What Makes Yellowjackets Aggressive in the Fall?

 In Pest Control, Pest Control Tips, Pest Prevention

Everyone knows that bees and wasps play important roles in our environment. However, yellowjackets are better known for their aggression and painful stings. During the fall, yellowjacket populations soar, causing overcrowded nests and hungry wasps. These conditions lead to increased aggression and propensity to sting, along with a higher likelihood to seek out humans for their food. If you’ve started to notice more yellowjackets around as the summer wanes into fall, you’re not alone. Learn how to avoid yellowjacket stings with Western Exterminator, formerly Hitmen technicians!

When Do Yellowjackets Sting?

During the spring and summer, yellowjackets and other wasp species are happily sustained by the amount of nectar they can obtain from new flower growth. However, a steady diet means a steadily growing population, which in turn causes yellowjackets to leave their overcrowded nests. As we get deeper into the heat of summer, flowers start to die, and yellowjackets’ main food source starts to deplete.

When yellowjackets are cramped and hungry, they turn to our homes in their search for food. Already agitated by their diminishing living conditions, yellowjackets are quick to sting anyone that they perceive as a threat. What’s worse, when they sting, they release a pheromone that tells others nearby to help them sting the victim. People that are allergic to wasp stings could experience anaphylaxis resulting from a yellowjacket sting, which can be as serious as hospitalization or even death.

How to Prevent Wasps in the Fall

To avoid the dangers of a yellowjacket outbreak at your picnic or outdoor event this fall, you have to learn how to keep them away from you:

  • Seal or cover any food when outside
  • Seal trash cans with a secure lid
  • Seal any cracks and crevices in your house
  • Eliminate standing water buildup
  • Cover swimming pools, birdbaths, and spas
  • Avoid floral perfumes and bright colors
  • Avoid walking barefoot through the grass
