Even if they don't transmit disease, bedbug bites are bad enough. They result in itchy red welts, and a single bedbug may bite more than once. The bite itself is not painful and often goes unnoticed at first. The itch reaction sets in later. Bedbugs tend to produce clusters or lines of welts as a single bug moves around and feeds multiple times.
The harm caused by the bites increases if you are allergic to the insects. Allergic people who are bitten develop itchy welts up to 8 inches across. Their skin blisters and develops groups of swollen pus sacs. A rash that looks like hives develops on other areas of the skin.
Labor and Costs
Bedbugs will in the end demand one of two things from you. You will either have to go through the effort of checking every piece of furniture, every wall, every floor and every item of clothing for them, and then cleaning them all, or you will have to call in pest control professionals. Choosing the latter can prove expensive, because the exterminators will have to make multiple visits to ensure the problem is under control. It can also involve the use of harmful chemical pesticides. However, it is the recommended approach.
Apartment and Condominium Problems
Bedbugs create an additional layer of problems for owners and residents of apartment buildings and condominiums. The bugs can enter the walls and floors of an infected apartment and travel into other nearby apartments, creating secondary infestations even if the residents practice good preventative measures. Controlling an infestation in an apartment building or condominium requires a coordinated effort involving all the units and residents.
