I manage properties in Halifax, Nova Scotia, Canada. We don't have scorpions, but we have mice and minor insects. If you are renting, your landlord is liable to be found negligent should anything happen to you or your baby, IF you have informed him of the problem and he has not covered that access hole by the tub in a reasonable amount of time. Scorpions are pretty big and with the exoskeleton and claws I doubt they can fit through a 1/4 inch hole like a mouse can. There is no reason for them to be able to get into your home. We have trouble keeping mice out, but we wouldn't have a problem keeping scorpions out.
