There are several ways in which dwellings can become infested with bedbugs. One common way is for them to be picked up while traveling or when staying at temporary lodging such as hotels, bed-and-breakfasts, hostels, or motels — which are places that have traditionally been associated with being at a higher risk for housing bedbugs due to their higher rate of turnover and continual influx of temporary residents. Once acquired at such travel locations, the now hitchhiking bedbugs may then be transported and brought back to the homes of the guests in their luggage where a new infestastion can then take place inside the home.
Bedbugs can also be picked up inadvertently through bringing infested furniture or contaminated, used clothing into a household. Though such furniture does not necessarily have to have been previously owned or discarded — since even brand new furniture can be exposed to bedbugs during storage or in delivery vehicles. Nor do the used clothes have to be clothing that has been obtained through borrowing, secondhand purchase or through donation — since any exposed and unwashed apparel is capable of transferring bedbugs.
Confirming the presence of bedbugs can be a tricky matter — particularly in cases where an infestation is light, recurrent, or when a user has no prior experience in dealing with bedbugs. Because of this, it is advisable that the home owner contact a pest control expert to get the infestation treated immediately before the infestation has a chance to grow and spread. In light infestations, bedbugs will often lodge themselves unnoticed into the tiniest of crevices away from viewing and usually coming out to feed only deep in the middle of the night. But this rule is not set in stone as there will be exceptions — particularly in heavy infestations where it will then become common to see bedbugs crawling about in broad daylight.
