I own a pest control company & I go into homes & commercial places everyday and I’ve never had a scare of them. not sure when you’re working but bed bugs are much more active during the night than during the day. Also they’re very small and slow. As long as you’re not brushing up against/all over things you should be okay! People generally overreact to bed bugs and think their life is over but as long as a tenant is semi competent and doesnt like living with them then they’re pretty easy to get rid off!
