Beneficial insects have proven to be an effective alternative to pesticides in the greenhouse. For at least one month before you add beneficial insects it is important not to use residual pesticides, such as malathion and kelthane. Use up to one week before releasing your beneficial bugs.
Beneficial bugs work best when given an early start.
If you don't notice pests until they are well out of hand, spray with one of the foregoing sprays to get them down to a manageable level first. Then release your beneficials and they will keep the pests under control. All our beneficial insects are shipped with detailed instructions.
