Using Apiguard with SBB

[luka]

I've heard that when using Api-guard or other thymol products that the screened bottom board has to be closed
Is this so and if so how is the SBB board closed?

[Hawkster]

i just insert the sticky board in which effectively closes the screen

Scroll down to "Testing MAQS in California", and take a look at the bar graph of his results. He got good mite kill on screened bottoms with both MAQS and Apiguard.

[Hawkster]

yes and he has left the sticky board in the SBB

If your screened bottom board did not come with a corrugated sheet to slide underneath you can buy one or make one. You can cut a piece of cardboard so that it slides underneath you sbb and blocks airflow. It won't fit tightly to the bottom but will work well enough.
