What's in my kitchen cupboard?

Tiny beetles in the flour, flies around the fruit bowl, a line of ants on the worktop, or something that scuttles when you switch on the light. Answer five quick questions and we'll tell you what it probably is and how to clear it.

Your case

Common kitchen pests at a glance

Most kitchen pests fall into two groups: insects that arrive in food packets and live in your cupboards, and visitors that come in from outside or from neighbouring homes looking for food and warmth.

Bugs in flour, rice and cereal

Tiny beetles, weevils, moths and mites almost always arrive in an infested packet. The fix is a thorough clear-out: check every dry food in the cupboard, bin what's infested, vacuum the shelves and store food in airtight containers. Our pantry pests guide has the full checklist.

Something scuttling at night

Insects that scatter when you turn the light on are usually cockroaches or silverfish. Cockroaches are faster and bigger and live behind warm appliances. Silverfish wriggle and prefer damp spots. See our guides to cockroaches and silverfish.

Questions people ask

Are kitchen bugs a sign of a dirty kitchen?

Usually not. Most pantry pests arrive in shop-bought packets, and cockroaches and ants come in from outside or neighbouring homes.

Do I have to throw everything away?

Only food that's infested or in open packets. Sealed tins and jars are fine. Freeze anything you're unsure about for four days.

Can I use insect spray in the kitchen?

Keep sprays away from food and surfaces you prepare food on. Gel baits in cracks are safer and usually more effective for cockroaches and ants.
