Wasps are notorious for their aggressive behavior and painful stings. Since these pests are capable of stinging multiple times in a row without dying, they can be deadly – especially to young children or those with an allergy. While wasps are dangerous year-round, they become particularly active and hostile when winter is approaching. But, why are wasps more aggressive in the fall?

Limited Food Sources

From fruit and nectar to barbecue leftovers, wasps have easy access to all sorts of food sources throughout the spring and summer. However, as fall sets it, it becomes increasingly difficult for them to find anything to eat. Not only does this prompt the wasps to search through your trash and other high-traffic areas for food, but it also causes them to become more aggressive. To deter wasps from invading your space in search of food, be sure to:

  • Pick up fallen fruit
  • Store pet food bowls inside
  • Avoid leaving leftovers out
  • Use lidded trash bins

Higher Populations

Queen wasps begin laying eggs in the spring when the weather begins to warm up, and they continue to reproduce all throughout the summer. That means the colony’s population is at its highest once fall comes around. Paired with the limited access to food, this peak in population increases competition and hostility in wasps during this time of year.

Protecting the Queen

Wasp colonies are very protective of their queens all year long. If even one wasp detects a threat, they will release special pheromones that alert the entire colony of a nearby danger. This can lead to deadly swarms, which become even more harmful in the fall because of the increased populations and higher level of aggression.

Searching for Warmth

Though most wasps will die once temperatures drop, queens typically seek out a warm and protected area where they can survive the winter. That makes your home the perfect place for a wasp to wait out the cold season. For this reason, it’s important to keep an eye out for wasps in spaces such as:

  • Attics
  • Sheds
  • Wall voids
  • Eaves
  • Porches
