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.
Extended Deer Fly Information
"We and they love your Fly Predators. No annoying flies around the manure in the barn or even in our house." says happy Fly Predator customer Kathy S.
Kathy cares for her big and beautiful oxen Dale, Max, Jake, and Chip by using Fly Predators. Her oxen weight about 2,600 pounds each and stand anywhere from 6 feet to 6 feet 2 inches tall! That's a lot to love! :-)

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.”
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.
