Formic acid use #874060

Asked June 21, 2024, 11:50 AM EDT

Hello, I was wanting to use Formic pro on my hives soon. I believe I’ve heard you guys say that the temperature restrictions are mostly for the first few days of treatment and just wanted to confirm before I applied them.

Thanks for reaching out with this question.

Here is information from NOD, the manufacturer of Formic Pro: https://nodglobal.com/formic-pro-application/.

Here is Formic Pro's USA label: https://nodglobal.com/wp-content/uploads/2023/08/Formic-Pro-US-Label-Set.pdf. The label states, "Outside daytime highs should be
between 50 - 85°F on day of application. Hot temperatures (≥92°F during the first 3 days) may lead to excessive bee, brood and queen loss."

I normally use Formic Pro when the forecast for the at least the first few days of application is between 50 - 85°F.

Happy beekeeping!
