I have another issue, yesterday both male and female were in and out of box building a nest and when we looked inside it was a very nice nest in process, but after I seen both this morning on the top of house then leaving and hadn’t come back all day that I could see, I opened the box a few minutes ago and seen a wasp had started a small nest hanging inside on the top of the box and I removed it but now afraid that the birds have moved on. Has anyone ever had this issue and what is the results? Should I just take out the nest and cap the door and wait to try again next year? I feel so bad I didn’t catch this sooner.
I thank the persons who answered my 1st post about my dog, was so glad the B birds don’t seem to mind, but now a wasp issue.
The wasps nest has to go. Best way to get rid of it is to do it after dark. Use a flashlight and a stick. Open the nestbox and using the stick mash the wasp nest and scoop it out. Do NOT spray insecticide in the box as this will harm or kill and birds that use it. Just wait until after dark. Wasps are inactive after dark so you are less likely to get stung if at all. After you remove the wasp nest take a bar of soap and rub it on the inside of the roof where the wasps put their nest. This should prevent them from building a nest again.
