Battling fungus gnats in the same spot in spray foam backgrounds. I keep getting gnats right where the foam meets the substrate. In multiple tanks. Haven’t been able to find a solution to this specific problem. Both tanks with backgrounds have springtails so I don’t know how this keeps happening. Should I scrape off and start from scratch? Tank is complete dry it’s an avicularia tank(I add springtails when I notice gnats and while cycling so theres at least a few in there). Used pond and stone and used the method where I apply everything before it dries
