How to Detect Signs of a Bed Bug Infestation

Bed bugs are small, elusive pests that often go unnoticed. They hide in cracks, crevices, and soft furnishings, emerging at night to feed. Catching an infestation early can help prevent it from spreading. Here’s what to look for and where to look.

Signs You May Have Bed Bugs

Bed bug infestations often leave behind visible signs, especially around sleeping areas. Knowing what to look for can help you spot a problem early. Check mattresses, bedding, and nearby furniture for the following indicators:

• Small, itchy bites in a line or cluster on your skin • Rust-colored stains or smears on sheets and mattresses • Clusters of dark brown or black spots from dried excrement • Shed skins or casings left behind after molting • A subtle, sweet and musty odor, particularly in heavily infested areas

If you notice one or more of these signs, it’s important to investigate promptly and consider contacting a pest control professional for confirmation and treatment options.

How to Check for Bed Bugs

Start by inspecting areas where people sleep or rest. Use a flashlight and magnifying glass to examine:

  • Mattress seams and box springs

  • Headboards and bed frames

  • Upholstered furniture

  • Behind wall outlets and baseboards

Bed bugs are about the size of an apple seed and reddish-brown in color. Look for signs like dark stains, shed skins, and tiny white eggs.

How to Find Bed Bugs During the Day

Although bed bugs are most active at night, they can still be found during the day if you know where to look. They often hide inside mattress seams, behind wallpaper, in cracks in wooden furniture, and inside dresser drawers. Their flat bodies allow them to squeeze into tight spaces, making daytime detection challenging but possible with a thorough inspection.

What to Do If You Find Bed Bugs

If you confirm signs of a bed bug infestation, taking the right steps early can help contain the problem and prevent it from spreading. Here’s what to do if you find bed bugs in your home:

  • Avoid moving infested items to other rooms

  • Wash and dry bedding and clothing on high heat

  • Vacuum thoroughly around sleeping areas

  • Contact a pest control professional for inspection and treatment

DIY methods may offer temporary relief, but professional treatment is often necessary to fully eliminate bed bugs and prevent reinfestation.
