HI I HAVE A PATIO COVER WHERE ONE OF THE FRAMED SUPPORT COLUMNS HAVE BEES INSIDE. THE COLUMN IS 2FT X 2FT 8 FT. THEY ARE HOLLOW INSIDE. WHAT TYPE OF SPRAYER /PRODUCT DO YOU RECOMMEND IN THIS TYPE OF CONDITION?
Bees and other pests will commonly take advantage of small spaces and voids like that which could be in a support column like the one you’re describing. For this application, the best approach is to make a small access hole and treat with some PYGANIC DUST. Using a small CRUSADER HAND DUSTER, you will be able to “puff” the dust through the access hole which ideally should be located above the nest. If I were treating the column, I would drill the hole as close to the top of the column as possible and treat through this point.
In theory, it should only take the one access point to get enough dust into the space to solve the problem as long as the nest is in fact located inside the column. From this location the dust should flow down and coat all areas of the void. I’d use enough of the dust to insure good coverage and I would do at least two treatments to make sure it’s uniform and complete. It will probably take 2-4 oz of Pyganic to get it properly dusted. I would expect quick results with most of the bees dying in the first day. By the second day there should be little activity and by the third day, if you still see them coming and going be sure to treat again but this time make holes closer to their access point thus making the dusting more directed at them. On a related note, if you see they have “drilled” access holes, treat them by dusting the holes directly as well as treating the entire void as described above.
Since this area is essentially an open air space, the use of a dust would be much preferred over any type of spray.
