Behavior: Where Do They Hide in Utah?

  • Dangling LegsYou can identify a paper wasp in flight because their long back legs dangle down beneath them.
  • Beneficial PredatorsThey are actually great for Utah gardens! They hunt caterpillars and garden pests to feed their larvae.
  • Defensive, Not AggressiveThey usually only sting if you get within a few inches of their nest or accidentally swat at them.

Frequently Asked Questions

  • Should I knock the nest down myself?Unless the nest is in a high-traffic area (like a doorway), they are often best left alone. If you must remove it, do so at night when they are less active, but professional removal is always safer.
  • Will they return to the same spot next year?Wasps do not reuse old nests, but they often choose the same "perfect" corner of your eaves. Removing the old nest and cleaning the area is key.
