I've been using the Nassenheider Evaporator to deliver formic acid in early August for a few years. Works well, but this is a back yard operation, so the considerable labor in preparation is not a big deal. I started with Oxalic Drizzle in mid-December this year. So far, I've seen good mite drops and I haven't lost any colonies yet. I'm considering adding a second annual formic treatment in September next fall if the weather holds. This is NW WA, so weather is never reliable. In recent discussions, formic delivery in Dri-Loc 50 pads came up. Can somebody explain how the pads were prepared, what strength formic, how long the treatment lasts and how many applications are needed for a complete treatment? Can't seem to get to any information online. A short description or a link would sure be appreciated. Thanks.
