Wasp Spray vs Bear Spray

With the recent surge in violent crimes, and the ensuing air of panic and helplessness, hoaxes aimed at pranking people desperate for protecting themselves and their loved ones have sprung from thin air. One such hoax claims that wasp spray can be used as a replacement against pepper spray products, for instance, bear spray.

As an outdoorsman who has to spend a small fortune on bear repellent each year, I was tempted to explore the possibility myself. Having conducted a lot of painstaking research on this wasp spray vs bear spray debate, I share my discoveries with you to help you make the smart decision.

At A Glance

  • Key ingredient pyrethrin, poisonous
  • Chances of permanent damage to attacker
  • About 20’ range
  • Relatively inexpensive
  • Mostly illegal for domestic and wild life self defense
  • Unproven effectiveness
  • Key ingredient capsaicins, not poisonous
  • Only temporary debilitation of the attacker
  • 20’+ range
  • Pricey
  • Mostly legal for domestic and wildlife self defense
  • Effectiveness proven by research and trial

Facts About Wasp Spray


Most wasp sprays have pyrethrin as their active ingredients – these are chemical derivatives taken from a chrysanthemum plant species that will target the nervous system of the wasp, hornet or other insects to neutralize it. However, wasp sprays have not been directly tested against humans, so their effects are as yet unknown and they cannot be relied upon for effective non-lethal self-defense.

There is simply no way of telling, as yet, whether the toxic nature of pyrethrin will be more or less harmful to humans than is touted by some self-proclaimed ‘experts’.

Proponent’s Perspective


Those who advocate the use of bug spray as a substitute for bear spray claim that it is both cheap, and easier to aim over a considerable range. They are right in both regards, since the product is indeed inexpensive compared to bear deterrent, and it is far more precise than bear repellent.

Inexpensiveness aside, the precision can be a two edged sword: while it certainly makes small work of bugs, trying to aim carefully at a bear’s face while it charges at you could turn into a lesson in futility that none of us would want to learn.

Legal Considerations


Furthermore, lots of jurisdictions have made it illegal to use non-pepper spray products for self-defense – this includes wasp killers. In fact, you’ll find explicit warnings on most insecticides and pesticides, stating that using them in a manner other than specified on their label is a violation of federal law.

And if you’re thinking that it won’t be a big punishment, since you’re only using it for protecting yourself, remember that wasp spray is essentially a poison, and consider this example taken straight from the Oklahoma state legislature.

§21651. Poison, attempt to kill by administering. Any person who, with intent to kill, administers or causes or procures to be administered to another any poison which is actually taken by such other person but by which death is not caused shall be guilty of a felony, punishable by imprisonment in the State Penitentiary not less than ten (10) years.

In simple words, you could end up serving a ten year sentence (or greater) if you poison someone by spraying bug spray on them inadvertently and, perhaps even deliberately for the sake of defense! Most other states in North America enforce similar penalties.

Facts About Bear Spray


The active ingredients in bear deterrent are derivatives of capsaicin, the stuff responsible for giving chili peppers their fiery flavor. It also contains oleoresin capsicum, which is also present in all other pepper spray products. Basically, the effect of these core ingredients is to temporarily debilitate the aggressing party by inflaming their eyes, nose, and skin – resulting in a loss of sight, smell and breath, as well as burning pain.

Proponent’s Perspective

Canisters of bear spray with a range equivalent to or greater than that of wasp spray are readily available, and they work by creating a cloud of fiery OC derivative that can stop a large animal / human dead in their tracks. This method of self-preservation carries no risk of poisoning, for the attacker or for the would-be victim.


The effectiveness of bear deterrent at stopping attackers has been well documented and researched over several decades of use, which is why it is recommended as a suitable self-defense product against bears and other large animals by several wildlife agencies and independent researchers.

Legal Considerations


In Canada, you can’t use (or keep) bear spray for use against humans – it is against the law. I’d still recommend sticking with another pepper spray product over wasp spray though, for reasons discussed before.


Now that you’ve got a clear idea about the difference between bear spray and wasp spray, I’m sure you will agree with me that it is a capitally bad idea to forego bear repellent (or any other pepper spray product for that matter) in favor of wasp spray. Wasp spray is poisonous, and it is a largely untested hazard against humans (because it hasn’t been designed for use against them); not only does this make it illegal to use for the sake self-defense against humans in many states, it also makes it dangerous for the wielder, in case they misfire and hit themselves instead of the assailant.

Bear spray, has a proven track record of effectiveness against bears, as well as many other large animals, check out our list of the best bear spray. While there hasn’t been any significant research on its effectiveness on humans, the fact that it shares a large part of its composition with regular OC spray, combined with plenty of anecdotal accounts of its success against human attackers, indicates that it will definitely be more effective against humans than wasp spray. Besides, it won’t cause any lasting harm, to the attacker or to yourself (in case you misfire in the heat of the moment).

Just remember that bear deterrent, if used indoors and in close quarters, could cause some painful inconvenience for the wielder themselves, and will definitely make the room it is used in non-habitable for quite some time!

  1. You have a right to defend yourself with a gun witch can kill someone rather quickly ! Hell if someone breaks into my house he’s going to the morgue ! Hell if its a 12ga. 00 buck or wasp spray !

  2. What about the pepper mint oil wasp spray that shoots a long distance and will burn and distroy pretty much anything including the user if not careful?

  3. Comparing the MSDS and Safety/Chemical of both Hornet Spray and Bear Spray…No difference in the response of the irritation of the sprayed animal However the hornet spry can be aimed better. With Mist Bear spray…far less than 1% gets into eyes or nose while with an aimed foamed jet of Hornet spray you can get 50% or more into the eyes, nose or throat. Thus far more success possible. I just had ( 7/14/2018) my person experience with a male bear and bear spry at 15 feet. I enveloped the bear in a cloud of bear spray mist. The bear ignored it!!!!!!
