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.

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.

Flea free, finally!

We have a dog and 2 cats in Texas where the fleas are resistant to almost every treatment the veterinarian has to offer. We've been desperate to find some relief from their endless suffering. These were the answer we were seeking! Flea season arrived a couple of months ago, but not in our yard! The millions of fleas we faced every summer are gone, and our pets' suffering has come to an end.

2 Weeks-Fleas Almost Gone!

This may not seem impressive to some, but my flea issue comes from multiple rescue cats in an indoor/outdoor enclosure in the South where nothing ever dies! Even in high grass, these nematodes have been LIFE-SAVERS.
