The difference between the cockroaches you see outside and the ones breeding in your kitchen.
Not all cockroaches are the same
Small, light-brown cockroaches with two dark stripes behind the head are usually German cockroaches. They live and breed indoors, close to food and warmth. Large, reddish-brown cockroaches are often American or Australian cockroaches that live outside and in drains, and wander in.
Why sprays don’t fix it
Surface sprays kill the cockroaches you see, but most of the population is hidden in cracks, hinges and motors, and egg cases are protected from many sprays. A few weeks later, a new generation hatches.
What works
- Gel baits placed where cockroaches feed and shelter
- Insect growth regulators that stop young cockroaches maturing
- A follow-up visit for German cockroach infestations
- Cleaning behind and under appliances to remove grease and crumbs
Help keep them away
- Wipe benches and sweep floors every night
- Store food in sealed containers
- Fix dripping taps and leaks under sinks
- Seal gaps around pipes and behind cupboards
