Ugh. HATE ticks! Virbac makes a good tick spray for yards. I don’t know if a growth regulator (IGR, like Archer) would work on them since they’re not insects.
Just googled & Methoprene is the growth regulator for ticks. Don’t know anything about it wrt to safety/ applications, though.
Guinea hens and chickens just LOVE ticks. And the HOA’s and towns hate the birds. So which is worse ticks and tick borne diseases or pretty birds that walk around and eat them.
On the negative side of course is the birds can be loud and noisy and the do shit. But when they are free range and not cooped up the shit is very well dispersed and is nearly unnoticeable.
Would DDT work on Ticks?
