Once you have ordered, send me an email at firstname.lastname@example.org and let me know you have ordered and give me your name and address as well as the name and address of the organization where you want me to send 5% of your order at the end of the season. That way I can make sure your order gets posted to my account and the proper organization gets their donation! At the end of the year, I will send you an email letting you know how much money was donated!
I've been using Spalding for 5 years now and these tiny wasps, which don't bite or sting, have been doing a great job. Definitely, we have fewer flies than neighboring farms not using fly predators. Spalding also has a great brochure that describes different kinds of flies and gives other suggestions for reducing flies on your farm. This brochure is loaded with good information on how to identify and prevent flies. I will be glad to send you a brochure which includes an order form and 17 pages on great info on flies if you send my your address.
