If you’re noticing more wasps too close for comfort in your outdoor living spaces, or even invading your home, it might be time to solve your wasp problem. Whether they’re hiding between the vinyl in your eaves or building a nest under your covered porch, you need a powerful wasp spray to put an end to this winged assault.

The best wasp spray will kill on contact and from a safe distance, keeping the user out of harm’s way as they perform their grim job. These potent pesticides use a blend of neurotoxins that attack a wasp’s nervous system, rendering it paralyzed on contact. When sprayed into a nest, the substance will coat the hive, killing wasps returning to the hive hours later.

If you need a solution to your wasp problem, read on to learn which type of wasp spray is right for your home, and don’t miss our list of some of the best wasp sprays you can buy.

  1. BEST OVERALL: Raid Wasp and Hornet Killer, 17.5 OZ (Pack of 3)
  3. BEST SPRAY CAN: Spectracide Wasp and Hornet Killer 20-Ounce 2-Pack
  4. BEST CONCENTRATE: Syngenta 73654 Demand CS Insecticide
  6. BEST ORGANIC INSECTICIDE: EcoSMART Organic Wasp and Hornet Killer


Types of Wasp Spray

While most wasp sprays use the same chemicals to perform their job, sprays come in three forms.


Wasp sprays contain powerful pyrethroids and pyrethrins that will effectively paralyze a wasp on contact, preventing it from retaliation by stinging the user. These sprays allow you to stand a reasonably safe distance of up to 27 feet away, reducing the odds that you’ll be stung. As wasps tend to make their nests in the eaves of your home, this long range allows you to reach the nest without having to use a ladder, which could be dangerous should you need to make a hasty retreat.

Of course, blasting a nest from 27 feet away takes some skill. The further away you are, the harder it is to aim the spray accurately, causing waste or, worse, leaving enough wasps alive to mount a counterattack.

A thorough approach works best when using a spray. A few spurts aren’t enough. Keep the nozzle depressed and coat the entire nest to ensure all wasps are disabled to prevent any from retaliating or escaping to build a hive in some other location near your home.

Aerosol Foam

Aerosol Foam sprays work similarly to standard sprays, only the liquid creates a foam on contact, trapping the wasps, then paralyzing them with chemicals. The foam expands after it hits a nest, increasing the pesticide’s coverage and ensuring fewer wasps escape. While aerosol foams provide better coverage than standard sprays, they have shorter ranges of up to 20 feet.

Liquid Concentrate

For smaller problems, a simple can of spray or aerosol foam will get the job done. Unfortunately, wasps can be persistent pests, returning to make nests in various nooks and crannies around your home’s exterior. If you have a recurring wasp problem, you may need a large supply of wasp killer on hand to keep the wasps at bay. One bottle of liquid concentrate can make up to 40 gallons of spray, offering a much better value than the spray-ready products. Concentrates are also typically effective against a broader range of insects than canned sprays, allowing you to take out ants, roaches, and a whole host of other pests.

Concentrates do have their downsides. You must mix the concentrate with water before using it, which can be a hassle. You’ll also have to purchase a sprayer to apply a liquid concentrate once mixed. A liquid concentrate pesticide also won’t have the same range as aerosol because it is not compressed in a can. This means you’ll need to stand much closer to the nest when applying the pesticide, making you more vulnerable to stings.

The products below kill wasps on contact, with most allowing you to remain at a safe distance when doing so. This list includes some of the best wasp sprays from the most well-known names in pest control.

Best Concentrate


Syngenta 73654 Demand CS Insecticide



For those recurring wasp problems, buying individual cans can become cumbersome and costly. You may prefer to have a lot of pesticide on hand.

There are some trade-offs for the value this spray offers. You need to purchase a sprayer to apply this product. It also requires you to mix the concentrate with water before using it.

Best Foam

FAQs About Wasp Spray

If you’re wondering how you should use wasp spray, how these products kill insects, or whether they’re harmful to humans, read on for answers.

Q. How do you use wasp spray?

Use the following steps to put an end to the wasps invading your home:

  • Wait until sunset. While this may sound dramatic, it’s actually strategic. These insects are least active at dusk, meaning most of the wasp population will be in the hive, maximizing your ability to eliminate all of its inhabitants.
  • Stand safely away from the nest. Wasp sprays are designed with ranges of 15 to 27 feet for a reason. When you spray the hive, the wasps will attempt to counterattack. The farther you are from the hive, the safer for you. It’s also important not to stand under the nest, as the spray will run off of it and fall to the ground along with any six-legged casualties.
  • Soak the nest. Don’t be stingy with the spray. Dousing the nest will ensure that you kill all the wasps, preventing them from coming after you. A nest soaked with pesticide will also take care of any inhabitants that return to the hive later.
  • Wait 24 hours. Even if you plan your attack at sunset, it’s unlikely every wasp will be at home. Wait 24 hours before removing the nest to allow the pesticide to kill any wasps returning to the hive.
  • Dispose of the nest. Remember that most pesticides are hazardous to humans and pets. Wear gloves and a mask when removing the wasp nest. Make sure to put the nest in an enclosed garbage can to prevent pets and children from coming into contact with it.

Q. What does wasp spray do to a wasp?

Wasp sprays use chemicals known as pyrethroids and pyrethrins, both of which cause catastrophic damage to the wasp’s nervous system on contact, paralyzing them and then killing them. This is why a wasp will drop out of the air instantly after being sprayed.

Q. Is wasp spray dangerous to humans?

Wasp spray is dangerous to humans. The National Pesticide Information Center warns that brief direct exposure can cause symptoms that include difficulty breathing, headaches, dizziness, nausea, vomiting, abdominal pain, itching, or burning. Always use caution to avoid skin or eye contact, do not breathe it in, and do not ingest wasp spray. But if an accident happens, contact a Poison Control Center. Should symptoms be concerning, seek emergency medical help immediately.
