Will Soapy Water Kill Carpenter Bees?

You’ve seen them. They’re hard to miss. The carpenter bees buzz around your garden and home, looking for a place to bore into wood and make a nest. These pests pose an enormous threat to untreated wooden structures and other unprotected wood, but fortunately, there is a simple solution: spraying them with soapy water!

Carpenter bees are attracted by the smell of fresh sap from cut or wounded trees or other wood sources such as decks, fences, siding, etc. They drill holes about 1/2 inch in diameter in order to lay their eggs inside the wood structure where they can be safe from predators and parasites. When you see these pests buzzing around your house or garden – it’s important not just to shoo them away since they can sting– but to take preventive action against future infestations since they are most likely actively looking for a new nest. Along with this, carpenter bees aren’t simply seasonal insects, they have a long lifespan which means you want to deal with them in an effective manner.

Will Soapy Water Kill Carpenter Bees?

Yes, soapy water will kill carpenter bees. When carpenter bees are sprayed with a soapy water mixture, it makes the mixture thicker and more viscose than water, which coats the carpenter bee and prevents them from breathing through their skin, and eventually suffocates them.

Killing Carpenter Bees Using Soapy water

There are basically two ways to use soapy water for killing carpenter bees:

  1. Mix a solution of 1 part dishwashing soap to 5 parts water in a spray bottle, and apply it using direct-spray methods.
  2. Mix 2 tablespoons of dishwashing soap with 1 liter of water, and place the soapy solution in a watering can. Drench the wood with soapy water to kill carpenter bees and their larvae.

The soap breaks down the wax coating on both eggs and adults, causing them to dehydrate and die. How long it takes for the carpenter bees to die depends on how soon after they’re sprayed they are able to reach water that will wash away the soap. If you can get them to drink and coat themselves with the soapy water faster, they’ll die sooner.

To guarantee you kill any carpenter bee larvae in their nests before they have a chance to mature and hatch, apply the soapy water twice at two-week intervals. This ensures there won’t be any survivors.

Other Methods Of Getting Rid Of Carpenter Bees

There are also other ways to use soapy water for killing carpenter bees, but the one presented here is by far the simplest and most effective that has been proven to work time after time. Other methods include spraying soapy water through drilled holes in the wood, or filling a caulking gun with soapy water and injecting it deep into the drilled entry hole. However, be careful with these procedures to avoid damaging a structure by drilling holes in it or pushing soapy water too far into the wood.

Do-it-yourselfers have great success using this method for killing carpenter bees on their homes and other structures made of unpainted wood. It’s best to spray the soapy water on a day when temperatures are above 60 degrees Fahrenheit and wait at least a couple of days to allow for maximum penetration of the wood.

In order to keep carpenter bees from making nests in their structures in the future, it’s important to inspect the exterior of wooden structures every spring for signs of fresh wood shavings or drill holes. If any are found, immediately apply soapy water to the area using the methods described above.
