To get rid of water bugs, remove clutter, clean the house, set bait traps, place boric acid near the nest and seal all potential points of entry. Contact a pest control specialist for severe infestations.
- Clean the area
Water bugs hide and live in cluttered areas. Move furniture and kitchen items around, and remove any debris. Use cleaning products to thoroughly clean all counter tops, floors and surfaces.
- Set bait traps
Go to a hardware or home goods store, and purchase cockroach bait. To prevent contamination in a home, buy sealed bait with contained poison. When the water bug brings the bait back to its nest, the other water bugs eat the insecticides.
- Sprinkle boric acid near the nest
If you know where the water bugs are coming from, sprinkle a fine dusting of boric acid on the ground near the area. When the water bugs walk on the powder, it is absorbed through their legs and antennae, exterminating them. A mixture of equal parts sugar and baking soda also works.
- Seal entry points
Check the home for cracks or crevices in the wall, broken screens and loose window sills that can serve as entry points. Use caulk to seal cracks, and replace or repair window screens.
