I guess the best place to check would be the guy’s site. Looking at his FB and related posts, it seems he’s limiting himself to fire ants and carpenter ants… both ants most people would call an exterminator for.
Would you be that angry about the exterminator? That’s how I had the carpenter ants in my house killed. No art, just had a guy come out and poison them. Same with the termites. Is it the act of doing something creative that really sets you off? I’d say it costs more than extermination, but frankly that depends. The termites set me back well over 1k.
