If what you are seeing is a completely white bug then you are extremely fortunate. These are roach avatars are very valuable. Capture as many as you can and establish a colony of them as you would an ant farm in an aquarium. In 3 months harvest half of them to a gourmet restaurant. Yummy!
You might have a giant water bug, sometimes known as toe-biters or electric light bugs. These bugs like water and attack other insects and small animals.
Similar to the cockroach other bugs include the ground beetle, water bug, crickets, long-horned beetles, and leaf-footed bugs. Boric acid helps control roaches.
