We have (had?) some ticks in our backyard and I came across these which I thought was a clever attack angle: tick tubes.

Permethrin-soaked cotton balls in a tube, mice find them and build nests out of the freely available cotton, ticks that the mice have gathered while walking around die when they come back to the nest.

Some birds eat ticks including guinea fowl of all things.

If you are out in the woods and you come upon a roughly circular area of crushed down grass, that is a deer bed. Try and avoid walking through it, deer beds are full of ticks.

The deer trails are a lot harder to avoid.

Calls to mind one of my favorite Simpsons moments.

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.)

I got bitten by a mosquito in Ottawa a couple years ago that sent me to the hospital.. I stopped near the river while cycling to see a raccoon for few seconds, was more than enough for that lil sucker to do the job.

> Twenty 50-m trail segments across two sites were randomly assigned to intervention groups: untreated woodchip borders, deltamethrin-treated woodchip borders, and ten assigned to untreated controls.

> Treated woodchips reduced I. scapularis adult and nymph density by 99 % (incidence rate ratio (IRR) = 0.01, 95 % CI: 0.001–0.08) relative to controls, while untreated woodchips achieved a 48 % reduction (IRR = 0.52, 95 % CI: 0.34–0.78).

Another worrying proxy for how deeply climate change is bleeding into everyday life: coffee prices, orange juice prices, and now having to engineer huge trail areas with woodchips just so people can avoid being bitten by exploding tick populations.
