Bites on dogs and cats will look much like bites on people, and the pet owner may actually suspect a mosquito or flea bit the pet. As with people, bed bugs do not stay on pets, but return to a protected harborage site after feeding. In addition to bites, the presence of the bug’s feces, cast skins and the animal’s irritation at night are also indicators of bed bugs biting pets. Therefore, one of the best things to do is inspect the pet’s bedding and frequently groom the animal while being vigilant for the telltale signs of bed bug presence.
The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
