1. Thoroughly Clean In & Around Each Appliance

As we mentioned previously, cockroaches gravitate towards dirty areas. Although your home may be clean, your appliances may tell a different story. The first thing you should do after spotting a cockroach in your appliances is to thoroughly clean the appliance. This includes the surface area but it also involves moving the appliance from its position to clean behind and underneath.

This can be quite a task if the appliance the cockroaches have chosen is something large such as a refrigerator, washing machine, or dishwasher so be sure to ask for help during this process! It is important to also clean inside the appliance. Remove any shelves, drawers, or other features as you are able. If you are cleaning the refrigerator, also be sure to empty the water tray and clean the freezer while you are at it.

Try to eliminate any source of excess moisture or crumbs to decrease the attractiveness of the appliance.

2. Don’t Leave Food or Trash Out Longer Than Necessary

Second, assess your kitchen habits. If you live alone or with one other person, you are likely not taking the trash out every day. Cockroaches are attracted to this as a primary source of sustenance. To eliminate excessive use of trash bags, consider switching to a smaller bag size, allowing you to take the trash outside at the end of each day.

Additionally, get in the habit of storing your food in sealed containers instead of letting snacks sit out on the countertop. After each meal, wipe the countertops with a gentle household cleaner to eliminate crumbs or drops of food that remain after your meal prep. By keeping a clean kitchen, you can minimize the potential of cockroaches taking over your kitchen appliances.

Signs You May Have Cockroaches in Your Appliances

For most people, a cockroach sighting is the first sign of their existence in your home. Sometimes the first sign of a cockroach you will see is a dead cockroach lying belly up on your floor! 

However, other signs may alert you of their presence long before you see one crawling across your countertops. One of the most obvious signs of a cockroach infestation is the dark droppings that they leave behind. These droppings look very similar to coffee grounds or pepper. When found in your kitchen, you may simply dust them off the countertop, asking your roommates to do a better job cleaning up after themselves.

It is important to identify and prevent cockroach droppings on your countertops as they contain pathogens and bacteria that can easily spread!

If you live in an area of high moisture, you may notice the smear marks that a cockroach will leave as they crawl along your walls or flooring. These marks are dark in color and irregularly shaped, often found on horizontal surfaces or near the floor.

There are other, less common signs you may notice. Some of these include shed skin, cockroach eggs, unusual musty odors, or even damage to your property.
