Using sticky traps, bait stations and boric acid mixed with flour and water are some effective ways to get rid of water bugs and roaches. Sticky traps are non-toxic options.
Once a roach walks on a sticky trap, it gets permanently stuck. Set sticky traps anywhere roaches and water bugs live, such as cabinets, closets and under appliances. Sticky traps work immediately, so check and replace them often.
Bait stations contain Fipronil, which kills insects when they ingest or touch it. Roaches and water bugs often take the bait and share with others in the nest. Place the stations in out-of-the-way places such as behind furniture, in cabinets and under appliances. Keep them out of the reach of children and pets. Change the stations every few months.
Mix boric acid with flour and water, and place it in a bowl. Place it in an out-of-the-way location, such as behind an appliance or in a closet or cabinet. The solution poisons the roaches when ingested or touched. This is a toxic solution, so keep it away from children and pets.
