As I’m sure most of you are aware we have opted for including screened bottom boards as part of the full flow hive. Here is a good article advocating the use of screened bottom boards especially for the Australian climate.
They are great for helping control many pests. On top of the plastic board that you slide under the hive we have been using cheap plastic table cloths upside down (they have a fluffy felt like back on them) stuck there with double sided sticky tape. The small hive beetle fall through and get tired and stuck trying to crawl out, eventually dying. This method avoids using oil or water which can fester.
So it seems like only a good thing to use screened bottom boards in Australia. What are peoples thoughts on them for colder climates?
