How to Remove Cockroaches Permanently from Your Kitchen

Why spray treatments fail

Aerosol sprays kill the cockroaches you see — typically 5–10% of the colony. The other 90% sit behind your modular kitchen panels, inside cabinet hinges and under the sink, breeding. Most spray treatments make the problem worse because the colony scatters into rooms it wasn't previously occupying.

How professional gel-baiting works

We use a fipronil or indoxacarb gel applied as tiny dots (0.03g each) at 60–80 specific locations — hinge corners, behind electrical sockets, inside drawer rails. A foraging roach eats the bait, returns to the harborage, and dies. Other roaches feed on the carcass, frass and vomit — passing the active ingredient through the colony.

This 'horizontal transfer' is why a properly applied gel treatment can collapse a German cockroach population in 7–14 days with zero spray and zero odour. Kitchens stay usable the same day.

What you have to do for it to work

Do NOT clean the gel dots for 21 days — they're working. Do NOT spray Hit or Mortein anywhere in the kitchen; it repels roaches away from the bait. Wipe surfaces with plain water rather than disinfectant on the bait days. Most failed gel treatments fail because the homeowner sprayed insecticide on top of the bait.
