Are you wondering why your Fly Predators haven't hatched yet and want to know how to help them hatch quicker? Jess our Fly Predator Scientist has the answers...
Why Fly Predator Hatch Times Vary
The species that comprise Fly Predators have a life cycle that is very dependent on overall average temperatures. At ideal conditions (around 85°F) it takes a minimum of 2 weeks for the Fly Predator to develop from egg to adult. At much cooler temperatures, they can take 6 weeks or more to hatch.
Generally, we try to send out Fly Predators that have already been incubated for about a week, so that in the warm summer months, they will begin hatching within 5 days of arrival. However, temperatures during travel and temperatures where they are being kept can have large impacts on how quickly Fly Predators hatch. During the first shipment of the season, it’s not unusual for your Fly Predators to take 10 to 14 days after arrival to emerge. It’s much faster than that during the heat of August.
How Do I Help My Fly Predators Hatch Quicker?
If your weather is warm and you want to make sure your Fly Predators hatch as quickly as possible, keep them at a consistently warm temperature once you receive them. Don’t put them in direct sun as this can make them too hot while in the bag. On top of a refrigerator is a cozy place, but write a note so you don’t forget them.
If your weather is cooler than normal, particularly if you have a chance of freezing night time temperatures, you will want to slow down the hatching of your Fly Predators. If they traveled through cool temperatures on their way to you (which often happens in the early spring and late fall), even once kept consistently warm, it may take 2 weeks or more for your Fly Predators to hatch. If kept outside once they arrive, and night time temperatures are still falling down into the 50’s, this could also result in delayed hatching, even if daytime temperatures are getting into the 70’s or higher. You can match the speed of emergence to match your weather, which is also how quickly your pest flies will be emerging.
Bottom line: don’t worry if your Fly Predators don’t hatch right away in the spring and fall. Try to keep them in a consistently warm location, such as on top of a refrigerator or other electrical appliance that generates a little heat (just don’t cook them).

Fred Stone, the world’s foremost painter of horses, has been a client, neighbor and friend for half a century.
Fred’s paintings, mostly, but not exclusively, are of Thoroughbred racehorses. Living in a modest rural home as long as I have known him, he paints in a tiny studio, producing works of art treasured by horse lovers everywhere. His art even decorates large structures at racetracks here and abroad.
What I find most impressive about his work is how he captures the precise personality of the horses. I can look at the expression in the head and the eye of the subject, as I can on a living horse, and see in the painting the exact mood and attitude of the horse.
And, amazingly, he does this in watercolor!
Fred graced our practice with some of his treasured prints, and we also have several in our home.
Fred’s book, Reflections On A Golden Age, subtitled The Racing Art of Fred Stone (Equinart, Inc. 2010) is a coffee table masterpiece, filled with the author’s great artwork plus text by him and guest writers.
Horse lovers, and especially those who treasure horse art will adore this book.
I am a compulsive reader. Always have been. I keep a book in each bathroom, next to my bed, on the dinner table, in my car, several where I watch TV (I read during commercials), and I even carry my own books or periodical journals to my doctor’s appointments and even to fast-food lunch facilities.
So sometimes it takes many months to get through a book.
My colleague, Dr. Marcia Thibeault, sent me a copy of her book, I Make Horse Calls. I reviewed it and thanked her for it. I love reading other veterinarian’s books. James Herriot really started something!
Then, months ago, she sent me the sequel, More Horse Calls. I fast-read it and then, afterwards put it in one of our bathrooms for more casual, in-depth absorption.
Halfway through it last night, I was surprised to find myself in it.
Thank you Dr. Thibeault. Apparently you see that my imprint training method, used on newborn foals helps to produce a gentle and cooperative patient after they are mature.
An excerpt from More Horse Calls.
Luckily Sunny had been imprint trained, a process made popular by veterinarian Dr. Robert M. Miller. Imprint training takes advantage of a foal’s ability to learn rapidly right after birth. By exposing a newborn foal to potentially threatening stimuli, and showing the foal there is no real danger, the foal relaxes and a strong bond forms between horse and human. These imprint trained foals have less fear. If the foal is also taught to yield to pressure rather than fight against it, when it later becomes trapped, the foal soon finds struggling increases its pain, so it is more likely to stop struggling. They are also more willing to let humans help them. I hoped Pat’s early handling of Sunny was paying off now.
