These sticky boards can be used with or without the screen to monitor or diagnose a mite infestation. 
When placed directly on the bottom board, a screen will be needed to keep the bees from sticking to the adhesive.
Use in conjunction with a screened bottom board as part of an IPM strategy.
This sticky board is conveniently printed with grid lines to aid in determining the number of mites that are present.
