Do Refrigerators Attract Roaches?

Cockroaches are found in many areas of the house. Some of them live in bathrooms while others in basements. But most cockroaches are found in the kitchen.

The kitchen provides sufficient food and shelter for roaches to survive, breed, and live a sheltered life.

Cockroach nests are commonly found behind the refrigerator. But these nests can also be found anywhere else around the kitchen.

The warmth from refrigerators can attract water. Food traces behind the fridge are also known to attract cockroaches. Most importantly, defrosting cycles that create humidity under the fridge attract American and German cockroaches.

It’s important to know how your refrigerator works to keep roaches out. This is especially true in the case of cockroaches.

Even more, you regularly need to clean behind the fridge if you want to keep roaches and other pests out.

Defrost cycles might attract roaches

While the refrigerator itself is not a target for cockroaches, it’s what it does that attracts them.

Defrost cycles may lead to refrigerators dripping water in a tray. This is where many cockroaches find a trace of humidity which they may or may not need, depending on their species.

American cockroaches and German cockroaches are attracted to the humidity created by defrosting refrigerators. Dripping water creates humidity and organic material buildup under the fridge which attracts cockroaches.

Common solutions

One of the easiest solutions is to clean behind and under the fridge frequently. Make sure to wipe out all excess water and organic material buildup under the fridge as these might be an area that’s not cleaned frequently with the rest of the house.

Cockroaches like the heat generated by refrigerators

Refrigerators generate heat to make cold air. Surplus heat needs to be eliminated and this happens in different ways depending on your brand of refrigerator.

New Samsung refrigerators give off heat through side panels. Cooling pipes are installed under these panels which manes heat is directed towards the left and right parts of the refrigerator.

Cockroaches may not climb these side parts of the refrigerator but they gather around the refrigerator to escape the cold temperatures they hate.

One of the best places for them to be as close as possible to the heat source of the refrigerator is its sides, as well as the space under the refrigerator since many sides of refrigerators, are blocked by cabinets and kitchen furniture.

High moisture behind refrigerators attracts roaches

High moisture exists behind the fridge to a small extent. This is still sufficient to attract cockroaches. Humidity is favored by poor ventilation behind the fridge as well as by defrosting cycles.

Common solutions for humidity issues behind the fridge

You can reduce the impact of humidity behind the fridge by taking it out from time to time for cleaning. Allowing a couple of inches between the back of the fridge and the wall may also help air currents limit humidity issues.

Any known humidity issues in the kitchen that aren’t related to the refrigerator are only going to make these aspects worse.

Dead insects and food traces behind the refrigerator attract roaches

People assume all cockroaches are the same and they eat the same thing. This is a false premise.

However, some cockroaches eat dead insects and even live insects which may also include members of their species.

Oriental cockroaches eat dead cockroaches or the body parts of dead cockroaches they can find behind the refrigerator. German cockroaches also eat dead cockroaches and dead insect parts they can find behind the fridge.

Warmth and humidity attract other insects under and behind the refrigerator which often brings in cockroaches.

Solutions against dead insects behind the refrigerator

As with all other solutions, it’s important to clean the space behind and under the fridge frequently. If you drop fruit or any type of food behind the refrigerator you should take the refrigerator out and not let it rot and attract insects and cockroaches.

Dark undisturbed habitats attract roaches

One of the main reasons cockroaches are attracted to refrigerators is because this area is dark, secluded, or safe. A safe space where they aren’t exposed to people or possible predators is crucial for cockroach nests.

This is the main reason they create a safe space behind the refrigerator. You might even find out cockroaches are among the species that live under the fridge whenever the space is perfectly clean just because they can crawl under it.

Are cockroaches attracted to noises?

Cockroaches hate loud sounds and noises such as slamming doors and windows. They get scared of the noise of closing the refrigerator door when they might crawl out from under the refrigerator.

Cockroaches are not attracted to noises as they prefer quiet undisturbed places. The noisier your refrigerator is the higher the chances of it keeping roaches away.

Do old refrigerators attract roaches?

Old refrigerators aren’t self-defrosting. They might still leak water due to condensation which means even old refrigerators can generate humidity cockroaches love and are attracted to.

Do new refrigerators attract roaches?

New refrigerators are mostly self-defrosting. This means they might leak water which creates humidity roaches like. There are high chances of finding cockroaches under a new refrigerator when this humidity and water buildup isn’t cleared.

Should you be worried about refrigerators in case of a cockroach infestation?

While cockroaches love space under or near refrigerators, they don’t get inside because of the refrigerator. They get inside because they can find crawling spaces in wall cracks or move indoors under doors where they find food.


Refrigerators are some of the favorite places of cockroaches in the kitchen. But refrigerators themselves aren’t sufficient to attract roaches which tend to invade homes for other reasons.

Refrigerators are only perceived as a problem appliance for cockroaches because they are difficult to get out for cleaning and because roaches hide under them. But then can hide under anything dark, warm, and humid just as well.
