About - There are over 100,000 species of caterpillars so nearly all of us will at one time or another encounter this pest. Caterpillars are the larvae of moths and butterflies. They do not reproduce exceptionally quickly like other pests, however, they are ravenous eaters and can be the source of total crop loss through complete defoliation.
Monitoring - Caterpillars are not usually hard to spot many larvae are large enough to see with the naked eye. Also look for missing leaves or ones with holes. Caterpillar excrement can also sometimes be spotted.
Treatment - Nematode Steinernema carpocapsae is a parasitic roundworm that finds a larvae host, crawls inside though natural openings and infects the host with bacteria - killing it from the inside out. These microscopic worms are a good choice for naturally dealing with caterpillars.
