Lacewing larvae are small visible insects that are predators for thrips, mealybugs, spider mites, scale, cabbage worms, hornworms, and aphids. The life cycle of a lacewing larvae for indoor houseplants is about 10-14 days. It is very rare for lacewing larvae to reach the adult stage. They are excellent for active infestations, though you can use them preventatively as well.
Bottle: One bottle contains approximately 1,000 lacewing larvae and eggs in a buckwheat husk substrate, however lacewing larvae are known to cannibalize each other so the actual number may be less. One bottle can treat about 15-20 small/medium plants depending on the amount applied for each plant and proximity of plants to each other. It is not recommended to release lacewing larvae with the buckwheat husks directly onto non-soil substrates (LECA, pon, perlite, moss, water, etc.).
Hex Cell: One hex cell contains 400 lacewing larvae that are individually separated by small cardboard cells so as to reduce cannibalism. One hex cell can treat about 30-50+ small/medium plants depending on the amount applied for each plant and proximity of plants to each other. The hex cell is ideal for plants in all substrates.
