The beneficial nematodes we sell are parasitic to insect pests that typically have a developing (larval or pupal) stage of life in the soil. They have been known to parasitize above ground stages of adults, nymphs and larvae. They will not harm mammals, aquatic life, birds, reptiles or amphibians. After being applied to the soil, the nematodes locate pests and enter through various body openings or directly through the body wall. Once inside, the nematodes produce bacteria that is injected into the pest's blood.
Beneficial Nematodes release the bacteria in order to create food and a hospitable environment for their own reproduction. As the food resources within the dead pest become scarce, the nematodes exit and immediately begin searching for a new host. As long as there is a suitable host, they will continue to survive and parasitize.
Steinernema carpocapsae nematodes are effective against mobile pests listed below.

Price DOES include delivery. Ships via FedEx 2 Day to a street address only (no Post Office box).
Insects are sent out Monday through Wednesday. Place your order at least 3 business days in advance of desired shipping date (Monday holidays will delay processing of order). Unless you specify otherwise, we will send your Beneficial Insects on the next possible shipping day. You could also request delayed delivery in the Order-Specific Comments box. We can only accept ship dates up to three weeks out.
These are shipped with cold packs in warm months. Do not be alarmed when the cold packs arrive warm or melted, as this will not affect the viability of the product. However, these creatures may die if left in direct sunlight or in a rural mailbox on a hot afternoon, or in cold weather. We only guarantee viability if someone accepts and inspects the insects immediately upon delivery. You must contact us immediately upon delivery if you suspect a viability problem.
Because of this, often the best address to use is a work address. If FedEx is instructed to leave the package in a cool, safe place and it’s for a short period of time, viability should not be compromised, but cannot be guaranteed. If no one is available and no instructions have been left, delivery may be re-attempted the next business day. However, viability may be compromised and will not be guaranteed.
