Bed Bug Lookalikes and Why they Matter

August 27th, 2020 by Rove Pest Control in Bed Bugs

In planning a course for a high school cross country team, I became keenly aware of how much the human mind gravitates toward shortcuts. This happens even when shortcuts turn out to make the process longer. We see this all too often in the pest control world and it happens quite frequently with Bed Bugs. The key place people take shortcuts is on identification. Here are the bed bug lookalikes and why they matter.

Coxae Nearly Touching

Chimney Swift Bug

This bug looks quite similar to the common bed bug, but the key to identifying them is underneath.

I know, nobody wants to think about bed bugs even existing. Why would one want to flip it over like they are going to tickle its belly puppy style? Well, by flipping it over and observing the coxae, you can learn a lot about where it came from. As you may have guessed from the name, chimney swift bugs feed on chimney swift birds. Chimney swift birds like to hang out in chimneys. Knowing their name is key to finding the source of the population. It is also worth noting that the Chimney Swift Bug is not nocturnal like the common bed bug.

Poultry Bug

The Poultry Bug also has middle and hind coxae nearly touching at the center of its body. The differentiator between the Chimney Swift Bug and the Poultry Bug is in the beak. If the beak touches the hind coxae, it is a poultry bug.

Coxae Widely Separated

Barn Swallow Bug

If you are starting to sense a pattern in the naming, you have probably guessed that Barn Swallow Bugs feed on Barn Swallows. Even though all of these blood-sucking bugs have preferred hosts, they will wander out in search of a new host if the host leaves or the population grows too big. The big kicker with the Barn Swallow Bug is that it can be confused with a Bat Bug. Both of these bugs have longer hairs than the common bed bug. For those that know the difference between bed and bat bugs, they shortcut right to hair length in identification. The problem with this is it misses the possibility of the culprit being related to barn swallows instead of bats resulting in a lot of frustration. Before worrying about hair length, check the length of the 4th antennal segment after the distance between the hind coxae. If it is the same length as the 3rd segment, you are looking at a barn swallow bug.

Tropical Bed Bug

The tropical bed bug can be quite difficult to distinguish on its own because its differentiator from the common bed bug is on the relative size of the pronotum. The Tropical Bed Bug has a narrow pronotum. By narrow, it means that the sides extend only slightly beyond the eyes whereas the common bed bug and bat bugs have a broad pronotum. The sides extend well beyond the eyes. This is easier to tell if you have seen many bed bugs or if you have one of each side by side, but can be more difficult with just one sample.

Bat Bug

The Bat Bug feeds on bats. It has wing pads that are broad at the inner margin and hairs that are long in relation to the eye width. Bat bugs are often confused with the common bed bug but also easily confused with barn swallow bugs. If it is a bat bug, you have some bats to find. If it is a barn swallow bug, you have or had a barn swallow issue as the source cause. Treating either of those as a common bed bug will lead to a lot of wasted time, effort and money.
