The description says that it a refill for a 50 gal system but the package says a 30 gal system. Can you verify?

Answer by Chewy • Mar 20, 2020

Great price

I use this every summer in my spray system and it gets more and more expensive. Chewy had the best price by far which I appreciate.

It works

With a good spray system, this keeps the flies and all other bugs and spiders out of the barn.

It works

This year was tough with the flies until we installed a system for the barn. The pyranha concentrate is the product we use to kill the flies. My horses LOVE it.

My horses love it! I’ve had this for 25 years, and would not have a barn without it.
