Shoe spray reminder!

This Monday (June 1) and Thursday (June 4), we are treating shoes with permethrin for FREE.

Treated clothing and shoes will protect you for up to 6 weeks or 6 washings. That means if you treat your shoes now, they will be protective until mid-July!

Just come from 9-12 noon with an extra pair of shoes and we'll spray them for you with permethrin, a compound proven to protect against ticks.

This week I was out collecting ticks as part of my surveillance work. You can see in the vial that there were several nymphs. I wasn't worried about being bit. And I didn't have a single tick on my body.

(The grass is in there to keep them from drying out. They die quite easily without the right level of humidity.)

New upcoming programs for June.

Tick and mosquito programs are still happening. We have a few programs on fireflies. Stay tuned, there could be more. Plus several nature walks happening.

Feel free to reach out with any questions or comments. Some of these events require registration beforehand.

Also, these are just the public programs. You can always book your own private programs through our organization as well.

Eastern tent caterpillars (Malacosoma americanum) are active in the area.

If you are seeing webs around trees in the area, it is probably this species - especially, if the webbing is on black cherry (Prunus serotina).

Eastern tent caterpillars are commonly misidentified as spongy moth (Lymantria dispar dispar, formerly called gypsy moth). They can be easily separated from spongy moth, because spongy moth does not form webs at the crotch of trees.

While the defoliation and webs may appear concerning, these caterpillars are not invasive species. They are native to our ecosystems and the native plants in our area have evolved to withstand losses at a population level.

Eastern tent caterpillars can occasionally have outbreak years where they can impact many plants in the area. It's too early to tell if 2026 will be one of those years.

Often, management is not required. They rarely cause mortality. But, care can be taken to preserve individual plants of high ornamental or sentimental value.
