I purchased oil pans and they would not fit on my bottom boards! This company said this might be the case so I ordered new bottom boards for my 8 frame hives. I saw these used with our bee club hives and I was impressed! It has rained since I received them however I did get one installed. I’m looking forward to getting all of them installed so I can monitor my hive beetle and varroa mite counts since I did a mite treatment the last part of July. Thanks to Foxhound for making the oil pans available and helping me figure out how to get everything put together.
