I used to do offsite work at an auto auction. If you think about it, lots of cars sold at auction are repossessed cars, impounded cars, abandoned cars, etc.
It’s not uncommon to find drugs in these cars. I’ve found some myself. And the times I’ve seen drug sniffing dogs at work at an auto auction was truly amazing. But bedbug sniffing dogs? Just wow.
New homebuyers need termite-sniffing dogs. (Although, read that HUMANS can detect termites by odor).
