Quite the Dewitt contraption Allen - I like it!  I'm wondering what the power source is for the fan and vaporizers.  We found that burning efficiency of using batteries degraded quite rapidly when using several vaporizers.

We used a hokey dokey kind of setup with the Vaporizers powered by a battery charger which is powered via a generator in the back of the pickup.  Each vaporizer draws 12 amps as I recall, so we had one 35 amp charger and a smaller one for use with four vaporizers.   Still too slow for my liking.

Clearance was not a problem as we treated via the bottom drawer of screened bottom boards by replacing drawer with one modified to hold the vaporizer and contain the escape of vapor.

Still wondering why one poster here had 0 efficacy with vapor.  Type of oxalic used perhaps?

In sunny New Brunswick Canada, where the bees were hauling water today.  Earliest I've seen in 25 years...
