GETTING RID OF CARPENTER BEES
What is a Carpenter Bee?
Carpenter bees are those pesky dive bombing bees around your house, fence, or decking in the spring months when they are nesting. They look like bumble bees.
What are Carpenter Bees Good For?
Carpenter bees are beneficial in that they pollinate flowers. Should you kill carpenter bees? Absolutely not, unless they are damaging your property. Only go after the ones around your house, fence or deck that you are having trouble with.
What Damage Caused from Carpenter Bees?
Carpenter Bees will nest in the spring, so the female carpenter bee will start a hole in wood about 9mm size then up about 2″ and then angle with the lumber. These bees return every year and will add on to the existing chamber eventually doing extensive damage.
Will Pressure Treated Lumber Kill Carpenter Bees
No! Unlike carpenter ants and termites which actually eat the wood fibers as a food source, carpenter bees chew and spit out the wood… never digesting the poison in treated lumber.
How Do I Know I Have Carpenter Bees?
In the spring, you will see what looks like bumble bees hovering and dive bombing on trespassers. If you see small piles of sawdust, look up for small 9mm size holes (like someone drilled a hole) for the nest entrance.
Will Carpenter Bees Sting?
Female carpenter bees will sting you if provoked enough! The male carpenter bees are the protectors and will buzz around and dive bomb on you, but they don’t sting.
Getting Rid of Pesky Carpenter Bees NATURALLY – no pesticides
Well, you can stay outside with badminton rackets and swat at the dive bombing carpenter bees but smart money is a 3 step process. First purchase a carpenter bee trap (or you can make one with scrap wood) at local flea markets and nursery centers. Cost is about $9 to $20 per trap. How the trap works – all four sides of trap (looks like birdhouse) have 9mm holes angled upwards with a plastic bottle inserted upside down in the floor. Hang the trap up high where you are having activity. Bees enter the hole, get bored and follow the light thru the bottom and cannot get out of plastic bottle. Empty the trap – take off cap and shake out.
Step 2 Purchase some food grade Diatomaceous Earth from local stores. This is natural and is made up of very small jagged crushed shells, which cut thru an insect’s exoskeleton when walking over it. Once the damage is done the insect dies. Take the food grade Diatomaceous Earth and spread it in the nesting hole to catch the remaining Carpenter Bees entering and exiting.
Step 3 After all activity ceases (give it a few days) then seal up the hole with caulking, wood putty, wood dowel, etc to keep next years carpenter bees from nesting in existing hole.
That is all there is to it, natural and no pesticides!
