Hey Ruth! If there are absolutely no signs of bed bugs (upon close inspection), its unlikely that they are the cause for the bite marks. I recommend taking another look for dark brown marks (dried blood) and other signs of their presence. Regardless, if you want to kill any bug on that mattress, just get a handheld steamer and blast it. The heat will kill everything and its completely natural. Hope that helps!
Bed bugs are an increasing cause for litigation. Courts have, in some cases, exacted large punitive damage judgments on some hotels. Many of New York City's Upper East Side home owners have been afflicted, but they tend to be silent publicly in order not to ruin their property values and be seen as suffering a blight typically associated with the lower classes.
The bed bug is a universal problem yet it can be dealt with on a regular basis. used items and new items carry bed bugs. always wash and dry for 20 min. ( its the heat that kills the bug). bed pillows need to be washed and dried on a regular basis and the beds head board are full of body skin cells that attract the bugs. a good old cleaning with vaccum and wipe down is needed. keep your vac cleaned and bag empty after each use, the bugs are in the vac.
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.
