One of my favorite calls relates to how scorpions get into bathrooms or showers. People tell me they come up drains and that is incorrect. Arizona Bark Scorpions enter your home by crawling up stucco and gaining access into your attic. They then crawl around and under the insulation and finally they come to a recess light or something that was cut through the ceiling drywall. See all those cracks and if your home isn’t sealed well enough they will fall right into your house. Sometimes there are lights or fans right above the bath or shower and they just fall in. So here is my advice, pull down the plate that covers these holes and caulk the hole. This should be done on the top floor ceiling or if you live in a single story house the ceiling. On our website is a list of things we attempt to seal when we perform a Home-Sealing.
