Signs of Bed Bugs: How to Identify an Infestation

If there were ever two words guaranteed to make you itchy, it’s “bed bugs.” These tiny biting pests are notorious for causing stress and sleepless nights. Skilled at hiding and easily hitching rides into San Diego homes, bed bugs can quickly become a serious problem.

Recognizing the early signs of an infestation is crucial to stopping it before it spreads. Harbor Pest Control, treating bed bug infestations since 1948, has the expert guidance you need to identify and handle these pests.

What Bed Bugs Look Like

Adult bed bugs are about the size and shape of an apple seed. They are flat and brown when they haven’t eaten, but become engorged and reddish-brown after a meal. 

Bed bug nymphs go through several stages of development before becoming adults. Starting out as small, translucent bugs, they become progressively larger and darker through several molts. 

Bed bug eggs are tiny and white and usually stick in seams and cracks where they won’t be disturbed.

Key Signs of a Bed Bug Infestation

Identifying a bed bug infestation is much easier if you know what signs to look for and where to look for them. A few signs are rather obvious, while others are harder to identify. 

Live Bed Bugs

Spotting live bed bugs is a clear sign of an infestation. These nocturnal pests are most active at night. Still, during the day, you can check the places they hide: mattress seams, the space between mattress and headboard, behind picture frames and curtains, inside electrical outlets, in upholstered furniture seams, and in floor cracks.

Bites on the Skin

Bed bug bites are often the first sign people notice, making them a strong indication of an infestation. But how can you tell them apart from other bug bites? It can be tricky, since they look and feel similar. Typically, bed bug bites appear in clusters or uneven lines and usually appear on skin exposed during sleep, such as the neck, arms, or legs.

Stains or Spots on Bedding or Mattresses

After feeding, bed bugs often leave tiny drops of blood behind, which can appear as small red spots on your bedding. They also leave brown fecal smears or dots in the areas they frequent. These signs are most commonly found along mattress seams or in the sheltered spots where bed bugs like to hide.

Eggs and Shed Skins

As bed bugs mature, they molt several times, leaving behind shed skins. You’ll usually find these in the same sheltered areas where they hide during the day, spots that are also likely to contain their eggs.

Odor

In cases of a large or widespread infestation, you might notice a musty odor in heavily infested areas. This smell comes from bed bug secretions and is often compared to the scent of wet towels left in the laundry too long.

Why Acting Early Matters

Recognizing the signs of a bed bug infestation is crucial because early detection makes treatment much easier. Unlike most pests, bed bugs don’t follow predictable patterns, which makes prevention difficult. That’s why spotting an infestation early is so important for effective elimination.

Once they get into your house, bed bugs will reproduce and spread quickly. The longer they’re allowed to remain, the greater the infestation will become. The larger the infestation, the harder it is to treat, which leads to a greater financial and emotional toll on you. 

By identifying and treating a bed bug infestation in its earliest stages, you can eliminate it quickly, saving you time, money, and stress.

What You Can Do to Prevent Bed Bugs

Unlike most pests, bed bugs don’t start by hanging around your yard; they’re true indoor hitchhikers. They travel into homes by catching a ride with people, often from infested hotel rooms, schools, public spaces, or other places where people gather. Bed bugs can easily crawl into bags or cling to clothing, which means they can sneak into your home without you even realizing it.

To prevent bed bugs, you have to be vigilant.
