What Attracts Cockroaches Into a Home or Kitchen

Why cockroaches move in

Cockroaches are not fussy. They need somewhere warm, somewhere damp and a steady supply of almost any food, and a busy kitchen can offer all three. They are mostly active at night and spend the day tucked into narrow gaps, so by the time you see one in daylight there may already be a good number hiding nearby.

They can arrive in boxes, bags, second-hand appliances or deliveries, or move between connected properties through shared walls and service pipes.

Some species prefer the warmth of a heated kitchen, while others favour damp cellars, drains and basements. Whichever type is involved, the same basics apply: take away easy food and water, close off the gaps they use, and deal with any population promptly before it spreads.

Signs of cockroaches

Because they hide so well, the evidence often shows before the insects do. Check behind appliances, under sinks and inside cupboards where it is warm and dark.

Live insects running when you switch a light on at night
Small dark droppings that look like grains of pepper or coffee grounds
A stale, musty smell that lingers in cupboards or behind units
Pale, empty skins left behind as young cockroaches grow
Brown egg cases tucked into corners or behind appliances

What attracts them

Food is the obvious draw, but crumbs and grease that build up behind cookers and under fridges matter just as much as an open packet. Pet food left down overnight and full rubbish bags are also popular.

Moisture is just as important as food, and cockroaches will come for a dripping tap, a leaking pipe or a damp cupboard base. Warmth from boilers, fridges and hot water pipes keeps them comfortable through the colder months.

Cardboard, paper bags and old newspapers are also appealing, because they provide hiding places and the glue and starch can be food. Regular clear-outs of boxes and packaging in kitchens, stores and utility rooms help considerably.

Where Devon properties are at risk

Restaurants, takeaways, guest houses and holiday lets in busy coastal towns tend to have heavy kitchen use and frequent deliveries, which makes them more exposed than a quiet family home. Older buildings with hidden voids and many service routes give cockroaches plenty of places to travel unseen.

Homes are not immune, though, and a single infested item brought in can start a problem in any property.

Properties with shared drains, shared walls or a neighbouring food outlet can see activity move across from next door. If you suspect that is happening, let us know, as it affects how treatment is planned.

What you can do yourself

Good housekeeping makes a property much less welcoming. Focus on removing food, water and hiding places, and keep a close watch for new signs.

A torch and a few minutes each month is all you need to check under the sink, behind the fridge and inside cupboards. Keep a note of what you find and when, because it helps us understand how active the problem is.

Clean behind and under appliances regularly, including grease build-up
Store all food, including pet food, in sealed containers
Fix dripping taps and leaking pipes promptly
Empty bins daily and wash them out from time to time
Reduce clutter such as stacked cardboard, where they like to hide

What not to do, and when to call us

Over-the-counter sprays often scatter cockroaches deeper into the building rather than removing them, and they rarely reach eggs or the insects hiding inside walls. Using a lot of product in a food area is also unwise.

If you see live cockroaches, droppings or egg cases, call us. Cockroaches can carry germs onto food and surfaces, and a proper treatment usually involves identifying the species, finding the harbourage and following up to check it has worked.

Preventing a return

After treatment, keep up the habits that make your kitchen less attractive. Seal gaps around pipes, skirting boards and cupboards, check deliveries and second-hand items before bringing them in, and keep an eye on damp areas.

In a business, a written cleaning routine and regular staff checks make a real difference, and our team can advise on monitoring so that any returning activity is spotted early.

Frequently asked questions

Does seeing one cockroach mean I have an infestation?

Not always, as a single insect can arrive on a bag or box. Since cockroaches mostly come out at night, though, one seen by day is worth taking seriously. Check for droppings, egg cases and a musty smell, and call us if you find any of these.

Are cockroaches a sign of a dirty home?

No. Clean homes can get cockroaches too, because they travel in on deliveries or through shared walls. Dirt and spilt food make a property more attractive and help numbers grow, but cleanliness alone does not mean they will always stay away.

Can cockroaches spread illness?

They can pick up germs from drains and waste and carry them over food, utensils and worktops, which is why food businesses take them so seriously. Throw away food they may have touched, clean surfaces thoroughly and arrange professional treatment as soon as you can.

Why do they keep coming back after I spray?

Sprays usually only kill the insects they touch, while eggs and hidden adults survive in cracks and voids. The survivors then rebuild the population. Lasting control normally needs the right treatment placed where they shelter, followed by checks that confirm the problem has cleared.
