Well I wouldn't say its an infestation just yet its not like I see a bunch because its not like that at all , only a few but that can become a problem I know. every time I see one I kill it but I feel as if the numbers are decreasing. I used the tape around the bottom edge of the tank and its sticky enough to catch a bug put not strong enough to keep a finger or even possible to handle how jade moves if she gets stuck. Hopefully this works actually hopefully these roaches leave !
