Will bedbugs return if you buy a new bed and new sheets?

Yes because unfortunately it is unlikely if you have had bedbugs previously in your home that you will get rid of the problem completely just by buying a new bed and throwing out the old one. Because in many cases bedbugs will have already created their hiding place and laid their eggs somewhere other than in the bed or mattress, such as in nearby furniture, or in the carpet or in crevices in the walls or floor nearby. Eggs laid nearby when the old bed was there may well hatch and new bedbug nymphs will be born after the new bed has been installed so that simply will not solve the problem. Also unfortunately bedbugs do not seem to be particular about human cleanliness. The sad fact is they seem to equally like feeding off people who are spotlessly clean with nice new sheets as off people who are smelly, do not wash very often and do not change their bedlinen for weeks at a time and bedbug infestations occur in the cleanest of homes as well as the filthiest.
