Used in monitoring and fighting against varroa infestations, our varroa screen is placed on top of a regular bottom board. A certain percentage of varroa mites will accidentally fall off bees or out of the hive when transferring from bee to bee.With just a bottom board in place, the fallen mites will just hitch a ride on a bee entering the hive. When a varroa screen is on the hive, the mites will fall through the screen and onto the bottom board. Because the front entrance to the bottom board is closed off, it forces the bees to enter above the screen and keeps mites trapped on the bottom board, where they consequently die. Researchers indicate that mite fall may be as high as 30% .
1. Extra Wide 4-3/4" entrance board
2. Can be used without bottom board also - debris will just fall on the ground
3. Ideal for IPM of Varroa - by using our white tray or a sheet of heavy, white cardboard, you can closely monitor the mite fall when using miticides.
4.Plastic rims are available. They are added to varroa screens to support varroa trays when used on hive stands without a solid bottom.
Hint: If you reverse the bottom board and have the old entrance facing out the back, you can do your monitoring from the back of the hive.
Dimensions: 22” x 14” x 1-1/2”
