Thank you for explaining this so well.

Depends what you are trying to control. First....read the label see what the active ingredient is, the label will also have the target insects listed. The OP would use BTi to control mosquitoes....

Apistan is a synthetic pyrethroid, and beeks put it inside the hive. Does it kill all the bees?

Not much light in there, and like many labels there is bee language "ENVIRONMENTAL HAZARDS

If your crop is not flowering then there is no issue with choice of product.

If your crop is flowering you can use a BT product for caterpillars or an insecticidal soap for aphids and whiteflies....

Always lots of drama and fear mongering when an aerial mosquito adulticide happens. Like the 6 million acres that got done in Texas recently. Notice how in this thread no one reports back with a...

So now over 3.7 million acres sprayed in Texas, now happening in Florida as it does after every hurricane or disease outbreak.

Last post was 3 days ago it has been some time since the spray and...

It is only used for adult mosquitoes.

Mosquito adults ULV sprays use the same 2 classes of insecticides outside the hives that bee keepers use to treat for mites inside the hives. Around here beeks are used to mosquito control and like...

Thanks for the feedback.

Hives pop up everywhere as the migratory keepers come here to get brazilian pepper, mangrove, and orange...

I would but "bugs" is not enough information.

Just like a Doctor you have to know what the specific microbe is before you choose the specific treatment the is effective in killing it. That is the...

Destructive Bee Disease Detected at Hive in Kula, Maui

Darn those spores.

Very difficult to answer when you are only providing "pesticide/insecticide", all pesticides whether organic or synthetic must be evaluated individually. The spectrum of non-target effects varies...

This kill was all over the media.

The results of the Clemson investigation below is much harder to find.
No shock value = not newsworthy. Got her more than $7k from the gofundme folks though, I...

Very informative, I learned much, thanks.

Agree, that would cover the local beeks, no way to keep track of the migratory hives, which are the majority in my area.

More important, assume you are notified, now what?

Looks like notification to me. A more important question is what would you do after notification. I imagine few have contingency plans to move bees on short notice.

My $.02 is to keep the hives >300ft from the road, since this is the effective swath to kill a small bodied mosquito. Typically sprays are in the evening when bees are home, and this way you don't...

BT not a problem, affects only worms that ingest it while eating the plant.

Sounds alot like I'm not a doctor but I slept at a Holiday Inn last night.
