement, enabling targeted action in problem areas such as behind appliances, along baseboards, and inside cabinets. Bait powders can be a complementary strategy to contact-kill powders, offering a sustained reduction in roach populations by attracting and eradicating nest-adjacent pests.
Buying Guide: Key Purchase Considerations
- Active ingredient and pest target: Most white powders rely on boric acid or a similar inert powder. Consider whether you need broad-spectrum control (roaches, ants, silverfish) or a product focused on roaches alone.
- Application method: Puffers and dusters can simplify application in tight spaces. Applications behind appliances, under sinks, along baseboards, and inside cabinets are common and effective.
- Odor and staining: Odorless and non-staining formulas are typically preferable for homes with sensitivities or minimal aesthetic impact.
- Dry storage and durability: Powdered products perform best when kept dry. Inspect storage conditions and reapply as needed after moisture exposure.
- Longevity and maintenance: Long-lasting powders provide ongoing control between treatments, but frequent reapplication may be necessary in high-traffic areas or during active infestations.
- Safety considerations: Follow label directions, keep out of reach of children and pets, and wear protective gear (gloves, mask) when applying in confined spaces.
- Combination strategies: Some products include bait or lures, which can enhance early control. Using a combination of contact-kill powders and bait powders can improve results in mixed pest scenarios.
- Coverage area: Check the container size to estimate how many rooms can be treated. Larger bags often offer better value for ongoing household use.
- Resistance management: Rotate between different formulations or active ingredients to reduce the risk of pests developing resistance over time.
