Cockroach infestations are increasing as the climate becomes warmer. They can be treated effectively in various ways using chemicals and bait boxes.

Preventative measures include keeping all food stored away in sealed containers, using rubbish bins with a tight lid, frequent cleaning in the kitchen, and regular vacuuming. Any water leaks, such as dripping taps, should also be repaired. It is also helpful to seal off any entry points, such as holes around baseboards, in between kitchen cabinets, pipes, doors, and windows with some steel wool or copper mesh and some cement, putty or silicone caulk. Once a cockroach infestation occurs, chemical controls can help alleviate the problem.
