This spring I installed a screen landing pad in front of 2 hives trying to see if many mites droped off bees when they landed. I used a number 8 mesh screen sticking out 4 inches from the hives. I found that using a sticky board under it I traped many mites and a lot of pollon with them. The 2 hives that I did this to were only about 2/3 as strong in bees as the control hive. (probably due to lack of pollon)
All my hives are fogged weekly with FGMO and have cords changed every month.
I'll be gone for at least 1 week moving hives
south for pollonation contracts so will check back later
just South of Lansing Michigan
