5 Common Signs of a Bed Bug Infestation and What to Do About It

Bed Bug Infestation

Bed bugs, those elusive and troublesome pests, have become a widespread problem in households and establishments across the globe. To protect your home and family from these blood-sucking bugs, knowing the common signs of a bed bug infestation and how to effectively deal with it is crucial.

1. Unexplained Bites and Rashes

One of the primary signs of a bed bug infestation is waking up with unexplained bites and rashes on your skin. Bed bugs are nocturnal creatures that come out to feed on human blood during the night. Their bites are often painless but can lead to red, itchy welts, similar to mosquito or flea bites.

What to Do

If you notice these bite marks, examine your bedding and mattress for other signs of bed bugs. Look for small reddish-brown insects or tiny black spots (faecal matter) on the sheets. It’s essential to act promptly to prevent the infestation from worsening.

2. Rusty or Dark Stains on Bedding

As bed bugs feed on blood, they often leave excrement stains on the bedding. These stains can appear as tiny rust-coloured spots or dark smears. If you observe such marks on your sheets, pillowcases, or mattress, it is a clear indication that bed bugs are present.

What to Do

Immediately wash all affected bedding in hot water and dry it on the highest setting to kill any bed bugs or eggs present. Consider using mattress and pillow encasements to prevent bed bugs from entering or escaping. Additionally, contact a professional pest control service to assess the extent of the infestation and devise an appropriate treatment plan.

3. Musty Odour in the Bedroom

Bed bugs release pheromones, which emit a distinct, musty odour. This scent is often described as sweet or sickly. It might indicate a bed bug infestation if you detect an unusual smell in your bedroom, especially near the mattress or furniture.

What to Do

Inspect the area for other signs of bed bugs. Pay attention to cracks, crevices, and furniture seams, as these are common hiding spots for these pests. If the infestation is confirmed, seek professional help for effective eradication.

4. Visible Bed Bugs and Eggs

Adult bed bugs are small, flat, and reddish-brown insects about the size of an apple seed. While they are skilled at hiding, you may sometimes spot them crawling on your mattress or walls, especially during the early stages of an infestation.

What to Do

If you find live bed bugs or eggs, it’s crucial to take immediate action to prevent the infestation from spreading. Vacuum the affected areas carefully, dispose of the vacuum bag in a sealed plastic bag outdoors, and contact a professional pest control service for thorough treatment.

5. Exoskeletons and Shed Skins

As bed bugs grow, they shed their exoskeletons, leaving translucent, empty shells behind. These shed skins clearly show bed bug activity and indicate that the population is growing.

What to Do

Collect the exoskeletons you find and show them to a pest control professional. They can confirm whether the infestation is indeed caused by bed bugs and suggest appropriate measures to address the problem.


Detecting a bed bug infestation early is crucial for effective bed bug control and prevention of further spreading. You must take immediate action if you experience any common signs mentioned above. Promptly wash and treat bedding, vacuum the affected areas, and seek assistance from a reputable pest control company.
