The Fly Control for Cattle Mineral Add-Pack that Makes Keeping Flies Away Easy
- JustiFLY® Feedthrough is more effective than typical cattle fly control pour-ons for breaking the lifecycles of all four common types of cattle flies.
- This fly control mineral add-pack costs less than 6 cents per head per day.
- JustiFLY® is approved to control flies for both lactating and non-lactating cattle, as well as for use in both pasture and feedlot cattle.
JustiFLY® Feedthrough Benefits
- This fly control for cattle mineral add-pack effectively prevents the development of horn flies, face flies, house flies and stable flies in manure.
- JustiFLY® can also be used to control existing adult flies around manure.
- JustiFLY® Feedthrough can be used throughout the fly season in both non-lactating and lactating dairy cattle.
- JustiFLY® can reduce animal-handling stress.
- The fly control add-pack does not affect dung beetles.
- The fly control mineral easily passes through a cow’s system leaving no residue, requiring no withdrawal period and causing no resistance issues.
- JustiFLY® is more effective and easier to use than dust bags, ear tags, sprays, and cattle fly control pour-ons.
How to Use JustiFLY® Feedthrough
- Mix one add-pack with one 50-lb bag of free-choice mineral and feed your cattle with the mix.
- Cattle ingest the IGR larvicide as they feed on the treated mineral. It passes through the animal and starts to work on flies once it is deposited in the cattle manure.
- On average, each 360 gm. (12.7 oz.) add-pack treats 2 animals for 6 months (3 add- packs = 6 animals for 6 months)

My dog loves it!
Style: Ball, Size: Medium (Pack of 1)
This crunch ball was a Christmas gift for my 65lbs fur baby. It’s now mid April and he still loves it. He loves running after it and chomping down on it. It is still in good shape despite all the chomping it’s gotta . I highly recommend. He goes back to this toy agin and again! Great buy.

Our first babies favorite and longest lasting ball yet and he is fixing to be 7.
Style: Ball, Size: Medium (Pack of 2), Style: Ball, Size: Medium (Pack of 2)
Toughest ball we have found yet. Our doberman loves Chuckit! Balls especially the crunch one. He spreads all the balls and toys we have bought but these lasted the longest. The crunch and the glow in the dark are usually his pick but he has several different choices.

Dog toy that lasts.
Size: 5 Pack
I've got a heavy chewer on my hands, so I've basically thrown money away on countless "durable" toys that get shredded in minutes. I was skeptical about these, but the "no stuffing" design caught my eye—at least there wouldn't be fluff all over my living room!
I'm happy to report that these have actually lasted! My dog loves shaking them around and making them squeak.
The crinkle sound is a huge bonus; it really keeps him engaged.
The fact that they're lightweight makes them perfect for a game of fetch, and my dog can easily carry them around.
For the price, getting a whole bundle of these is a great deal. If you're tired of cleaning up toy stuffing, I'd definitely recommend giving these a try.

Great toy that stands up to tough dogs
Size: 5 Pack
When these toys first arrived and I opened the box I was disappointed. They seemed a bit flimsy and were not what I was expecting Boy was I wrong! My dog lived his new toy and it’s has not left his side. Best of all, it’s a tough little toy that can take a beating and keep going. My dog usually tears through his toys in a matter of hours, and I tried numerous toys over the years. I’ve tried Kevlar toys, toy that claim to be very sturdy, he always destroyed them in a matter of hours. This toy looks flimsy, but it’s soft and strong

Solid dog toys HOWEVER...
Size: 5 Pack
Got these toys for our collie-retriever. He loves them and plays with them a lot and will even get them out in the middle of the night to play with them. Since there's no stuffing you can't throw them very far but they are good for tug-of-war and really soft. The one downside, while they techically are durable and hold up to rigorous chewing, they are not impervious as our little man finally disembowled Mr. Lion after a few months of playing with him. (Serated the lining with his teeth.) Still highly recommend.
