How likely to catch bedbugs going out to lunch with my relative whose house is infested? I have an elderly relative whose house unfortunately has been infested with bedbugs for several months. I live across the country and am home for the holidays and would like to see her since she is aging rapidly and recently had some serious health issues.
Store the luggage away from the infested room, preferably in the car or in the bathroom. Inspect yourself and your clothes that you are wearing currently to see if bed bugs have crawled on them. Do not apply any insecticide on your person; rather brush or dust the clothing. Once you are home, brush your clothes again.
While bed bugs can be found in your car, it's not particularly likely. Bed bugs would usually use a car just to move from host to host, and probably won't stick around for long. The odds of you finding bed bugs nesting or mating in your car are very slim.
For vacuuming your car, choose a powerful vacuum with a HEPA filter. Make sure it has a handheld attachment for those corners and crevices. There are vacuums on the market specifically for bed bug problems, so if you have a bit of money to spend, one of these might be a good investment.
