Wasps are dangerous and aggressive insects. They fly solo but also attack in packs. Wasps have a long stinger to attack and, unlike bees, they don’t die after stinging someone, and can go through a lifetime hurting numerous people. That’s why if you ever come into contact with a wasp or even a wasp nest, you must act quickly and eliminate them immediately. An aerosol spray is your best tool when fighting off these nasty insects, so here are some of the best sprays that will keep wasps and other insects from ruining your time outside.

Finding the Right Spray 

Here are some things to consider:

  • Versatility: Some of the best sprays that are intended for killing wasps also work for other insects such as hornets and yellow jackets. Be on the lookout for sprays that offer such versatility, as this will come in handy when you’re up against different types of insects invading your personal surroundings.
  • Powerful Spray: When we talk about power, we’re also talking about the trajectory of the spray and from what kind of distance can you safely attack a wasp and its nest. A jet spray that provides pinpoint accuracy from at least 20 feet is ideal. A powerful spray intended to kill the nest should also kill insects that return to it after a few days.

Now, let’s take a closer look at the best sprays to kill wasps.
