Wasps in a nest. Pioneer Pest Management serving Portland OR and Vancouver WA talks about yellow jackets and hornets and how you can help prevent them.Are wasps showing up on your doorstep? Wasps, particularly yellow jackets and hornets tend to be more aggressive in late summer as they scrounge for food and supplies. These stinging insects produce painful stings and can be dangerous if you’re allergic to them. In fact, more than 500,000 people are sent to the emergency room every year because of stinging insects.

Although wasps are beneficial predators, you shouldn’t have to share a home with them. This is why we at Pioneer Pest Management are talking about what attracts these pests and what you can do to help deter them.

Are Wasps Good for Anything?

Yes, believe it or not, wasps are good for something–natural pest control. Wasps prey and feed on other pests including flies, caterpillars, beetles, and greenflies from otherwise damaging crops and gardens.

What are Wasps Attracted to?

When wasps are looking to establish a nest, typically in spring, they look for a spot where they’ll feel safe. Some wasps will build nests in trees, wall voids, and eaves while others will build nests in the ground and under decks. It all depends on the species.

Another factor in what attracts wasps is the season. In spring and early summer, wasps are attracted to protein. In late summer, wasps are attracted to sugary substances like soda and fruit. Because wasps are starving this time of year they also tend to be more aggressive. In fact, it’s not uncommon for yellow jackets to prey on honey bees and their hives.

Preventing Wasps

As with any pest, exclusion is the best defense against yellow jackets and hornets. If they don’t find your property favorable, they won’t nest there. Below are some steps you can take to help prevent wasps.

  • Ensure your trash is tightly sealed
  • Replace damaged or missing window and door screens
  • Ensure all gaps and crevices are sealed off (consider a silicone-based caulk)
  • Don’t leave pet food outside
  • Cover your exterior vents with wire mesh
  • Harvest ripe produce
  • Keep bright-colored flowers away from your home

Experts in Wasps

Wasp stings are painful and unlike honey bees, wasps can sting multiple times. These stinging insects release pheromones when they’ve stung and when they’ve been squished to signal danger to their colony. One wasp can quickly make a situation dangerous.
