Reactions to bed bug bites differ from person to person from none to a full-blown allergic reaction. A mild reaction may reveal flat, red bumps at the bite sites. A more severe reaction may include an irritating itch (as in my case), or swelling. Resisting the itch is incredibly difficult, but giving in to it can cause severe irritation to the skin, increasing your risk for an infection. It’s the chemicals in the bed bug’s saliva that trigger such reactions, some lasting more than two weeks.
When people are bitten, they often do not notice at first. It’s a possibility that one reason could be that these blood sucking insects feed late in the night, before the breaking of dawn. Humans are often in a deep REM sleep during that time. Upon arising, individuals can find bite marks; however it can take up to ten days for adverse or allergic reactions to develop.
NO you cannot contract HIV from Bed bugs in fact as far as I know they haven’t been found to transmit ANYTHING they are just a nuisance and if your allergic to the bites its worse otherwise they are not dangerous. However there is always the danger from infection I mean the bites becoming infected if you don’t take care of them like any wound not HIV. And they are creepy but ultimately mosquitoes could be more dangerous if u there is west nile around or something.
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.
