Shape and size:
There are a number of different yellow jacket species. As indicated by their name, yellow jackets have a black and yellow head with a patterned abdomen resembling stripes. Yellow jackets tend to be more aggressive during the early fall season as activity increases in reaction to cooler weather.
Signs of a Yellow Jacket nest:
Yellow jackets build nests in the ground or in hollow areas such as eaves and attics. They can be found anywhere humans can be found – they particularly enjoy invading outdoor activities where sweets may be present, which can be an issue for those that are allergic to bee stings. Check for nests near recycling bins or other areas where sugary content may be present.
