Educational Insecticide


It’s starting to get cold here in Colorado. We will start to experience all of the lovely changes of fall into winter, the trees changing colors and losing their leaves. Also, some not so lovely changes. As we all begin to get cozy indoors, there are others also looking to get cozy with us… spiders. However, spiders aren’t looking to get inside our house because they are cold, interestingly enough, spiders do not get cold. Spiders produce an anti-freeze type chemical called polyhydroxy alcohol. It works similarly to the antifreeze we put in our cars, allowing spiders to survive temperatures as low as -5°F. The reason they come inside is to follow their prey (other insects that do get cold and migrate to warmer spaces).

Spiders seen in Colorado are not bound by the territorial lines decided on by humans, this makes it difficult to accurately record just how many species are living here. We can however confirm the common species as seen below.

Spiders in Colorado

I don’t know about you but I think I’d rather have some less scary guests visiting my home this winter.

“So far this year, the state can expect an increase in the Western black widow because of a humid and wet summer. He said the bugs they prey on have increased, which helped their population thrive.”

-Francisco Garcia, entomology manager at Butterfly Pavilion.

It’s important to stay on high alert this season and keep our homes spider free. Luckily, your friends here at Autumn tree are here to help. Our Bug Barrier program is the best way to keep insects and spiders out. We offer five applications spaced throughout the year.

Talstar Spider and Insect chemical

We use a powerful chemical called Talstar that eliminates a wide variety of insects. Our lawn care specialists use applicators to spray the Talstar around the foundation of a home. We can also spray other structures on a property such as sheds and detached garages.
