What Is Integrated Pest Management (IPM)?

Integrated Pest Management (IPM) is a science-backed strategy to reduce pest populations while protecting the health of your animals and the environment.

IPM stops pests at every stage of their lifecycle By combining biological, cultural, mechanical, and chemical controls.

How does IPM work?

Fly Predators® and your IPM Program

Biological control is the use of a beneficial organism to control a pest organism. Fly Predators are a unique blend of parasitoid species that work together to optimize biological control of filth flies. Biological control is a key component of any IPM program.

What to Do: We will send you the ideal quantity of Fly Predators for your unique situation. Spread them in areas where flies reproduce, and Fly Predators will kill the flies before they emerge!

Cultural Control

Cultural control includes any measures taken to disrupt the ideal living conditions of target pests.

What to Do: You can help reduce fly populations by incorporating good manure management, using bedding materials that reduce fly production, use drying agents in wet areas, etc.

Mechanical Control

Mechanical control includes any means of physically removing pests.

What to Do: You can use fly traps, fans, and vacuums to remove or deter adult flies in the environment.

Chemical Control

Chemical control includes the use of pesticides, repellents, insect growth regulators (IGRs), or any other chemical means of killing or repelling flies.

What to Do: Although Fly Predators will do most of the heavy lifting reducing pest fly populations, the targeted use of premise sprays and baits can help to further manage adult fly populations on key areas of the farm.

What Our Customers Say


Your IPM Questions, Answered

Integrated Pest Management (IPM) is a strategic, environmentally-friendly approach to controlling pests by combining multiple methods to reduce pest populations effectively. It incorporates biological control (using natural predators like Fly Predators), cultural control (managing the environment to disrupt pest breeding), mechanical control (such as traps and physical barriers), and targeted chemical control. The goal is to break the pest life cycle while minimizing harm to your animals, your property, and the environment.

Fly Predators are tiny, non-stinging parasitoid wasps that naturally target and eliminate fly pupae before they can hatch into adult flies. By breaking the fly life cycle at its source, Fly Predators reduce fly populations significantly over time. Simply sprinkle them near manure piles, compost heaps, or other areas where flies breed, and they’ll do the rest. Fly Predators are species-specific, meaning they won’t bother you, your animals, or beneficial insects.

Absolutely. Fly Predators are a natural, eco-friendly solution for controlling fly populations. The species we use are native to North America and specifically target pest flies without affecting humans, animals, or other beneficial insects like bees and butterflies. Plus, Spalding Labs carefully selects only the most effective species, ensuring safety and efficiency while reducing the need for harsh chemicals.

The number of Fly Predators you need depends on the size of your property, the number of animals you have, and the amount of manure or organic material where flies breed. Spalding Labs takes the guesswork out by providing personalized recommendations based on your unique situation. You can use the Fly Predators Calculator on our order page or speak with one of our experts for more guidance.

Fly Predators are most effective at preventing fly populations from growing, so they work best when implemented early in the season. If you’re already dealing with a fly problem, we recommend combining Fly Predators with other IPM components, like traps to catch adult flies and Bye Bye Insects fly spray for immediate relief. Over time, Fly Predators will reduce future fly generations, providing sustainable long-term control that gets easier over time.

WOW! What a difference! I have been getting your fliers for a while but some clients finally convinced me to buy Fly Predators. I have recommended them numerous times and will continue to!
Shelby L.Hidden Acres Equine and K9, Endicott, NY
This was my first year using Fly Predators. After having a HUGE issue with them last year, so bad you couldn't be outside with out getting swarmed by them, I had to do something... A friend recommended using Fly Predators. They have made a HUGE difference and I will never go another year without them!!!
Jennifer T.Supercharge Performance Horses, Cedar Springs, MI
This is our 4th season using Fly Predators and we are seeing a huge improvement. We have not had to put any fly masks or sheets on the horses as of yet and they were normally covered with them by now.
Lisa C.Heringo Labradors, Endicott, WV
I have had my dog kennel for 17 years and have tried a lot of different products and have felt up until now that I have wasted my money. When I received my first shipment of Fly Predators I was skeptical now I am just amazed. The ease of application is a major plus. I hardly ever see a fly and my dogs are very happy.
