They are in the eves of both the front and back of the house. I had asked the contractor to caulk up the holes when he did new siding and soffets on the house. He did not. Will I get the bees in the house in the spring as there will be no way for them to get out. I’ve asked that the back of the house holes be caulked.
If you read through our CARPENTER BEE CONTROL ARTICLE, you’ll learn these bees will use their nests all year. Additionally they’ll lay eggs in the nest and either late fall or early next spring, new bees will hatch looking to leave. If you seal these holes without first treating with DEMISE DUST, the bees will not be able to escape. In most cases they choose to drill around the caulking. This will cause new holes to form as well as allow for the possibility that some will drill in the opposite direction eventually ending up inside the home.
Additionally, even if you treated with the Demise and caulked the hole tight, the same thing would happen as explained here:
In summary, you should not caulk any carpenter bee hole or else you risk having them end up inside the home. Instead you should dust with Demise and then seal the hole with the 1/2″ CORKS we have listed in the article. This will allow hatching bees to get a dose of the Demise and die before they can emerge.
