Store food so nothing is available
Transfer opened dry goods into sealed containers rather than leaving them in packets. Wipe up crumbs and spills promptly, including inside cupboards, behind appliances and under sinks.
Deal with waste daily
Waste is a standing invitation. Use bins with lids, empty them at the end of the day, and keep the waste area outside away from walls and doors where possible.
Keep the space dry
Fix dripping taps and leaks, and dry out areas under sinks and behind equipment. Moisture is the single condition most often left unaddressed.
