Tea tree oil works great to get rid if all fungal growths.I have encouraged DH & the other neighbors to not engage him & to video if he tries to approach. As for my family ... He doesn’t get to talk to us without the sheriff present. The kids know to come in the house if they see him trespassing & to not hesitate to call 911. Just such a total suck. I was physically ill for over a month last year till he finally built that giant fence & disappeared behind it. But now he’s back... like a bad fungus.
Also smells like the Dickens, so maybe it will also get rid of your fungal problem.
Skunk raising though..... that would be easier probably, seeing as their stench just keeps on a coming!
