Great video, I really enjoyed it. Thank you for the top quality content. How do the parasitic wasps access the egg chambers? Do the wood tray style houses reduce the occurrence of wasp invasion vs the paper tubes?
Crown Bees is my source for Mason bee supplies and advice. They have been so helpful! I've been "growing" Mason bees for years and years and they are special and very gentle. They can sting but I have walked right into a "swarm" of them... kind of atypical... and never been bothered. If you can raise Mason bees, do so.
When you say store them mud face up do you mean as pictured in your slide or actually mud facing up? Just want to ensure the most for my baby bees! First year I’ve gotten the bees to stick around and I’m really proud!
You can get out kits with reusable trays, just use the drop-down menu to pick the tray option. Here's our Spring Mason Bee Kit: crownbees.com/chalet-or-cottage-spring-kit-holiday-bonus-bees.html
I got my mud boxes from Crown - work great - just make certain you put the box out before the bees venture out so it will be used. Also got attractant.
