Possible Signs of Bed Bugs
The following are common signs of bed bugs and can be symptoms of a possible infestation:
Small red to reddish brown fecal spots on mattresses, upholstery or walls
Molt bed bug skins, their white, sticky eggs or empty eggshells
Red, itchy bite marks, especially on the legs, arms and other body parts exposed while sleeping
According to NPMA's 2018 Bugs Without Borders survey, bites are the most commonly reported sign of an infestation, according to 92 percent of respondents. More than half of people reach out for treatment after discovering bites and welts on their bodies. Although some people immediately develop a skin reaction to bites, others may take two to three days before showing obvious symptoms or any symptoms at all, meaning that people could be unaware of a bed bug problem until a full-blown infestation has taken root.
Very heavily infested areas may have a characteristically sweet odor
Although the actual bite of bed bugs is painless, most people develop an allergic reaction to the saliva (which also acts as a numbing agent) injected by the bug as it feeds. Swelling and itchy, red welts can be signs of a bed bug infestation. However, some people do not have reactions to bed bug bites at all. In addition, bites from other insects, such as mosquitoes, are often mistaken as bed bug bites. Unlike many other pests, bed bugs are not known to spread disease to humans.
If you notice signs of bed bugs or suspect you have a bed bug infestation, it is important to contact a licensed pest control professional to confirm the infestation and recommend a course of treatment.
