Why are there roaches in the refrigerator?

Cockroaches have their roots in tropical or subtropical areas. Before they came to your fridge, they had gotten used to warm favorable conditions. Therefore, the motor compartment of your refrigerator might seem like a hospitable environment to them.

Regardless of whether you keep your fridge in order, or it is somewhat cluttered, you can see a fridge cockroach nest. However, they prefer dark and humid areas with grime over sanitary ones.

Cockroaches can eat various things such as meat, candies, leather, and even wallpaper paste. They can even feed on other roaches. They leave excrements and saliva on the food, as well as a repulsive odor.

How can they enter your refrigerator?

There are several ways these pests can get into the refrigerator. Since you can fix some of them on your own, let’s view these entrance points:

  • Gaps in the door. Even if you close the door tightly each time you take food out of the fridge, insects still can get inside if the rubber seal is loose;
  • Cracks and crevices in the outer shell. Cockroaches can enter your fridge from its back or underside components if there is a minor opening.

The cold doesn’t scare these pests since they can survive the low temperatures. Their egg sacs can preserve for a couple of months at 68 degrees Fahrenheit.

How to get them out of there

Though you might think that leaving your refrigerator without food for some time can help you get rid of pests, alas, I have the bad news for you. Roaches can survive an entire month without food and a week without a single water drop. Thus it is essential to know the effective methods to eliminate them once and for all.

Here are more details on how you can turn your refrigerator into an unattractive place for cockroaches. I’ve compiled step-by-step instructions that will guide you on the way to the fridge without roaches.

Step 1: Inspect your fridge carefully

First, you should do a thorough visual inspection of your kitchen device and the areas that surround it. You might need to pull it out from against the wall and look underneath it: Roaches commonly hide there. If you find any cockroaches nearby, you should identify the enemy to understand which species you’re dealing with.

Step 2: Do thorough cleaning

This is when you need to apply certain efforts to ensure the refrigerator is completely “insectless.” Clean any food particles you see to prevent them from building up. If you find any egg cases on the refrigerator surface, you should remove and destroy them. This is the exact sign you deal not with an occasional guest but with an entire infestation.

Sanitize the inside of your fridge afterward. Ensure that the cleaner you apply doesn’t feature a strong scent and is food-grade. Don’t forget to empty the pan that serves as a collector for condensed water beneath your refrigerator.

Step 3: Seal the cracks

I advise you to inspect not only the refrigerator but the kitchen area and the entire house and look for any cracks larger than an ⅛ inch. If you find them, seal them with the proper caulking. Seal any gaps around the electrical outlets by applying caulk to them.

Step 4: Place sticky traps to catch roaches

If you want to use insecticides inside the fridge, it’s better to restrain yourself from doing it. It can significantly harm your health. I advise putting traps around the fridge to cope with the infestation. Their working principle is as follows: When roaches step on a sticky trap, they cannot escape. Alternatively, you can place cockroach repellents without toxins in the chosen spots.

Step 5: Check the traps daily

Monitor the traps you have put into strategic spots on a daily basis. Their sticky surface will immobilize roaches. Check the progress every day. You can remove the traps if you don’t find pests there any longer.

Nota bene: Avoid liquid pesticides

Optionally, you can replace glue traps with non-liquid pesticides. The reason to avoid any pesticides in the liquid form is that they can short out the motor of the device and damage the coils. If you don’t want to place traps around your house for some reason, you can use dust or bait instead.

If you choose insecticidal dust, apply it around the fridge and replace the powder daily. When this powder contacts a cockroach, it gradually wears away the insect exoskeleton. It will further attack its nervous system or deteriorate the ability to absorb water over the following two weeks.

Can roaches survive in the freezer?

If you have a roach-infested fridge, you might wonder whether these pests can penetrate your freeze and prosper there. Luckily, roaches don’t survive more than 24 hours in a freezer. Sub-freezing temperatures kill their cold-blooded bodies after a day of exposure.

Can I spray the Raid under the fridge?

I would rather turn to other low-risk control strategies when it comes to food storage spots. Any spray insecticide you apply in the house disperses in the air, and you breathe it in. Thus using the aerosol under the fridge is potentially harmful. I advise glue traps, baits, and dust-form solutions.
