As a general rule, we suggest multiple releases to offer the best chance of achieving a satisfactory outcome. Releases should start early at the first hint of pest pressure. This approach is quite unlike that for pesticides which are often applied after a significant problem has already developed. The problem with this is that pesticides rarely kill all the pest species and often harm beneficials so that secondary flare is a common occurrence.

All the biocontrol agents that you order must be released as soon as possible after you receive them. Follow the instructions carefully. A follow up release – be it 2, 3 or 6 weeks later must be from a fresh order. It is simply not possible to keep beneficial insects and mites from one order for the application of multiple releases.
