I'm not one to leave a review unless I'm super pleased or something is really NOT as expected or advertised. So this is a positive scale review. Wow, amazing! That's all I can say. We have been feeding this product for a year now and it absolutely works! We have noticed a significant decrease (to almost 0) in the number of flies at our place. We live in the Houston area and flies are always a problem. We have multiple horses and used to go through gallons of fly spray. Tried all different brands with the same results; plenty of flies... However since starting MultiFly, all that has changed. We actually have people who come to our place comment on the LACK of flies. If your on the fence, jump off of it because this stuff actually works. Just make sure all the horses in your facility are on it. Pretty sure if they're not you won't get these kinds of results.

Description:

Our MultiFly pellets provide safe and effective fly control for your barn. Simply feed once per day to break the fly life cycle. MultiFly is made with Novaluron, which is a completely safe Insect Growth Regulator and is 99.9% effective.

As existing adult flies die off, the overall fly population is significantly reduced within 2 weeks upon feeding MultiFly. Start feeding in spring before flies begin to appear. The product should be used as part of an integrated pest management program and should be used throughout the fly season. Novaluron is not an organophosphate, and can be safely used in a pest control program for horses and their environment.

The fastest way to enjoy fewer flies in your barn.

Flies are not only a nuisance, but can transmit diseases to your horses. MultiFly Feed-Thru Fly Control is one of the most effective fly control solutions on the market, at the cost of only $0.36 per day per horse. This safe, pelleted formula provides 99.9% efficacy at breaking the fly life cycle in the manure of treated horses. Simply feed to your entire barn, and watch the fly population quickly shrink.

Step 1: Give MultiFly to each horse in the barn daily with grain

It's important to feed every horse in your barn to see the best effects. Simply feed alone, or with grain. One scoop/day is sufficient for the average-sized horse.

Step 2: Horses eat MultiFly and expel it in their manure

The active ingredient in MultiFly, Novaluron, is a completely safe ingredient for horses. It is not absorbed by the horse, but rather is passed through the digestive tract, into the manure.

Step 3: Manure produced by horse is no longer a viable breeding ground for flies.

Fly eggs that are laid in treated manure will die before developing into flies.

Which fly species does MultiFly target?

MultiFly Feed-Thru Fly Control for Horses specifically targets the common types of flies that reproduce in manure, aiming to interrupt their life cycle and reduce their population. These flies include the housefly (Musca domestica) and the stable fly (Stomoxys calcitrans). It is important to note that certain species of flies, such as the horse fly and deer fly, do not reproduce in manure but rather lay their eggs near water sources or moist areas, like marshes or ponds. Many of our customers with water sources nearby use Fly Predators in tandem with MultiFly. These can help target flies that are reproducing in breeding sources that are not manure. MultiFly Feed-Thru Fly Control focuses on the fly species that rely on manure for reproduction, making it an effective solution for controlling these specific types of flies.

Why use a feed-thru fly control?

1. Shrinks the overall fly population

While fly sprays can be useful, and we recommend them being used in conjunction with MultiFly, they don't tackle the root of the problem. MultiFly helps cut down the overall number of flies, lessening your dependence on fly sprays.

2. Reduces the risk of fly-borne equine disease transmission.

Using fly spray alone can be a pain to apply to each horse daily. Even fly sprays that are longer-lasting can be affected by sweat, water, and dirt. MultiFly is as simple as a scoop/day with your horse's normal grain.

3. Easy to administer.

Flies can carry dieseases such as Pigeon Fever and Equine Infectious Anemia (EIA). Fly control is an important piece of helping to protect your barn.

4. Makes a more enjoyable environment for you too!

No one like seeing their horse suffer from swarms of biting flies, but it's also not pleasant for you and anyone that is around your horses. MultiFly can help make your barn more pleasant for everyone who visits.

MultiFly breaks the fly life cycle so that adult flies can't form

What is in MultiFly?

Novaluron is the Insect Growth Regulator (IGR) used in MultiFly Feed-Thru Fly Control. All feed-thru fly control products on the market have an IGR. An IGR is an active ingredient that works to disrupt the normal life cycle of the insect.

 

Not all IGR's are created equal. Some IGR's used in feed-thru fly control products are organophosphates. Organophosphates are pesticides that are especially toxic to both mammals and insects.

 

Novaluron, on the other hand, is a minimal-risk IGR that is not an organophosphate. In a 2015 study, it was shown that Novaluron was 100% effective in preventing the development of house flies and stable flies in the feces of treated horses.

Working well in NW FL

Flies were an annoying part of having back yard horses here in NW FL. Since using this product there has a notable decrease in the number of flies bothering my 2 horses, now if we could just get rid of the gnats.

707 Multifly has been a lifesaver here at our ranch in Texas.

We have been using707 Multifly for about 2 years now at our ranch in East Texas. I hear and see lots of complaints about a terrible fly season but not for us!! Our horses and cows hardly ever have to be sprayed for fly's. We also have chickens and 6 dogs. We love to sit outside on the patio and enjoy morning coffee or an evening beverage, that is absolutely possible and quite pleasant since starting 707 Multifly!! Highly recommended

I used this product all last summer. It has definitely worked. I have already ordered more to start up in the early spring. I do recommend this product to help with or eliminate your fly problem.

Great product!

I have been using multifly for two years now. It is a safe and very effective product that makes a huge difference. I have an animal sanctuary/rescue, and we have over 12 equines. Multifly dramatically reduces the flies on our property. I highly recommend it.

Frequently Asked Questions

My dog eats manure. Will my dog be safe if he consumes manure when I am feeding MultiFly to my horses?

We have many MultiFly customers with pets that like to eat manure. However, we are not able to make any claims regarding safety/efficacy for any other animal other than horses. With that being said, Novaluron (the active ingredient in MultiFly) has undergone rigorous safety and efficacy studies in other species for different applicat
