arrived quickly and super handy

I ordered these a year ago and they were great. Unfortunately I reordered recently and the new ones don’t fit in the same outer tubes. They are just a smidge too wide. It’s almost indistinguishable to the eye but these new buggers will not fit in the outer tubes.

Good replacement liners for cardboard tubes by same company. If you are just starting out in helping wild bees, these may work ok by themselves, but are better inside the thicker cardboard tubes because parasitic insects drill through them to prey on the bee larvae. I had very few cases of that using them as liners.

Wish they were about half inch shorter to fit in the cardboard tubes. They can be cut, but it takes a while to trim all of them.

Bought these for raising Mason Bees, and they took right to them. Had to cut them to the correct length of course, and I even went the extra mile to use clay and plug one end of these straws for them - saved them the time to do that, and I was handsomely rewarded with a bumper crop of Mason Bee cocoons this year, So many full tubes this year, I am offering them to friends, and I also plan to be almost a modern day Johnny Appleseed, but instead go around and leave a few of these full tubes in safe dry spots around the county for them to hatch next spring and continue the cycle on the wild side. Our honey bees are having a tough time, and these super pollinators can do wonders to help them, and us out. Thank you!
