Cockroaches aren’t just gross. They’re smart, resilient, and they breed faster than you can squash them. Bug spray gives you instant satisfaction but you’re coating your kitchen in chemicals while more roaches pour in from behind the walls. The real fix is cutting off what keeps them alive.
1. Clean Obsessively
Roaches eat everything. Crumbs under the toaster. Grease splatter behind the stove. That weird sticky spot on the counter you’ve been ignoring. They’ll even eat cardboard and book bindings if they’re desperate enough.
Wipe down surfaces every night. Vacuum regularly. Don’t leave dishes in the sink overnight. Store food in sealed containers, not those flimsy boxes they came in. No food source, no reason to stay.
2. Fix Leaks Immediately
A dripping pipe is a roach oasis. They can survive weeks without food but only days without water. Fix leaky faucets, tighten pipe joints under sinks, and address anywhere moisture collects.
Check for condensation on pipes in cabinets and crawl spaces too. Even that thin film of water is enough to sustain a colony.
3. Use Boric Acid Bait
This is the heavy hitter. Mix 1 tablespoon of boric acid with 3 tablespoons of sugar and just enough water to form a paste. The sugar lures them in; the boric acid kills slowly enough that they carry it back to the nest before dying. The whole colony takes the hit, not just the ones you spotted.
Put thin smears on cardboard scraps behind the fridge, under the stove, in cabinet corners. Don’t pile it on. Keep it away from kids and pets. For a liquid version: 1 teaspoon boric acid, 8 teaspoons sugar, 1 cup (240 ml) warm water on cotton balls. Replace every few days until activity stops.
4. Kill the Ones You See
Smash them. Spray them with soapy water if you don’t want to touch them. Don’t let them scuttle away because you’ll deal with it later. Each roach you kill is one that won’t breed, and they breed aggressively.
5. Seal Entry Points
They’re squeezing in through gaps you didn’t know existed. Caulk around pipes, baseboards, window frames, and door gaps. Weatherstrip exterior doors. Pay special attention to the kitchen and bathroom, where the water is.
This won’t fix an existing infestation, but it stops the next wave from walking in behind the ones you just killed.
6. Call Pest Control
If you’re seeing roaches in daylight, you’ve got a serious problem. They’re nocturnal, so daytime sightings mean the hiding spots are full. A professional has stronger treatments and knows where roaches actually nest, not just where you think they do.
