Even the cleanest housekeeper occasionally finds insects and gnats, aka "bugs," in the kitchen. Generally, bugs are brought in with your groceries, in the bags or on produce. If you do not notice them right away, bugs can infest cereal, flour, dried goods and even the refrigerator. Since you should not use pesticides in the kitchen and around foods, it takes extra work to eradicate bugs, especially if they have infested the refrigerator.
Unplug the refrigerator.
Empty the refrigerator. Put all sealed containers and packages into a cooler to keep them cold. Clean the outside and check inside each container for bugs, larvae or cocoons. Discard everything else.
Remove the drawers and shelves. Wash them with hot water and dishwashing liquid in the sink. Allow them to dry.
Fill a bowl with hot water, dishwashing liquid and vinegar. Using a sponge or rags, wipe the entire interior of the refrigerator. Rinse with fresh hot water and clean rags.
Wipe the gaskets around the door. Pull them out a little so you can wipe between the gasket and door, using a rag wrapped around a Popsicle stick. Check for worn spots or holes. If you are getting bugs in the refrigerator, it may need a new gasket.
Pull the refrigerator out and clean thoroughly behind and under it. Clean the coils with a brush or vacuum. Also look under the refrigerator for a drip pan. If it has one, pull it out and wash it. Push the refrigerator back into place.
Replace the drawers and shelves. Put the food back into the refrigerator.
