Vinegaroons, also known as whip scorpions, are 8-legged arachnids that resemble scorpions. Unlike scorpions, these arachnids have thin tails with no stingers or venom glands. These creatures can range from 1 to 3 inches in length and can weigh up to 12 grams! Although vinegaroons have 8 legs, only 6 are used for walking. The first two legs actually serve as antennae-like organs (not to be mistaken with their large scorpion-like pincers, which are used to crush their prey).
While most vinegaroons are small in size, their large legs, whip-like tail, pincers, and large abdomen can make them appear to be much larger. Similar to scorpions, these pests have one pair of eyes towards the front of their head and 3 on each side. While they don't have venom glands and aren't venomous, they do have glands under their abdomen that spray acetic acid and caprylic acid when the pest feels threatened. This acid tends to have a vinegar-like smell, which is where the name "Vinegaroon" comes from!
