Hi Bill ― a few years down the road now from this post. Are you still using oxalic in this method and what kind of results are you seeing? Thanks.Remember to treat the hives in the fall after the supers are pulled just to be on the safe side, it has been said that Oxalic can be applied with the supers on but I just do not want to take that chance.
Why mess with something that works ? It's only on for 3 minutes or less. I've had excellent results with mine... no mites!Like the looks of it. I read modern glow plugs heat up to 1000 degrees, would a 350 thermostat in series with glow plug affect it greatly.
