Not only do cockroaches carry diseases, they are also unsightly, especially in a kitchen. Dishwashers create a perfect environment for roach infestation by providing moisture, food, warmth and darkness. The best way to get rid of roaches in your dishwasher is a two-pronged approach that eliminates existing pests and prevents a new infestation.
Things You'll Need
- Boric acid
- Roach baits
- Gel pesticide
- Caulking gun
Sprinkle a thin line of boric acid behind the dishwasher, stove and refrigerator, as well as under the sink where plumbing pipes enter the kitchen.
Squeeze a thin line of pesticide gel in cracks and crevices around the dishwasher.
Attach roach baits to walls near the dishwasher and other kitchen appliances. Place them close to the floor. Follow the manufacturer's directions as to how often to replace them.
Insert a thin bead of caulk in crevices around pipes under the kitchen sink and any other cracks and crevices in the kitchen.
Clean up crumbs and wash grease off of kitchen appliances.
