What are the signs of a bed bug infestation?

Signs of a Bed Bug Infestation

In the United Kingdom, bed bug infestations can occur in any household, regardless of cleanliness. Understanding the signs of an infestation can help you address the problem before it worsens. Bed bugs are small, elusive creatures that typically come out at night to feed. While they can be difficult to spot, several tell-tale signs can indicate their presence.

Physical Evidence of Bed Bugs

One of the most definitive signs of a bed bug infestation is finding the insects themselves. Bed bugs are small, reddish-brown insects about the size of an apple seed. They prefer to hide in cracks and crevices near sleeping areas, such as mattress seams, bed frames, and even behind wallpaper or under skirting boards. Inspecting these areas closely with a flashlight can sometimes reveal live bugs.

Blood Stains and Fecal Matter

After feeding, bed bugs often leave behind small blood stains on sheets, mattresses, or pillowcases. These stains can appear as tiny rust-coloured spots. Bed bugs also excrete fecal matter, which looks like small black or dark brown spots, often found along mattress seams and in bed frames. This waste material can emit a strong, unpleasant, musty odour, which is another possible indicator of their presence.

Bites and Skin Reactions

Another common sign of a bed bug infestation is the presence of bites on skin. Bed bug bites are often grouped together in small clusters or rows and can appear as red, itchy welts. However, not everyone reacts to bed bug bites, so their absence does not necessarily mean you are free of bed bugs.

Unusual Odours

A large infestation might result in a noticeable smell. Bed bugs emit pheromones, which can produce a sweet, musty odour akin to overripe raspberries if the infestation is significant. If you detect an unusual smell in your bedroom, it’s worth investigating further.

Shed Skins and Eggs

Bed bugs molt five times before reaching maturity, shedding their skins each time. Looking for these old exoskeletons, which are pale in colour, can help identify an infestation. Additionally, bed bug eggs are tiny, about 1mm, and are white or translucent, making them difficult to spot unless in large clusters.

If you suspect a bed bug infestation, it’s crucial to act swiftly to minimise the issue's impact. Professional pest control can effectively eliminate bed bugs and prevent future problems.
