How do you know when you have a carpenter bee infestation, and what should you do?
Do you see the stain on the aluminum siding?
That is a sure sign there was a carpenter bee infestation in the past.
It might be current and active.
Sometimes I see 10 or 20 of these stains all along the underside of the fascia board along a roof.
These stains are created by carpenter bee spit and vomit.
If you clean it off and smell your rag, it smells like honey!
Well, of course! What do you think honey is?
Here is what a carpenter bee hole looks like.
Carpenter bee holes all look the same.
They are very round and about the size of your pinky.
The bees create a hole in the wood and then tunnels to the left and right. At the end of the tunnel they lay eggs. Then they drag in some form of food for the eggs when they hatch - another insect or two. The carpenter bee then dies leaving the next generation to happen.
The next generation will do exactly the same thing. Over time you can have quite an infestation! And your wood can become very damaged.
When I see the holes (they happen on our daughter's wooden play set in the rear yard) I do this:
1. Spray in some insecticide
2. Fill the hole with caulking
When the bee returns home it sees all that, and gives up to go find another house to infest! Often carpenter bees pick out a house in a neighborhood and go at it! You have to pay attention to the stains and when you see them go into action yourself!
A carpenter bee looks like a bumble bee, but with a slightly more pointed hind end.
That image is just about life sized!
When you see them flying, often they will stay still in the air, especially as they examine something, like the side of your house! Once they find the perfect spot, they will go after it. They can create a hole in short order!
My recommendation: when you see the stains it means a hole is being worked on or already created. You should eliminate the bee's desire immediately. Spray the hole and fill it. That will quash the bee's desire and it will move on.
