Discovering a bug in your house is an unpleasant experience. Discovering an insect has been tucked into bed with you all night? That's enough to send a chill down your spine. It could be a one-time incident – or it could be a bed bug.

There are a number of other bugs that look like bed bugs, so how can you be sure this new intruder is a bed bug? There are a few things to look for.

What caused that bite?

Bite marks are one of the first red flags that prompt people to suspect a bug infestation. Even a small mosquito bite might be enough to send a diligent homeowner on a massive inquisition. But bite marks are bad indicators of the type of pest you are dealing with. Mosquitoes, spiders, fleas, bed bugs and even fruit flies, in rare cases, can leave behind itchy red bumps. Allergic reactions and high stress levels are also culprits for skin irritation.

What if I've got a bite and a bug?

So you think you've found your culprit? You've taken the prisoner of war and locked him up in a plastic sandwich bag (you should, this is useful evidence for a pest management professional). You are certain it is a bed bug, but is it? Or are you on a trail of bugs that look like bed bugs? Take a look at the following checkpoints:

Is it a bed bug or a flea?

All of the above are bugs that look like bed bugs, but most of these bugs don't bite. If you have clear evidence of repeated bite marks, you might be able to eliminate the others and focus on the flea. Fleas are most commonly found on animals, but are not picky about their hosts and will feed on humans too. The difference between bed bugs and fleas is that bed bugs are shaped more like an apple seed and crawl. Fleas are much smaller and jump when disturbed.

Bed bugs can create high levels of stress and anxiety. If you suspect you have an infestation, it is best to contact a professional pest management company.
