Review: Shoo fly! - Works ok for a little while. Flies are a nuisance!
Review: BEST. FLY SPRAY. PERIOD. - This is more expensive on the outset when compared to water based fly sprays, however, it is more economical in the long run because it is a superior fly spray that works with much less product being sprayed on my horse. It sticks and the flies avoid it completely. I’ve used 1/2 bottle of this spray as compared to 2 full bottles of water based sprays. Excellent fly spray and the only one I buy now. 5 stars.

## Questions & Answers

**Q: can this be used on dogs?**
A: It's all I use on my dogs for ticks, fleas and flies. They're both full time outside dogs and the fly repellent is a must. We've also never had any issues with fleas or ticks.

**Q: Could this be sprayed on the yard and on concrete? We have a backyard bar area.**
A: Sure. I don’t see why not. Keep it away from food. I would probably look for a yard spray though. This is kind of expensive for that purpose.

**Q: Does amazon honor coupons on this product?**
A: It would need to be an Amazon specific coupon. If it's one from the Farnam website no, those cannot be used on Amazon.

**Q: How often can you spray your horse with this?**
A: Hello. According to labeling information the spray should be applied every 5-7 days under normal conditions for initial applications. As protection builds reapply every 10-14 days as needed and reapply each time animal is washed. I hope this is helpful.
