So iddee, you think it's just defective? I was hoping to see a comment from someone else who's used this model with or without problems. My problem for now though is, I need to collect pollen every two weeks for a study, and I'm afraid if I send it back I won't have a replacement within two weeks, so I'll just have to live with it till the study's over in the fall.
This week I collected on a hot day, taped the top again to make sure it wouldn't warp in the heat, and when I went out in the evening to pull the tray it was chock full of bees. They were also hanging all around the outside (top, bottom, front and back), and boy were they mad when I pulled out the tray. I've learned I have to dump the pollen and bees into a colander and sift out the pollen, which makes them madder still.Then I can't snap the trap into the open position without smashing bees, so I have to just put a stick in to hold it partway open. What a pain!
