I don't have bed bugs, but I do have bites! It's likely that you have other small bugs in your mattress than bed bugs. Some insect bites, such as fleas and scabies, may appear to be bed bug bites. Checking for symptoms of bed bugs in your home is the easiest way to say whether it's a bed bug or not. If you don't see any signs of bed bugs on your bed, it's possible that you're being bitten by some mosquito.
