Eggs removed from human/mammal presence can go dormant for 2.5 yrs. Abandoned rooms/homes, items in storage.
When back in presence, the eggs will continue to incubate where they left off.
No true. Depending on the level of infestation, you can kill them all off in 2 weeks with Diatomaceous Earth. The Secret is that they love hiding in baseboard trim, so dust the hell out of it. It works when the bugs walk over it, the micro fine crystals slit up their body’s and they die out. I tried this when I had an infestation (ironically after getting a night stand and dresser from some Indian people) My wife would have little dots on her bac. Dusted the hell out of the bed, baseboard and rug. Left it for 2 week, vacuumed it up. No infestation. Safe for family and pets. Great for fleas and lice too.
