If you're worried about ticks, put up an owl box.

The animal driving most Lyme disease in the eastern US is the white-footed mouse. Ticks that feed on them are far more likely to come away infected than ticks that feed on other animals. The bigger the local mouse population, the worse the next year's tick year.

A single barred owl pair raising chicks can take hundreds of rodents in a breeding season. Owls also don't carry Lyme. The bacterium can't survive their digestive tract, so an owl that eats an infected mouse is a dead end for the disease.

Researchers at the Cary Institute, the leading lab on Lyme ecology, have been explicit about this: "Landscapes that support predators have reduced Lyme disease risk."

One owl box on its own isn't going to fix a tick year. But a yard with owls, foxes, bobcats, and weasels in it has fewer mice, and a yard with fewer mice has fewer infected ticks.

If you have woods or fields nearby, a properly sized barn owl or screech owl box (different species, different ...
