While keeping your house clean can help keep bed bugs (and of course, other insects) at bay, contrary to societal rumors, bed bugs do not exist primarily in dirty homes or living environments. The tiny creature is a non-discriminating roamer, moving from environment to environment (clean or not) via what ever opportunity arises. Not to cause the traveler to be leery or the hostess to reject houseguests, but below is a list of origins where bed bugs begin, from hotels to travelers and their luggage to secondhand purchases.
Of course, this list isn’t even close to exhaustive. Again, bed bugs are travelers, so they can arrive on your doorstep in many ways. The best option is to keep your house clean, as that detracts bugs of all kinds, perhaps adopt an animal that can help the process, and call your Phoenix pest control experts to get rid of them once and for all.
