Bedbugs, German Roaches and Fleas
These here pests are the worst of the worst. You can't keep them out with outside services, because they hitch a ride right past all those barriers. You can get many of these critters from friends and family staying over, staying at a hotel (even the nice ones), buying something used from other people, or from a family pet in the case of fleas. If you get these nasty and harmful critters inside, specialty treatment is needed to eliminate the infestation.
*Not covered with quarterly pest control or one time pest treatments, as these pests cannot be prevented with product barriers as other cockroaches are because they hitchhike on people or objects to get into your home.
