Price includes delivery via Priority Mail (US Postal Service) either to your mailbox, or to a Post Office box. Insects are sent out Monday through Wednesday. Place your order at least 3 business days in advance of desired shipping date. 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.
Muscidifurax raptorellus, Muscidifurax zaraptor, and Spalangia cameroni are tiny wasps that don’t bother humans, but parasitize the pupae of many species of flies found in areas with livestock, breaking the life cycle of the flies.
You cannot place too many parasites. You can place too few. For dairies, feed lots and horse stables, we recommend between 300 and 500 parasites per animal per month during the fly season (March to October or November depending on weather). For confined hog operations, this number will be between 200 and 400 parasites per animal per month. Chickens require from 1 to 5 per bird per month. If your fly problem is very severe, these numbers should be increased; the first and second releases especially should be doubled or tripled.
Note: These creatures will 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. Be sure to open your box when you receive your order to prevent these beneficials from suffocating. 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 the Post Office 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.
