In a December 2nd release, the Environmental Protection Agency announced a hold for a proposed ban on aerial application of synthetic pyrethrin insecticides, used extensively to control flies in layer houses.  Following submission of comments by the UEP and scientists, the EPA announced the delay in implementing a ban with continued use of pyrethrins allowed through 2024.

The delay will enable EPA scientists to gather data that can be use to address the issue of either a complete or partial ban with specific label restrictions.
