How big are bed bugs? – see pictures to compare their size

Bed bugs are a real nuisance if you have them in your home, but one of the things many people are unsure of is what they look like, their shape, their appearance and to know what size they are. Before you call a pest control expert, how do you know bedbugs have invaded you home or room and not something else, such as other types of beetle? And of course if you have never seen one before you may wonder how to identify them.

What do bed bugs look like?

The first things to look out for is bug bite marks on the skin and other possible symptoms before assuming a bug invasion. A correct identification is necessary for the proper treatment needed, if any. The picture below shows what bed bug bites look like. If you or one of your children have bites likes this and they are sore and itchy, it could well be the result of bedbugs. It’s always best to check with a doctor just to make sure it isn’t some other condition. See the bed bug pictures and photos below to get an idea of what to look out for.

They tend to show up as dark brown colour so are quite easy to spot against a whole bed sheet or duvet.

If you do suspect an infestation, you will need to turn over all your bedding, duvet covers, pillow cases and all around the mattress. This photo shows what they look like on bed covers.

What size are Bed Bugs?

What is the actual size of bed bugs? Well it depends. Bed bugs grow significantly though their life cycle and can start of quite small from the nymph stage before becoming adult bedbugs. After feeding on human blood, they can also swell to about twice normal bed bug size. Also they lay eggs which are a bit harder to see and much smaller, sometimes found on the skin.

The images below will give you a sense of scale and beg bug sizes next to a person’s fingernail.

Treatment options

If you do find any, you will need to treat the infestation thoroughly to get rid of all the bedbug eggs as well, to prevent them returning. For a light infestation, you may get away with just washing all the bed coverings.However, for a bad infestation, you may need to throw all your bedding in the bin and replace your mattress too. If it is a devan bed, these insects can also live inside the bed, so best to replace everything if necessary. It is also well worth checking all your clothing as they can transport themselves on clothes too. Also, it may be worth while calling in a professional pest control company who have experience in this area.
