What do bed bug droppings look like?

Updated April 17, 2017

The droppings that bed bugs leave behind are very distinct, and recognising them is one of the best ways to know if you have bed bugs. The blood-sucking insects hide during the day in the mattress, bed frame, skirting board or in cracks and crevices in the floor, so you may never see them.

Bed bug droppings

Dark brown to black spotted stains appear on pillows, sheets and other bedding in a room infested by bed bugs. The telltale piles of dark excrement are left behind on resting sites after they eat.

About the bed bug

Bed bugs can be transported on clothing or infested second-hand furniture to any home. When the lights are turned on at night, you will see reddish-brown, oval-shaped bugs about 6 mm (1/4 inch) long on and around your bed.

Night time creepy crawlies

Bed Bugs are nocturnal. During the night they crawl onto a sleeping person, pierce the skin and suck blood. The person may have tiny red spots and itching, similar to a mosquito bite, as a result of a bed bug bite. The insects are very active and can crawl from room to room during the night.

Transporting bed bugs

Charity shops, car boot sales and second-hand clothing and furniture are common ways for bed bugs to get into your home. Inspect all furniture you buy carefully, vacuum the furniture, and spray it with insecticide before bringing it into your home.

Preventing and treating bed bugs

To prevent bed bugs or get rid of them, spray skirting boards, cracks and crevices with a specialist insecticide. Spray bed frames and springs with a pesticide containing 1 per cent malathion or pyrethrin. Mist the mattress with same solution but do not soak it. Be sure to wash bedding thoroughly on a hot temperature and keep your house clean.
