I have only got one in the Kitchen hun - a bird free zone. Great in as much as getting loads of tiny flies that get stuck easily. Yes I'd always prefer to let them out than kill!I last used these a decade ago when @JessCheekyMia cockatiel Cheeky flew into it and got all stuck to it. Luckily a good shower was enough to remove the fly paper. After that, fly paper was banned from our home.
During the summer months, we have windows and doors open for ventilation, our windows and doors have net curtains fitted, not just across the top, but I've put my sewing skills into action and these are also fitted down the side and bottom using a hem and curtain wire, hooks and eyes. Our doors are only fitted from top (two wires that runs along at the top one for each curtain) and sides, each door have two curtains that over lap down the middle to allow me to walk through them. I've also have a bead curtains as well as the nets for our outside doors. Our windows also have a window restrictiors fitted. All our internal doors have net curtains also fitted. We seem to keep most of the flies out and all our birds in. Any flies that do enter our house, I catch using a glass jam jar over them and releasing them back into the wild. As much as we see them as pests, they are actually good for the environment
We know they’re frustrating but before you pull out the fly swatter, spare a thought for the many awesome things flies bring to the ecosystem.blog.csiro.au
