Do Bed Bugs Have Long Legs?

Do Bed Bugs Have Long Legs

No, bed bug legs are quite short which only allow them to crawl slowly over surfaces. When bed bugs are floating on water, their legs are not long enough to make them stand over the surface of the water using the surface tension. Their legs make them stay low to the ground whenever they walk, which also helps keep them discreet around potential predators or danger.

What are bed bugs?

Bed bugs are parasites that are related to cicadas, aphids, and stink bugs. Bed bugs belong to the order Hemiptera. Compared to these other insects though, bed bugs have evolved to feed on humans for our blood.

These insects, much like fleas or lice, cannot survive without access to warm-blooded animals for long periods of time. But unlike those two blood-sucking insects, bed bugs do not need to live on their host’s body. Bed bugs only need physical contact with their hosts during feeding, after which they return to their hiding places to digest their blood meal and to keep safe. They hide away in our mattresses, box springs, bed frames, carpets, floors, and furniture.

Bed bugs feed mostly during the night when their host is asleep so they are less likely to get caught.

How does one’s home become infested with bed bugs?

Bed bugs frequent places with heavy human traffic such as hotels, dormitories, schools, hospitals, and public transportation. If you as much as sit on an infested bed or seat, one pregnant female bed bug can crawl onto your clothes or into your bag. The bed bug will grab onto you until you get home and put down your bag or lay on your bed.

The bed bug will crawl down and immediately start looking for a hiding place, or harborage. They will then learn your sleeping habits and know the optimal time to feed on you. The female will lay eggs which will hatch into male and female baby bed bugs, or nymphs. These nymphs will become sexually mature adults and produce their own families. Before you know it, you have a sizable bed bug population in your home.

How to identify bed bugs

How big are bed bugs?

Bed bugs are around the size of an apple seed. They are around four to five millimeters long. They can balloon to up to three times their size after a blood meal.

The bed bug’s abdomen is twice as wide and four times as long as its thorax. The abdomen is round when seen from above. A bed bug’s body is flat before feeding and round and rotund after feeding.

Their body is segmented with rudimentary wings on the back. 

They have six legs, the first pair extending from the thorax, while the other two pairs extend from the abdomen. Each leg has one bend, and their feet have tiny hooks that help the bed bug grab onto the surface they are scaling.

What color are bed bugs?
