How to Get Roaches Out of Your Walls

Use Gel Baits Near Entry Points

Place gel baits near outlets, baseboards, & cracks in the wall. Roaches will consume the bait and return to their hiding spot, where they’ll die and potentially infect others through contact.

Tip – Don’t block the entry points until after treatment. You want them to take the bait back into the wall voids.

Apply Insecticidal Dust

Products like boric acid or diatomaceous earth can be applied inside wall voids.

• Remove outlet covers and lightly dust inside the wall cavity.

• Use a hand duster to ensure even application.

These substances stick to roaches and damage their exoskeletons, eventually killing them.

Use Insect Growth Regulators (IGRs)

IGRs stop roaches from reaching maturity or reproducing. Combine them with other treatments for more effective long-term results.

• Spray or place IGR stations near problem areas.

• Great for long-term infestations inside walls and hidden areas.

Seal Entry Points (After Treatment)

Once you’re confident the infestation is under control…

• Seal cracks in walls with caulk or foam insulation.

• Cover openings around pipes, electrical boxes, and vents.

• Install outlet sealers or covers to block access.

This prevents new roaches from moving in and forces survivors into the open where they’re easier to eliminate.

Call a Professional Exterminator

If DIY methods don’t work or the infestation is extensive, a licensed pest control professional can…

• Use advanced equipment to treat wall voids

• Apply stronger chemicals safely

• Set up a comprehensive treatment and prevention plan

Preventing Roaches from Returning

Once you’ve cleared out the walls, prevention is key.

Here’s how to keep them from coming back…

• Keep your kitchen and bathroom clean and dry.

• Store food in airtight containers.

• Take out the trash regularly.

• Fix any water leaks promptly.

• Reduce clutter to eliminate hiding places.

Getting roaches out of your walls may take time, but it’s entirely possible with the right combination of baits, dusts, & sealing.
