Reddit mentions of AIRCROW Wasp Out Fake Hornet's Nest Decoy Wasp Deterrent

In general, I'm a "preventative" type guy. I don't like killing anything that could affect the ecosystem (which is basically everything). I know that sometimes it's not possible to just use preventative methods but here's my $0.2

Most hornets/wasps are very territorial, so sometimes putting up things like this will help. It's worked on a few client's homes. It doesn't even have to be as fancy as that. I've seen some people put up Chinese lanterns painted gray that have had success. Not sure about subterranean wasps/hornets though, they might be tricker.

Bees are generally good (pollinators) so if you have a big yard, you could "encourage" them to move to a part of the yard that you frequent less. Things like planting flowers that bees love can keep them occupied elsewhere. Or if the problem is serious, find a local beekeeper. I've worked with a few to move hives, so that way the bees keep pollinating, but there's less chance of incidents (though in general bees that can only sting once are pretty difficult to make angy enough to sting you)

Snakes I'm not too sure about, as I pretty rarely encounter them (and most of the snakes here are nonvenomous). Those sonic emitter things seem to basically do nothing, as my dad put them all around his garage and he's still found pine snakes lurking about (as well as their food sources). My best guess would be to try to reduce/remove potential food sources. So combating mice, chipmunk and rat populations would probably help. Things like sealing up garbage better, putting down traps, etc. Also, snakes are exothermic, so reducing the number of cool places they can go (like hidden places under rocks), and sunbathing areas (areas like rocks or completely unshaded patios) might help, but I'm guessing not to a very effective level.
