Rainfall will have little effect on your beneficial insects. You should water as you normally would.

Koppert products should be applied as soon as possible after they arrive at your home.
Yes. Most products are very temperature sensitive and should not be exposed to thermal extremes. As a rule of thumb, if you receive a product and must wait a short time before applying it to your plants, you may store the package in your household refrigerator for 1 - 2 days.
To work properly, most products require warm temperatures in the growing area. As a rule of thumb, if the temperature is OK for the pest, it is OK for the beneficial insect. Guidelines for correct temperatures are included in each shipment.
No. Biological control takes time to work, but the results can be worth the wait. If used correctly, beneficial insects will provide effective pest insect control without the use of toxic chemicals.
It depends on the chemical that is used. To answer your specific questions, visit the Koppert worldwide website (www.koppert.com) and utilize the online

Yes. In many cases they can prove to be a valuable tool in the home garden. Read the recommendations for each product carefully to see where it can be used.
Generally, beneficial insects are either predators or parasitoids. Predators eat their prey while parasitoids use pest insects as a host for reproduction. In both situations, they can reduce pest populations to the point where they are not a danger to your plants.
Koppert biological controls are dependent on a population of natural enemies for their survival. In an ideal biological control system, there will always be a population of beneficial insects and pests in order to keep a natural balance. However, in most situations, the beneficial insects tend to disappear once the pest species has been eradicated.
Not at all. Koppert products can only have a negative effect on their natural enemies.
No. Beneficial insects are chosen for their ability to control pests and do not cause plant damage.
No. All of the Koppert beneficial insects are naturally occurring parts of our native ecosystems.
Koppert is the largest producer of beneficial insects in the world. We have insectaries in both Europe and the USA, plus co-operative production arrangements with many other producers of specialty beneficial insects.
