Bite Vac is a small, hand-held device that's meant to reduce the itching and swelling that's often caused by bug bites in just seconds. It's been designed to treat bites from various common types of bugs, such as ants, mosquitoes, bees, and horseflies, regardless of whether those bites are on your arms, legs, neck or head. The device comes with four interchangeable tips, including two small ones that have been made for smaller bites and two larger ones for bigger insect-induced wounds.
