Description
Each sachet contains 6000 pupae of the tiny parasitoid moth: Trichogramma evanescens, a UK native species. The wasps are truly minute, almost invisible to the naked eye.
The sachets have an exit hole on the front and back.
There is no need to open or cut the sachet.
It usually take 2-3 days for wasps to emerge and approximately 2,000 wasps will hatch each week. This delayed hatching increases the effectiveness of this treatment as new wasps will emerge to tackle moth eggs as these are being laid.
