Re: Spraying for Army Worms
Likely will be a pyrethroid. Will kill any bee it contacts immediately. As long as it doesn't drift into your hive you should be fine. Field bees are susceptible, but if they aren't working that field then the only ones at risk are the ones traveling thru during application till it dries an hr or 2 later. Mind the wind during application. If it's gonna blow toward your hive in the least bit, I'd consider moving the hive if possible.
Any chance you get along with him well enough he'd skip a 50-60' wide swath from your hive? That'd help immensely.
I have no experience closing hives up for a day in the summer, but bad things can happen with that.

After the fact, I always know what didn't work.
