1. You have small red bites that itch and which you can’t explain otherwise. Bed bugs usually bite on the neck, arms, or shoulders but sometimes suck blood from the legs and ankles instead. They typically bite in a straight line, so that’s one signal that the bites are from bed bugs.
Nonetheless, it can be difficult—even for doctors— to determine if bites are from bed bugs until a pest-control specialist thoroughly examines your home using a specially trained dog that sniffs them out.
2. You see actual bed bugs or signs of them. Obviously, if you spot a bed bug, you have a problem. Adults are 4-5 millimeters long and 1.5-3 millimeters wide. They are light brown to reddish brown and oval. Nymphs are translucent and grow darker as they go through their molting stages.
Tiny white eggs, dark liquid feces spots, and discarded shells are also visible evidence of bed bugs.
However, even if you see bed bugs or signs of them, the extent of the infestation and the locations of their hidden nests can be hard to pinpoint.
3. You smell the scent of rotten raspberries. This unpleasant odor often accompanies bed bug infestations.
What to Do
If you suspect your home is infested because of one or more of these signs you have bed bugs, don’t hesitate to call a pest-control company that specializes in their detection and removal. Once you have an infestation, it takes professional-grade pesticides and expertise to ensure their eradication, and the sooner you get rid of them, the better.
