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)

Perfect Navy Clutch!
Color: Navy
The Navy Blue clutch is really nice with a goldtone clasp and a really nice goldtone twisted rope chain that's detachable. The chain alone makes the purchase worth it to interchange onto other clutches that came with cheesy silver tone cheap-looking chains. It's roomy enough to hold your bulky cell phone, a small brush and some makeup plus a zip pocket for money (what's that?), ID, and credit cards. One of the best purchases I've ever made. Attractive and classy clutch!

Lovable clutch
Color: Navy, Color: Navy
Cute clutch for events. Took to a wedding, nice size, especially like that I could put my phone in it and plenty of room for a small wallet, lipsticks, and tissues/personal products.
I wish the fabric were higher quality (has a sheen to it yet it is thin) but for the price it makes sense. I will only use for special occasions.
Once aired out overnight, it had no smell. Very light in weight.
It has a strap that would make it more comfortable to lug around, but I think I lost it? That is on me! I appreciate that it has a strap and a place for it to convert.
Overall super happy and does the job! Carries everything I need for formal events.
Photos show one with my hand and one with a lipstick in it for size reference. Other shows a thoughtfully placed zipper pocket that is convenient!

Beautiful and trendy especially with minor adjustments!
Color: Red, Color: Red
The satin fabric of the bag is of great quality. Thick and resistant to snags. I partied all night with it and it held up beautifully. The color saturation of the red was perfect and against my dark dress was a perfect pop of dramatic color contrast.
Notes: The magnetic closure is strong but doesn't form a complete closure because there are only two magnets. Don't turn the bag upside down or small items can fall out. There was a strong chemically smell that dissipated after a week of airing out and adding a few drops of perfume to a tissue that I kept inside the bag.
I wanted a "dumpling" clutch so I altered it slightly. First I colored over the gold closure with nail polish to match the fabric color. There is something about the gold tone that detracted from the elegance. Then I added a stitch to the bottom and top corners to round the shape a bit. See pics I can hardly sew on buttons so if I could do it, anyone can! The fabric is well lined and has just enough structure to it to hold the dumpling effect without becoming too slouchy looking.
The chain is nice with more elegant looking clasps than other similarly priced bags, but I didn’t use it because I wanted a clutch. Under my arm or in my hand as a clutch this was light and comfortable.
Got lots of compliments and questions about where I got it. Overall a fantastic buy.

Roomy, Quality and Versatile
Color: Navy
Very nice quality and appearance. Large enough for wallet, phone, etc. Easily converted from clutch to shoulder purse with removable chain. Handle trim and chain are gold color. Wish it silver but very pleased overall and feel it is a good value.
