The Top 5 Wasp Sprays

Wasps are important pollinators that play a key role in their native ecosystems. Unfortunately, these insects also have a knack for wandering into unwelcoming territories, namely screen-in porches, sheds, and treehouses. In such cases, you might want to consider a wasp spray to help eliminate the threat. These products shoot a jet of neurotoxins that disrupt the nervous system of whatever inhales them. If they sound deadly, that's because they are - to wasps. In fact, insecticides such as these are contributing to a global collapse of pollinators. Thus, we urge folks to use these products sparingly and only as a last case resort. Here, we list the top five wasp sprays, from the best at a distance to the best on a budget.

EcoSmart Wasp & Hornet Killer 14 oz. Aerosol (2-pack)

The plant-based killer

Plant-based and safe to use around children and pets, this 2-pack from EcoSmart kills Wasps & Hornets using a non-toxic and environmentally-friendly formula.
Best Non-Toxic

Find on Amazon

It’s reasonable to be wary of the neurotoxic chemicals of most wasp sprays, especially when using them around young children and pets. That’s why EcoSmart invented a wasp and hornet killer that’s plant-based, environmentally-friendly, and safe to use around children and pets. Rather than using inorganic concoctions to eliminate pests, this option employs peppermint oil, wintergreen oil, and canola oil in its fight against wasps. Surprisingly, it’s an effective spray when used properly and liberally. Better yet, it also works as a repellent, so any stragglers are unlikely to return. Who knew wasps hated peppermint?


  • Surprisingly effective
  • Decent, 18-foot range
  • Plant-based ingredients
  • Non-toxic to pets and people


  • Requires a lot of spraying for lasting results
  • Expensive

Spectracide 100046033 Wasp & Hornet Killer3 (Aerosol) (HG-95715) (20 oz)

More spray for your buck

Tried-and-true and as simple as could be, Spectracide is an extra-large insecticide that comes in an ample, 20-ounce can.
Best Value Size

Find on Amazon

Waging war against wasps and hornets sometimes takes a little extra ammunition. For those looking for an insecticide with some extra juice, we recommend this 20-ounce can from Spectracide. It’s a large supply that can easily take on numerous nests. Better yet, this option sports one of the longest distance sprays on the market, with a reach of up to 27 feet. That being said, it’s best for nest control and not for spraying onto individual wasps. Soaking a nest is an effective way to eliminate a wasp problem, but this option doesn’t kill on contact quite as quickly as the other options. That being said, it’s perfect for the spray-and-pray approach, since the reach is so long and the volume is so large.


  • Large, 20-ounce volume
  • Super-far, 27-foot range
  • Great price


  • Doesn’t kill on contact

Best Multipack

Find on Amazon

When one can isn’t enough, you might need two. Heck, why not just get three while you’re at it? A popular pick among those with large properties, such as farms and country houses, this 3-pack from Raid is the ideal solution for taking on multiple nests. It has all the features that we look for in a wasp spray, such as a long range, a fast-killing formula, and a high accuracy. Better yet, the nozzle is designed in a way that reduces blowback during spraying. It’s another great overall option that conveniently comes in a pack of three. And although the price might seem kind of steep, it’s worth it for those looking for a tried-and-true product from a well-known company.


  • Super accurate
  • Kills quickly on contact
  • Comes in pack of three


  • Kind of expensive

Frequently Asked Questions

Are there alternative ways to take care of wasps?

For the brave of heart and the allergy-free, there are a number of ways to kill wasps or deter them from nesting around the house. One popular method is to douse the nest in hot soapy water. Make a 1:3 solution of liquid soap and near-boiling water. Using a spray bucket with a high-pressure nozzle, douse the entire nest. The soap corrodes the wasps’ exoskeletons and wings and the water drowns them.

In order to deter wasps, there are ways to trick them into believing that the territory is already occupied. For example, you can buy nest decoys to hang in the areas in which wasps are most likely to nest. It may sound ludicrous, but many people have found success in this way.

Will these kill bees?

These sprays will absolutely kill bees. We strongly discourage using these products on bees or near bee populations. Honeybees in particular are a keystone species that’s responsible for pollinating flowers and fruit trees. Without these essential creatures, many plants will go the way of the dodo bird. In fact, insecticides are currently causing a global collapse of honeybee populations. That’s why we only recommend the use of wasp sprays in instances where the animals are forming their nests against houses and other frequented structures.

Are these safe around pets?

Other than the plant-based non-toxic option, all of the picks on our list contain neurotoxic chemicals that are dangerous to pets and people. Always aim the spray away and downwind. After a nest’s inhabitants have been destroyed, dispose of the nest in a trash can and wash off the chemical residues with a hose.

What if I’m allergic to stings?

Those that are highly allergic to bee and wasp stings should not attempt to use these sprays. Spraying a nest can trigger the inhabitants to defend their home from you, the attacker. Ask a relative or neighbor to spray the nest and remain indoors until the threat has been eliminated.
