I didn't know if this topic is supposed to go specifically here, but I figured others could give me some advice on the topic. My neighborhood (Northeast FL) seems to have an abundance of Pygmy Rattlesnakes, Coral Snakes and Water Moccasins. Recently a neighbor's dog was bitten by a Pygmy Rattlesnake and others have found Coral Snakes and Water Moccasins and they are being spotted more frequently. I think its because of all the baby toads, frogs and anoles. Is there something to spray/put down along the edge of your property to deter them or will they just keep coming? Lastly, there is an armadillo who likes to keep coming around at night to dig up everyone's lawns. Apparently, its said to be the size of a small pig and has broken a trap. Is there are deterrent for it as well?
I don't actually know how effective it is, but I've heard armadillos hate the smell of garlic. Maybe try that? Make sure there's no food out either.
I would tend to argue that you *shouldn't* be taking steps to deter or eradicate them - their presence is a good sign that your area has a flourishing ecosystem.
Armadillos can cause structural damage to homes through tunneling and they can tear up gardens as well. Repelling them is understandable.
Well, firstly you'll note my quote was referring specifically to the reptiles and secondly, to paraphrase your own words, humans cause ecological and habitat damage and therefore the armadillos trying to repel *us* and undo all we have wrought is understandable!
Sounds like a beautiful, biodiverse area. The most a 9 banded armadillo has ever been recorded at is 14 lbs. So there are pigs that size, but they're baby pigs. Most are half that.
Look at this manual: Chapters | Prevention and Control of Wildlife Damage I have no idea how well it works, but looks professional. But I was amazed reading chapters how to deter e.g. pumas or polar bears.
