Not everyone knows what bed bugs look like. They aren’t a pest that you’ll see actively invading your home like ants or spiders.  If you’re one of the lucky few, you’ve never come into contact with bed bugs before. If you’re not so lucky, you may have had bed bug bites but not seen the bugs themselves. Many people also know a friend or family member that has dealt with bed bugs before. If you find a bug in your home, or worse- your bed, and need to know if it’s a bed bug, you’re in the right place.


 It is crucial to know what pest you are dealing with if you are experiencing any type of infestation. Not all treatments are the same so the specific pest must be identified. Often times, people find a bug and use the internet to search for what it could possibly be. There are so many variations and slight differences in the insect kingdom that this can be difficult for the untrained eye. This article will help you identify basic bed bug features and the physical signs they leave behind.
