Their nests are also made of a paper-like material that forms a circular comb of cells which opens downward. The nests are often located under eaves, behind shutters, or in shrubs or woodpiles. Hornets are black or brown with white, orange or yellow markings and are usually larger than yellow jackets. Their nests are gray or brown, football-shaped, and made of a paper material similar to that of yellow jackets' nests. Hornets' nests are usually found high above ground on branches of trees, in shrubbery, on gables or in tree hollows.
Fire ants are reddish brown stinging insects related to bees and wasps.
Their prominent mounds, common in warmer climates, may measure up to three feet in diameter and 18 inches in height, and can contain up to 250,000 ants. It then pivots at the head and typically inflicts about eight stings in a circular pattern. Fire ant venom has a high concentration of toxins, which cause burning pain. Since this activity can be dangerous, a trained exterminator should be hired. If you encounter any flying stinging insects, remain calm and quiet, and move slowly.
