Q and A

Q. How does bug repellent work?

A. Who wants a bug to spit on you or well inside of you. That's gross and could cause rashes that you'll itch for days. Just use spit protector which is better known as bug repellent.

Don't let them take your blood because hey, you only got so much blood pumping in there.

Insect repellent oil works by discouraging insects from landing on, or even coming near to, the surface to which it is applied. You may see insects nearby, they probably won't be landing on you if you are protected.

According to ehow.com, The repellent masks the scent of a human, and at the same time, releasing a scent that is unappealing to insects. Some insect repellents also have an ingredient which causes the insect's sensors to malfunction, thus confusing it so that it is not able to land and bite the human or animal. This ingredient is commonly found in synthetic oils and sprays which contain DEET.

You may not kill the bugs in general but you do protect yourself from itches, rashes and just losing your blood in general.
