Cockroaches can live in a hostile environment without water or food for a long period. Its possible to have cockroaches living in the cleanest of homes, and in such situations, they will take cover in the kitchen and more specifically in your dishwasher. Most homeowners get frustrated when they find cockroaches in their dishwasher since they are unsure of how to get rid of them. The dishwasher is a very delicate location, and it might be very difficult to get rid of cockroaches without contaminating the dishwasher with toxic chemicals. You could also eliminate roaches from your dishwasher using non-toxic methods, and they will disappear completely.
Clean your dishwasher
Proper sanitation will go a long way to preventing cockroaches from invading your dishwasher. First, you will need to pull out any dishes that are in the dishwasher and set them aside. Remove the rack at the bottom and examine the drain. Cockroaches are known to thrive in tight spaces and especially if the tight space means getting water and food. Get rid of any debris from your drain. Place a cup of white vinegar on the top rack, then run your dishwasher on the hottest cycle. Cockroaches are unable to stand extreme heat or cold. This process will sanitize the dishwasher as well as flush out any stragglers.
Get rid of the entry points
Once the dishwasher is sanitized, and all the roaches hiding within have been flushed, you need to take preventive measures to ensure that the cockroaches do not make a home of your dishwasher again. Inspect your dishwasher for cracks and open spaces and fill them with caulk. You can also apply a fine layer of boric acid that is invisible to the eye.
Get rid of any remaining cockroaches
You can effectively get rid of any remaining cockroaches by mixing one-part boric acid, two parts flour, two parts cocoa and sprinkling them around areas in your kitchen that you suspect have cockroach activity. Ensure that the mixture is sprinkled on your floorboards, plumbing and under your refrigerator. To keep roaches out of your newly cleaned dishwasher, make sure that there are none left anywhere in your kitchen.
Take preventive measures
Ensure that your dishwasher door is always shut at all times. Especially when there are dirty dishes waiting to be cleaned. Avoid leaving food on your kitchen countertops and surfaces. Make sure that you take your trash out daily. Also, regularly clean your dishwasher. A good rule of thumb is to have it cleaned once in two weeks; this will ensure there are no food scraps laying around. Sanitize your dishwasher every other weekend or as need be.
In case you notice cockroaches in your dishwasher, it is a wise idea to call your local pest control service to check it out. More often than not, the presence of cockroaches in dishwashers normally points out to a cockroach infestation. Getting a professional to help you deal with this problem will mean effectively get rid of your cockroach problem for good.
