Samples for insect and plant identification may be brought to any library branch. Staff send the sample and the completed plant and insect diagnostic form in an envelope addressed to Fairfax County Cooperative Extension. Residents receive a response directly. No fee is charged. Insects must be dead, and it is best to send more than one. They should be enclosed in an unbreakable vial or jar. Plant samples must not be completely dead, and should contain as much of the plant as possible. Both healthy and sick plant tissue (especially the area where the two intersect) are needed for analysis. Samples must be sealed in crush proof containers.
