There is no way to keep them away. However, you should fill the holes that they leave with wood putty to assure sound structure. Sorry I know they can be a pain.
Thank you, wil try Saw a Wood bee trap out of Oklahoma, might try.
Thanks for the answers,
The bees are coming back to the same location due to hatching in that area. You need to kill off the larva by filling the holes with chemical dust and sealing off with wood putty. A good quality paint covering any exposed wood will stop them from re-boring into the wood. If the damage is occurring along the rake trims, (wood that runs along the edge of the roof line) the wood was not painted or was very poorly painted when it was installed. Filling those gaps between the siding and back side using a slow expanding spray foam followed with a good quality paint will do the trick. Or simply hire a pro to dust behind the boards and after several cycles of the bees coming back you will eventually kill them off. However if your neighbor also has this same issue, you will be having this issue for a long time.
For damage that has already occurred you can use wood putty or we use automotive plastic filler. It dries faster and will last a long time. Sand smooth and paint.,
Thank you so much...will try all of the above. Thank you.
What is automotive plastic filler...Think I know what you meant but not sure
Auto plastic filler is used to fix dents in autos. IT is a two part product in which you mix. The result it gets hard within 10 min or so once mixed. IT can be sanded and drilled once it fully hardens. You can find this in the paint section of most home improvement centers in qts and gallon sizes.
Happy to say NO WOOD BEES in 2 wks....YAY!!!!
Chemical dust like Woodbridge says. I had a bad case of them down in VA.
