I am still building my screen bottom boards(as well as my new house, so you can see why I am a little behind), but I am all set up to use the FGMO fogging system. Is it worth using the fogger without the screen bottom boards in place? I understand that if the mites drop off the can climb back on the next bee that walks by, but if this could also works for T. mites than I don't have anything to lose. If the mineral oil actually kills the V. mites then obviously the screen bottom board is not a nessesity(sp). Just looking for some advice. Thanks in advance. David
