Biological products are generally temperature sensitive.
Most of them require warm temperatures to be active.
If the temperatures are too cold or hot they can also die.

Avoid using chemicals for pest control while using these products.
Also allow a gap from starting your biological control
programmes and the last time chemicals were used.
