Why do large cockroaches come out of floor drains in hot weather?
Large cockroaches, usually American cockroaches, leave drains when sewers get hot, dry or crowded and they search for water, food and cooler air.
Dry floor traps are open doors. Pour water into unused drains regularly, fit proper drain covers and get the drainage area treated.
How do I get rid of German cockroaches in kitchen cabinets fast?
Use gel bait inside the cabinets, not spray, and treat the cracks and hinges where they hide.
Spraying scatters them and makes the problem worse. Empty the cabinets, remove cardboard and fix leaks. You may see a drop within days, but full control often takes a follow-up visit.
Do DIY cockroach sprays kill the whole nest?
No. They kill the cockroaches they touch, not the population hiding in walls, appliances and egg cases.
Repellent sprays can push roaches deeper and make professional bait work less well. Spray feels like action, but it is often just noise.
Why do I keep seeing cockroaches after cleaning my kitchen?
Because clean is not the same as sealed. Cockroaches live in wall voids and behind appliances, and come up through drains.
Cleaning only removes surface food. Check for leaks under the sink, food behind the fridge, cardboard boxes and shared walls with neighbours. Treat the source, not just the surface.
