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).

When I was young, starting previously unhandled colts on summer jobs for cattle ranches in several states, the term “colt” usually referred to 4 or 5 year old horses. Occasionally, one was older, maybe 6 or 7, or, rarely a 3 year old.
The exception was at the racetrack. Racehorses and only racehorses were started as 2 year olds. The term “futurity” was limited to racehorses.
Today horses are usually started under saddle as 2 year olds, in all breeds and all disciplines, and I see an increasing tendency to ride them even younger, at 22 months of age for example.
There is a popular misconception that, if the growth plates (the epiphyses) of the leg bones are closed, as revealed in radiography, that the colt is “mature”.
That simply is untrue. It just means that the end of the bone, which has been x-rayed is no longer growing, but other bones plus soft tissue structures such as tendons, ligaments and muscle may still be quite immature.
In my long career as an equine veterinary practitioner, I found that the most frequent cause of lameness in horses was damage done by excessive work at too young an age. And, this is increasingly true. How many times, examining a qualified performance horse, which moves soundly at 5 to 7 years of age, have I found that when I flexed a limb, the horse winced with pain. Subsequent radiographs revealed the very early signs of joint deterioration.
A very generous client who had become a good friend once offered me and my wife a free reining horse, a mare who had competed successfully until the age of 5. Then she had been bred and I was told that we could have her as a gift, as soon as her foal was weaned.
She moved soundly, but, when I flexed her right fetlock, she said, “Ouch!” And, after sustained flexion, she walked out lame. I turned her down and, two years later, I was asked to examine her for chronic right fore lameness.
Horsemanship, in our society, has greatly improved in most ways during the last four decades with one exception. We are starting colts younger, working them harder (one reason being that we have selectively bred for better performance; faster, more agility, and all of this damages the immature body.)
Selling younger horses is profitable for the breeder, training younger horses is profitable for the trainer and easier than waiting for full maturity, but it is a disaster for too many of these young horses.
The epidemic of young horses becoming unsound is also a disaster for the owner, who too often defers to what the breeders and trainers recommend. Only the veterinarian and the pharmaceutical industry profit by this increasing phenomenon. Too much stress at too young an age.
You may hear deceptive results from “scientific studies,” that exercise is “good for growing colts”.
Of course! Exercise is good for all horses. But reining, cutting, jumping, etc. an immature horse is damaging.
I never started one of my own colts under three. Most were 6 to 12 months older. And, I never overworked them. At 5 I would turn them over to a selected trainer to begin their discipline training.
The one time I failed to do this was with the first mule I raised. Because I mistakenly believed that mules were “tougher” than horses, I broke her to ride at 2 and turned her over to one of my clients to be trained as a hunter-jumper.
She had a very successful career, winning English and Western shows, often beating horses, going on pack trips and round ups, and even cutting cattle without a bridle.
Great! Right? But she went lame in middle age, prematurely, because of too much, too soon.
I have a library of books written by famous horsemen. A while ago I went through every book looking for the colt starting ages they recommend.
Why does the Spanish Riding School recommend starting their Lipizzaners at age 5 and not subjecting them to really hard work until age 7? Here’s why: The horses evolved on the Plains of North America. They survived successfully despite the constant presence of carnivorous predators, mostly of the cat and dog family. This included huge species like the cave lion and the primitive wolf.
They survived because of an effective defense. They were fast, agile, bonded in herds, and had very, very perceptive senses to detect possible predators and respond with high-speed flight. They could outrun most big cats and canines.
Also they are a precocial species, able to run, follow mom, and escape and learn, soon after birth.
So, obviously, exercise is beneficial for the young horse. Indeed, it is essential for normal development.
However, “exercise” does not mean excessive sprinting, longeing, or twisting and turning or sliding stops. It means walking, trotting here and there, and running and playing once in a while.
Excessive exercise, which unnaturally stresses the young body is damaging: a common problem seen in human athletes, talented but not yet mature enough for competition they can survive when older.
So, if you love horses, if you care about them, if you want them to still be sound and working at 20 or 25 years of age, wait. You can do so much valuable training on the ground. Don’t rush them.
I am presently, as I write this, 90 years of age, and I treasure Scooter, whom I started at 4 years of age. She is now going on 30! (Together we are almost 120 years old.) I am so glad I waited. So glad I periodically worked her on the ground, producing such a calm, reliable, trustworthy, patient, capable old mount. I love riding her and hope we have more time together.
Incidentally, I was a gymnast at 16, a pole vaulter at 17, a rodeo contestant at 20 and have endless orthopedic problems. That’s one reason I still ride. It hurts to walk.
I opened my practice in rural California in 1958, hoping to establish a group practice. By the end of the first decade I had two practice partners, Dr. Bob Kind and Dr. Larry Dresher, both Kansas State University graduates.
It was July, and I was on a call to Bell Canyon Stables, a large and impressive facility at the Northeastern corner of our practice territory.
I was examining the left hind foot of a mare. It was noon and the temperature was 105 degrees, Fahrenheit, when I suddenly realized that there were no flies around, annoying my patient or me.
It was so unusual during the summer heat that I decided to ask the stable manager, a young woman named Jennifer, what kind of chemical spray they were using to obtain such impressive results.
I will never forget her answer:
“No spray! No chemicals! We have been using Spalding Fly Predators since last summer and we are getting fantastic results. There are only a couple of homes in this canyon and we have the only animals here at our stable, so we are getting excellent results with the Fly Predators.”
When I returned to our veterinary hospital at the end of the day, Dr. Dresher came in shortly after I did and I told him what I had learned. I had seen ads for Spalding’s Fly Predators, but because we vets are deluged with advertising, I had not been convinced of their efficacy.
My practice partner said, “Bob, I live in the Santa Rosa Valley, surrounded by small horse properties. I’ve been using Fly Predators since last year, and I see a noticeable reduction in our fly problem.”
The next day I placed my first order for Fly Predators. That was half a century ago, and I am still using them. I also convinced my neighbors, who had horses, cattle, goats, emus and, of course, dogs, to become Fly Predator customers.
We still use insect repellents on our horses, because the results, although very significant, are not 100 percent.
Before I bought my little horse farm in 1978, I remember it because the owner was a client with a couple of horses. When I got a call from him during the summer, I remember having to spray myself with insect repellent, the fly population was so severe. His horses were covered with thousands of flies, to the point where fighting them was of no avail. They just stood there, heads down, no tail switching, no foot stomping, just surrendered to the bugs.
I hope this explains my allegiance to Spalding Labs, and why I advocate their products.
