Through a combination of two of my hobbies, I learned that pyrethroids are toxic to aquatic animals. Glad to see that they used "locations [that] were situated away from waterbodies". Pyrethroids are very powerful tools for insect control (and non-toxic to humans) but any place where you have runoff or ground seepage is going to be a problem. Aren't those places the ones most likely for ticks to thrive -- areas near bodies of water where animals like deer come to drink?

So hot take: this would only be useful in places where there are not a lot of ticks?

(PS: Permethrin-sprayed clothing is very effective.)

They’re also very toxic to cats, which is why dogs & cats have different flea & tick medicines.

Also bad news if your dog is prone to seizures, as mine was.

Deer ticks will go after pretty much anything warm blooded: coyotes, mice, dogs, etc etc etc.

Proximity to water doesn't seem to factor much either. Where I live, ticks this year are horrendous and everywhere.

This reminds me I need to respray my tick pants. Thanks.
