In countryside (rural) tourism, especially when it is single or few houses somewhere in the middle of nowhere (woods), instead of having a water system including proper bathroom one sometimes gets a well for water and a hole in the ground for a toilet.
During summer it becomes a huge attraction to all sorts of insects, especially flies. It can get so bad sometimes that it makes it hard to use the toilet, with tens of flies trying to fly into your nose, mouth, and eyes.
I am of the opinion that while in nature one should have as little of a footprint as possible, but bathroom being at the base of Maslow's pyramid demands some sort of solution nevertheless...
I have already tried:
- bowl of vinegar
- the 'proper' wasp, and fly drowning fluid
- sticky tape
None of which really do much, as the number of flies always beats whatever I throw at them.
Is there a good way to "get rid"(or make them go away) of flies in the outdoor toilets? I would prefer a non-lethal solution, but likely there not being an efficient one, I would appreciate a brutal one too, if there is such, as I honestly one time thought of making a fly flamethrower...
