Original Question: Fly Predators and rain by Jessica S.

It rained after I put my Fly Predators out, will this kill them?

Suggested Answer: RE: Fly Predators and rain by Jessica S.

Some rain is generally not a problem for Fly Predators, especially if they have been released in sheltered areas.  However, if you have a sudden storm with a lot of run off and/or flash flooding within 48hrs of releasing your Fly Predators it could potentially wash them away and you should consider replacing the shipment.  If it’s been more than 48hrs since you’ve released your Fly Predators, then most will have had time to emerge and move into safer areas.
