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).
Deer flies are water breeders and can travel long distances, making them impossible to control in their larval stages. However, there are a few ways to help keep them away from you. BugPellent Gel is a good repellent if they are bothering you while out riding. If they bother you more in a specific spot, such as near a pool or in a back yard, etc., then a trap may be another way to go. There are traps that you can build yourself. You can search online for plans to build the home made version by searching for Manitoba Trap. For deer flies, another trap that works pretty well is to get something like a kickball and paint it blue (deer flies are particularly attracted to blue), then cover the ball in a product called Tanglefoot (you can usually find this at places like HomeDepot), then hang the sticky blue ball in a tree near where you spend time.

It is a common and widespread belief that horses, being a flighty prey species, automatically fear predatory species. It seems logical to believe this.
The horse is a prey species. It is a grazing creature that, in the wild, always lives in herds on grasslands. It evolved millions of years ago surrounded by hungry predators mainly of the dog and cat family. This included wolves, lions and saber-toothed tigers.
Unlike many grassland prey species, such as wild cattle, sheep, goats, rhinoceros, and elephants, the horse is equipped with neither horns nor tusks. Its primary defense is flight. The horse’s anatomy and its physiology are designed to sprint from perceived danger.
What precipitates flight is the perception of predation, not the presence of a predator.
I became aware of this for the first time in 1949 when the Ringling Brothers Barnum and Bailey Circus came to Tucson. I was amazed to see a full-grown Bengal Tiger riding on the back of a horse. “How is such a thing possible?” I thought. “Doesn’t the horse, a prey animal, automatically fear a tiger, a predator?”
I had seen wild horses that had never had human contact panic when a man first approached them in a pen. That seemed “normal”. In time I observed that when such horses were approached by children, or most women, they were less inclined to panic. Why?
Similarly, when such horses were approached by a friendly, casual ranch dog, it did not result in blind flight. Weren’t dogs predators?
Predation usually take two forms:
I have been twice on veterinary safaris to East Africa. There one will see lounging prides of lions, a short distance from grazing herds of zebra, a close relative of the horse.
As long as the lions are resting quietly, the zebra, always aware of the lion’s presence, do not flee.
But, if a lion arises and stretches, the zebra focuses on it. If the lion then casually moves away from the zebra, they go back to grazing.
If, however, the lion crouches, becomes motionless and stares at the zebra, they immediately prepare to flee.
I noted, long ago, that when stallions want to propel their range herd of mares and youngsters into flight, they assume a predatory stance. They lower their heads, crouch, and fix their eyes upon their “quarry”. This motivates the herd into flight away from the predatory behavior even though that behavior is being displayed by a fellow prey animal – a horse.
Thus I learned that horses do not fear predators. They fear predatory behavior, the stalk and the charge. So anything unfamiliar to the horse that is stationary is alarming. It might be just a trash can, or a discarded box, or a rock that somebody painted their initials on, or a resting animal that it has never seen before like a pig or a llama – anything! This is why horses may shy at an unidentified stationary object. It isn’t stupidity. It is nature’s wisdom. In its natural environment in the wild, this is how horses manage to survive.
Similarly, anything unfamiliar, unidentified that moves towards the horse, may be identified as predatory behavior, and for the horse, the best way to escape a predator is by flight.
If we respond to such behavior by inflicting pain, as with the whip or spur or violent reining, we establish permanent fear of whatever caused the “spooking”. So if a horse shys at a sheet of paper on the trail, it is thinking “I see an unfamiliar stationary thing. I had better run away from it or it may hurt me”, and then if we hurt the horse, we have confirmed its fear. And, horses don’t forget. Horses with poor memories did not survive over the millions of years.
If an unfamiliar object comes towards the horse, say a kid on a bicycle for the first time, or a hiker with a big backpack, or a golf cart, or a tumbleweed, the horse’s natural reaction is flight. It’s not stupidity. It is nature’s wisdom. It’s the key, for a horse, to survival in the wild.
Horses can be desensitized, with amazing speed to any sensory stimulus, no matter how severe, providing that it causes no pain. Thus horses can become oblivious to the loudest noise, the strongest smell, the sight of anything no matter how vivid, and the touch of plastic sheets or electric clippers, or ropes on its body, and even a tiger riding on its back.
That’s why horses were so vitally useful to mankind for so many millennia in warfare.
Once we accept the concept that horses do not automatically fear predators but they do fear predatory behavior unless they are methodically and properly desensitized to it, we can understand how to best get along with and communicate with horses.
We will discuss such methods of desensitization in a future article.
Since horses have infallible memories it should now be obvious how important the first experience of any kind will be to a horse, regardless of its age. The first experience with people, dogs, cattle, curry combs, electric clippers, wheelbarrows, flags, halters, bridles, saddles, foot trimmings, fly spray, motorcycles, crossing a puddle of water, whatever, will be remembered forever. If that memory results in what we regard as an unsatisfactory response, it can be changed. However that requires skill, experience, patience, persistence, and empathy. Anger, impatience, and violence will worsen the problem.
Now you can see why determined, aggressive rapid movements and a fixed gaze on a completely green horse causes the horse to regard us as a predator, whereas a casual relaxed, soft approach, halting and even retreating if the horses reacts in a frightened manner is the best way to initially introduce a horse to anything new. Retreat is non-predatory.
Later, after the horse accepts the new experience with the indifference, then you can gradually increase the intensity of the experience. As long as it doesn’t cause pain the horse can accept it.
Horse training consists simply, of giving horses a choice between comfort and discomfort. The discomfort can be mental or physical and it can be quite mild. It does not have to be severe. The ultimate goal should be 100% respect and response, but zero fear. It can be done.
Ever since I became a regular user of Spalding Labs’ Fly Predators, over 40 years ago, I have recommended them for fly control to my clients, my neighbors and my seminar audiences.
Invariably, those who heed my advice are satisfied with the results. However, occasionally, the response is unusual and sometimes funny.
For example, one of my clients had a serious fly problem. Like me, she lived in a canyon where the summer temperatures often rise to over 100 degrees Fahrenheit, a paradise for barn and house flies. So, I recommended Fly Predators.
Sometime later she telephoned me and said, “I just received my first shipment of Fly Predators. I can’t see them because they are buried in the shavings in the plastic container, but that’s not why I’m calling. I see dozens of little bugs in with them. I’m afraid that they will damage the predators. Maybe they already have, because I don’t see the predators. Maybe the bugs have killed the predators.
I reassured her, “No! Those are the predators. They are hatching, so it’s time to put them out on the manure piles on your place.”
“But,” she protested, “If those are the predators, how can they kill the flies? They are too small.”
“Oh,” I responded, “They are very efficient at killing flies. Nature is full of small organisms killing large organisms.”
“Really?” she exclaimed.
“Sure,” I said. “The smallpox virus is so small that it cannot be seen under an ordinary microscope, yet that virus has killed hundreds of millions of human beings throughout history. And, I have seen horses killed by rattlesnakes less than three feet in length. That’s just two examples of smaller organisms killing much larger ones.”
“You mean the Fly Predators are dangerous?”
“Yes,” I replied. “But not to us. Only to the flies.”
