i have them to damit. i started treating the other day. they are like cock roaches just dont go a way. but from what a read, there life span and egg cycle. is the best attack. kill the bugs and then treat the eggs that they laid.break the cycle and it will slow them down. i got some doktor doom spider mite spray, and some doktor doom bomb, treated the plant, then bomb and then in a week do it again. good luck
