Bedbugs are stubborn, often undetectable critters. Once they make themselves at home, they can be difficult to remove without the help of a residential pest control service. Pest-Ex, of Dothan, AL, can help detect and dispose of these nuisances.

But how do you know that you’re actually dealing with them in the first place? Residential pest control professionals say there are several warning signs to look for when on the alert for bedbugs, including:

• Bites: It’s certainly not pleasant to wake up to a series of mysterious bites on your arms or legs. These welt-like bites may appear in a line or small cluster if they’re caused by bedbugs, and will likely be red and itchy.
• Stains: When bedbugs feed, they may leave behind bloodstains that resemble little dots of rust. They’re commonly spotted along the corners of the bed. Also in these areas may be small exoskeletons, which occur when the bedbug sheds its skin as it matures.
• Odor: A large invasion of bedbugs can leave behind a strong, unpleasant odor. That’s because bed bugs emit pheromones, which produce a rich, pungent, often musty smell that could be mistaken for a gym or locker room.

If you’re at all suspicious about the presence of bedbugs in your home, it’s time to take preliminary action. Begin with an inspection of your bed by stripping the mattress and taking a close look at it, along with the box spring. Also, take a close look around the room—check any upholstered furniture, whether it’s an armchair or a sofa, and don’t forget to inspect curtains and even the carpet for signs of bedbugs. It can be tricky to peer behind furniture, but those areas—along with your bed’s headboard—are classic hiding places for these pests.
