Does wasp spray kill carpenter bees?

If you have carpenter bees and want to know if wasp spray will kill them, the answer is yes! Wasp spray is a great way to get rid of carpenter bees and prevent them from coming back. You can use wasp spray indoors or outdoors, depending on where your carpenter bee problem is.

The reason that wasp spray is so effective against carpenter bees is that it contains pyrethrum. This natural substance can kill insects and other pests without harming humans or pets. It’s also non-toxic, which means you don’t have to worry about any harmful side effects from using it around your home or yard.

How does wasp spray kill carpenter bees?

Carpenter bees are social insects, so it’s important to eliminate their nests. If you can find the nest and spray it directly with insecticide, this will kill a large number of carpenter bees.

If you don’t know where the nest is, spraying around your house will also kill some carpenter bees but not all of them. They’ll be confused by the scent of wasp spray and may not return to their nest for a few days or longer. This gives you time to find the nest and destroy it before they return in force!

The best way to kill carpenter bees is by using insecticides. You can use either a spray or dust, but make sure that the product you choose is labeled for carpenter bees.

Will WD-40 kill carpenter bees?

WD-40 can kill carpenter bees, but it’s not the best insecticide for the job. It will kill some bees, but if you’re looking to get rid of carpenter bees quickly and efficiently, WD-40 isn’t your best bet. However, there are other types of spraying products that will work better than WD-40.

Instead, try a spray or dust insecticide that’s labeled for carpenter bees. You can find these products at most hardware stores or online.

How destructive are carpenter bees?

For the most part, carpenter bees are not aggressive and will only sting you if you threaten them or their nest. They do not eat wood, so they don’t cause any structural damage to your home.

If you see a carpenter bee flying around your house, it may be looking for a place to start its new home — but as long as your house is well built and has no holes in it that could be used as nesting sites, there isn’t much chance of being bothered by carpenter bees.

How to safely kill carpenter bees?

There are a few steps you can take to safely kill carpenter bees.

  • Keep children and pets away from the area where you are spraying. They could get stung.
  • Wear protective gear, such as gloves and goggles, when spraying your nest to avoid getting stung yourself. If you can’t find any protective gear, cover up with long sleeves and pants before going near the nest or sprayer.
  • Use a hand pump sprayer instead of aerosol cans if possible because they contain more product and will last longer than an aerosol can would in this situation (spraying carpenter bee nests). Another option is using a hose-end sprayer; it’s easier to control how much of the product gets sprayed out at once when using this method rather than holding down the trigger button continuously until all of the wasp spray has been used up (which could take hours depending on how large your nest is).
  • Spray from a distance—at least 10 feet away—so that there’s less chance for accidentally getting stung by one of these pests while trying to kill them off!

What other sprays can I use to kill carpenter bees?

When it comes to carpenter bees, WD-40 is not the answer. If you’re looking for a natural way to get rid of these pests, we recommend using products that are safe around children and pets—and non-toxic in general.

Some options include:

  • Insecticides containing pyrethrins (Pyganic Natural Insecticide), bifenthrin (Talstar P) or lambda-cyhalothrin (Scimitar). These sprays work quickly and can kill bees on contact or by ingestion; however, they do tend to have an odor that may be unpleasant for those sensitive to smells. Pyganic is also available as a dust formulation if you want something less messy.
  • Orthene 0.5% dust—the active ingredient in this product kills carpenter bees when ingested or contacted on their bodies directly; however, it should be noted that some people have reported cases where wasps have been able to withstand treatment with this chemical due to its relatively low concentration level compared with other insecticides like Cyper WP which contain 2% permethrin instead.
  • Another option for treating carpenter bee nests is to use Tempo Dust, which is available at many garden supply stores. These dusts work by contact; they do not kill the bees on contact like sprays can, but instead need to be ingested or contacted directly by their bodies in order to take effect.


As you can see, there are a number of sprays that can kill carpenter bees. The most effective way to get rid of them is by spraying the nest directly with wasp spray or WD-40 and then waiting for the bees to die. 

However, if you don’t want to use any chemicals then another alternative would be natural essential oils like peppermint oil which repels insects away from your home.
