Problem: mason bees going into old tubes
” Hi & thank you for your response to my prior eMail of several weeks back. Now I have another question. First I have some good news. It seems most of my bees had not hatched from their tubes before the cold & stormy weather hit us. Today there are lots of bees near the tubes & in my garden too! There is a lot more debris below the tubes which means many bees from deeper in the tubes have made their way out – mostly females to boot!
Now the question: The bees are going back inside the “used tubes”. Will they re-use the old cardboard tubes or is there another reason they continue to enter last year’s tubes? Should I remove the tubes? I have 2 of your houses with the colored Eco-Quicklock blocks. I’ve added paper liners to about 20% of the holes & will see if the bees have a preference for the lined holes. Bees are beginning to use the houses but it’s too early to tell if there is a preference.
Thanks for your attention.”
