Description

About Fly Eliminators:

Fly Eliminators are gnat-sized, nocturnal, burrowing fly parasites that parasitize and kill manure-breeding fly pupae (filth flies) to control adult flies. They do not bite, sting, or harm humans and animals. Larval control is one necessary step in a complete fly control program. Adaptable to all climates, these parasitic wasps develop within fly pupaes, killing the immature fly in the process. The adult Fly Eliminators' life span is dependent on temperature, but averages 3-4 weeks. Periodic releases of Fly Eliminators are recommended to keep up with the highly active female flies rapid egg laying. Expect a reduction in general fly population in four to six weeks.

Fly Eliminators are suitable alternatives to chemical fly sprays and broad spectrum insecticide use for prolonged fly control.

How To Order:

Use the pull-downs above to select the correct Fly Control Zone, number of animals, desired shipment frequency and total number of shipments you would like. Please specify if you would like to Pay-Per-Shipment in the "Special Instructions or Comments" box on the Shipping Information section of checkout. If the preset shipment dates are not to your liking, please indicate your preferred start date in the same "Special Instructions" or comments field.

When To Release Fly Eliminators:

Release when spring temperatures first arrive (after final frost date). It takes three consecutive days of 40°F weather for the overwintering fly populations to start hatching and maturing. Each female fly lays up to 1,000 eggs in her lifetime, so it is important to begin releasing the parasites early in the fly season. Released fly parasites begin parasitizing fly pupae immediately after hatching.

Continue releasing the Fly Eliminators throughout the entire fly season (until the first significant frost). It is important to release all recommended batches. The last batch may overwinter in warm climates, but should not be relied upon for fly control the following season.

Notify an ARBICO consultant if any of your conditions change, ie. you have more animals, ants are becoming a problem, or your neighbor just brought home more animals that may affect fly numbers.

Use Fly Eliminators in conjunction with EM-1 Microbial Inoculant to help break down organic matter along with good manure management.

Specialized or Custom Fly Control Programs:

If you don't see a program above that fits your needs we are happy to help you set up a custom program over the phone. Please call us to speak with one of our knowledgeable fly control consultants and customize your Fly Eliminators program. For example, if you have a dairy or poultry facility, you may need to increase the shipment frequency for successful fly control.

Pesticide Susceptibility:

Do not spray the treatment area at the same time you release the insects. If you must spray, we recommend that you spray 48 hours before or after releasing the parasites.

Instructions

The information below will help answer most of your questions about Fly Eliminators. If you have unanswered questions, please call us at 1-800-827-2847 so we can answer them! Click here for instructions in Spanish (instrucciones en español).

How & Where to Release Your Fly Eliminators:

Place Fly Eliminators nearby all potential fly-breeding areas. "Hot spot" locations include the following:

Manure and Urination Areas:
• Inside barns, stables, stalls, hospital pens, or loafing sheds
• Around corral posts. Paddock areas, along fence lines, and other frequented dropping sites
• Around the perimeters of manure piles, pits, bins, or carts
• In kennel or coop areas where manure accumulates

Watering and Feeding areas:
• Under water troughs, around barrels, buckets, or other devices
• Where spilling or leakage occurs
• Around bathing areas, drainage sites, and perimeters of run-off or stagnant pools
• Areas where feed, straw, or hay have decomposed

Other Fly-Breeding Areas:
• Around compost piles and family gardens
• Alongside garbage cans

To release, make a small hole in the ground with your shoe heel, drop in a small handful of Fly Eliminators, and cover them with straw, earth, or manure to protect them against wind, birds, ants or pesticides. Distribute them every 15-20 feet around highly active breeding sites. Use as small as a teaspoon or as large an amount as a handful. Fly Eliminators travel up to 150 feet in search of fly larvae and pupae.

Apply to as many hot spots as possible with your first application, concentrating heavily on the obvious fly-breeding areas. Repeat this release procedure in slightly different spots on subsequent applications. This will help new cultures of parasites distribute evenly throughout the fly season.

DO NOT place the parasitized pupae in standing pools of water or in the center of manure piles. Apply them around the perimeters of those areas.


Shipping Info

Standard shipping via US MAIL is included in the price of each shipment. Shipping upgrades are available, call us at 1-800-827-2847 for pricing and to make shipping method changes.

Shipment and Hatching Information:

Fly Eliminators are shipped as parasitized fly pupae mixed with wood shavings. Release small handfuls around "hot spot" fly breeding areas. Examine the clear plastic bag for insect movement upon arrival. It is time to disperse the Fly Eliminators when you see insects crawling around the top of the bag. If you do not see movement within the bag, place the bag in an old pillowcase and set it on top of your hot water heater or refrigerator. This will speed up hatching. Check them for fly parasite activity daily. Hatching can take up to 10 days to occur.

How To Store Fly Eliminators:

You will receive a shipment confirmation email with tracking information about 7 days prior to the shipment leaving ARBICO. Pick up Fly Eliminators shipments as soon as possible after delivery. DO NOT leave insect shipments in direct sunlight or areas of intense heat. Store them at room temperature (approximately 70-80°F) until they begin to hatch. Release as soon as possible after hatching fly parasites are visible.

Fly eliminator
Apr 29, 2022  |  By Raj
This works great, I wish the people across the street would use it for their horses, I have told them about it, works for our cows and pigs


Seems to work
May 23, 2021  |  By Christopher Guthrie
I'm not sure if my fly problem is just not as bad this year or if these things work that well. But there is definitely a huge difference in fly numbers this year with no other explanation. In fact, we have more animals this year than last. I did notice a healthy population of predator wasps upon arrival and pretty sure a noticable presence at dispersal areas. Even if flies would've naturally bee less noticable, these things are doing what they're supposed to, where they're supposed to. I give Arbico two thumbs up on fly control wasps! I would've given 5 stars except for the exceptionally slow response from sales staff regarding the first free sample.


i dont have a review title

We have used the fly eliminators for several years and love them! We have horses, goats and chickens and dont have flys. We had an issue 2 or 3 years ago for some unknown reason and I called Arbico and they sent another bag of eliminators immediately and the problem went away quickly.

Oct 27, 2020  |  By Julia Maruyama

I HAVE BEEN ORDERING FLY ELIMINATORS FOR YEARS AND REALLY LIKE THIS PRODUCT. IT WORKS LIKE THEY SAY IT WOULD WORK. THANKS FOR A GREAT PRODUCT


Love these little wasps
Oct 24, 2020  |  By Cat Sullivan
They really make a difference in the fly population. My two donkeys HATE fly spray, so it is really a blessing for me. I still have to use a spray during the worst of the fly season, but not nearly as often as I would without the wasps.


Just Finished Our First Year Using Fly Predators
Oct 24, 2020  |  By SHARON T HOLLAND
We have three horses, chickens, a couple of goats, five large dogs, started the year with six alpacas and traded them off for a couple of calves. So we know how manure and flies work. The flies were getting really annoying on the horses past couple of years, and it appeared the sprays we tried on them just didn't seem to last as well. We also weren't real happy about spraying an insecticide on them. In 2019 we started using Equiderma horse spray on them, which works well and no pesticides. It still wasn't quite enough. In 2020 we decided to add Fly Eliminators to address the issue. I figured if we could use one or two bottles less spray each month that paying for Fly Eliminators would be worth the experiment. By golly, they really do work! We went from spraying horses daily or every other day to every three or four days by mid year. The decrease in the number of flies was significant and amazing. So simple to every couple of weeks dropping them around as opposed to the daily spraying. A win/win situation for us and for the horses. We expect even better and faster results now that we have the fly population knocked down. Absolutely will be doing this every season from now on. If you haven't tried it, you should.


Fly eliminaters work
Sep 25, 2020  |  By Mary Rece Holt
I have been using Fly Eliminators for at least 8 years. They really cut down the fly population. I have horses and ponies that tear fly masks apart in group efforts to destroy the masks. But with Fly Eliminators I don't see flies bothering their eyes.


Fly Eliminators Work!!

The product is super helpful in reducing the number of fly's around our horses. It's great!


Yay for Predators!
Jul 26, 2020  |  By Janet Downs
Started to notice a house fly problem in my house. Got my two packs of predators and distributed to my two manure areas. Noticeable absence of flies immediately!


This is the best way get off the fly

99% fly is gone! I've been using over the 8 years now, it works well in my back yard every 2 weeks program . I ordered for my horse ranch this year . I hope it works too!!


Fly!
Jul 9, 2020  |  By Karen
I love this product, but I am not sure how well it works keeping fly away. I have used it for years, my horses are covered with fly on there legs face just all over. I have to use fly spay fly makes even fly sheets, I keep the mature cleaned up, the flies were really bad today and this evening, bugging me, I can go in an get away for awhile, but the horses deal with them 24/7. I am afraid to stop using the fly predators cause it might be even worse.


You go little fly predators! Eat em all up!!!
May 21, 2020  |  By Amy Novelli
The man who works on my horse trailer told me his wife uses part of his metal shop to fabricate the solar fly traps for ARBICO. I didnt think much of it and thought they were kind of pricey and didn't want to deal with the smell of the bait, but this year with 2 housemates living on my "Ranchito" with 3 horses, 3 dogs and sometimes chickens, the new house members were complaining a lot about the flies...we tried hauling the manure as far in the back as possible and twice a day but it kept getting worse, so i figured I would throw some money at the problem. I got one solar trap and monthly fly predators and now the comments are all about how FEW flies there are! The solar trap is filling up with hundreds, maybe thousands of died flies and the predators seem to like the wet spots where the horses urinate and i am sure they are following along with the hauled manure to the back and continuing their awesome work! Thanks, I never gave these products the time they deserved and will recommend to my whole neighborhood!


Work great

I bought the fly eliminators 2 yrs ago and took a yr off to see the difference. It was a huge difference! The flys were contributing much better and I used less fly spray


Awesome Natural Solution
May 16, 2020  |  By Carla Boyert
I love these little bugs! No chemicals near my horses or feed. I have stopped using fly strips. I was skeptical in the beginning. This is my 5th year using the Fly Eliminators.

My first shipment of fly eliminators seemed to only hatch out a few insects. I'm sure we waited long enough for them to hatch.
Owner Response: Hi Pat, We encourage you contact us if you have hatch issues with the Fly Eliminators. Since we guarantee live delivery, we will reship them if needed.


Defeat Flies
Apr 9, 2020  |  By Ann Travers
I have used fly eliminators for many years to protect my horses. It is very effective. I do have to use it in conjunction with traps and fly spray, but there has been a huge improvement before and after I used fly eliminators.

I have been on your Fly Eliminator program for I think about 9 years ,and it is amazing how well it keeps flies just gone, As long as I have horses I will use your product..


fly predators
Dec 5, 2019  |  By Sandi
prompt friendly service excellent insects, generally arrive to young to put out immediately which gives me time to fit it into my schedule. These guys really work. There are seldom enough flys to have to use fly spray on the horses.


Reliable
Nov 3, 2019  |  By Glenn R Mayer
Arbico has a user friendly website, and the orders are always sent when indicated.


Amazing!!
Jul 30, 2019  |  By Terrie Tackett
With the rain, and a renter behind me that throws his trash in the alley behind his house, the flies were so thick. I've never seen so many flies! I had tried everything, and was desperate for a solution. I read about the fly parasites, and set up a delivery plan with a very nice lady. In a month, I've noticed a 90% reduction of flies. I'm very pleased! I just discreetly sprinkle them in the alley behind my house. And Voila!


Wow!!
Jul 17, 2019  |  By Terrie Tackett
In Ohio, we have had a lot of rain. With four dogs, and renters next to me who throw their trash behind their house, I've never seen SO many flies. They would be crashing into my face when I went out in my yard. I was desperate. I ordered the fly predators, and within 10 days, there was a 90% reduction of flies!! I'm very satisfied with these little insects!!

I've used Arbico's fly eliminators for 20+ years at 3 different resort barns. Have always had awesome results! I recommend to everyone!

I have been using Arbico Fly Eliminators for several years. They work great! Hardly any flies!


Amazing
Jun 15, 2019  |  By Stacy
I have a small hobby farm and want to do right by my animals AND neighbors so I get these every year. It's amazing how well they work. I have two calves, around 20 ducks and 30 chickens as well as a dozen mini dairy goats. I order for 6-10 animals - although I am going to up it to the next level, just because, historically in my experience here, the population tends to rise starting in mid July. The fly control at the current level is very good. The customer service is fantastic and I could not be happier with this company and this particular product.

Good Product But...
Jan 23, 2019  |  By Constance Cardillo
I like the predators, but I shouldn't get messages that tell me they've shipped until they are actually shipped.
Owner Response: Hi Constance, We apologize for the inconvenience the shipment confirmations may cause. Fly Eliminators shipment confirmations always send one week prior to the actual ship date due to how we handle those shipments internally. We've done our best to note that in the confirmation email.

I have been using the Fly Eliminator program for several years on my small, 2-3 horse property. The fly population has been kept under control and, in fact, has diminished each year. I recommend this product!

I still have flies but my coach always remarks that I hardly have any flies compared to the various farms where she teaches. Plus I barely had any bot fly eggs on my horses this year.


A fly control program that works !
Jun 1, 2018  |  By David G Cheney
I've been using the little fly predators for years. A simple way to put it is, "They Work"! I'm in a very hot climate and have never had an order not hatch. The shipments are very well packaged. ARBICO staff is easy to work with and provide a high quality product that works. Lots of info on the website and well written instructions. I use the fly predator program as well as the solar fly traps. The traps work very well They are washable and sturdy and will last for years.
Owner Response: Thank you for your inputs! We are always working to improve. Glad to hear the combination of Fly Eliminators and Solar Fly Traps is working for you!

Could not be happier. Have used these for many years and last year had no flies. No need for fly masks for the first time. These combined with excellent manure management have kept the horses and us very happy.

I have been using your products for quite a few years now and or place is almost fly free. It's noticed by or friends and folks that stop by. With four horses and a pony people expect flies so it is really noticeable when they are bothered by them. Thanks for great products.
Owner Response: Thank you for the positive feedback and coming back with us!

Buy them---your horses will thank you!
Feb 9, 2016  |  By Beth and Bill
I have purchased them for a couple of years now. Even the farrier noticed we didn't have the fly population other horse owners had. That was validation for sure. I credit the fly eliminator program.


Great result

I started using the fly eliminators this spring. It made such a huge difference that I will continue to use them. Very happy with results.

I love these little guys. They do an amazing job. When everyone else's barn is full of flies I have almost none. You must have a safe place for them to grow and flourish. I have a covered bin.


Fly Parasites Work
Aug 20, 2015  |  By KKL
We have a ten stall barn and have been using fly parasites from Arbico for 12 years. The one year I forgot to order them was the only year we have had flies in our barn. Coupled with a good manure management program, the fly wasps are all you need to keep flies to an absolute minimum. Arbico reliably sends them every two weeks and they are easy to distribute. We love Arbico fly parasites!
