Additionally, the water-based formula is a plus for those looking for easy cleanup and less sticky residue. Its weatherproof properties mean it will remain effective even in less-than-ideal conditions. The inclusion of sunscreens and coat conditioners is a thoughtful touch, providing additional care for your animals' coats while protecting them from bugs and UV rays.

However, potential users should be aware that, while the product is powerful, it might not be the best option for very sensitive areas or animals with particularly sensitive skin. For those looking for a comprehensive and long-lasting insecticide, Absorbine UltraShield EX offers a wealth of benefits. It is particularly well-suited for horse owners who need a reliable, weatherproof solution with added coat care benefits.

The 1-gallon bottle offers a ready-to-use formula, making it convenient for immediate application. One of its notable strengths is the inclusion of citronella, which provides a pleasant scent compared to other sprays with harsh chemical odors.

The product’s strong effectiveness is well-reviewed by users, earning a 4.7 out of 5 stars from nearly 1,900 ratings, indicating high satisfaction. Additionally, it is safe for use on all age ranges and is free from common allergens like celery, ensuring the safety of your horse.

Weighing 7.1 pounds, the bottle is relatively heavy, which could be cumbersome during application. The Pyranha Wipe N'Spray is a reliable choice for most horse owners.

The product uses 7 essential botanical oils, offering a natural alternative to chemical-based sprays, which is great for daily use on horses, ponies, and dogs. The water-based formula ensures it can be applied frequently without concern. However, the product does not come with a sprayer, which may require purchasing an additional tool for application. Its citronella scent, while fresh, might not be pleasing to everyone.

The repellent is effective against various pests including flies, mosquitoes, ticks, and gnats, though some users may find they need to reapply more often compared to other longer-lasting sprays. It is safe to use on sensitive areas, which is a significant advantage for pets with delicate skin. At 128 ounces, it provides a substantial quantity, ensuring it lasts a while even with daily use. Given its natural formulation and safety, this spray is ideal for pet owners looking for an environmentally friendly and sensitive-skin safe option, though they should be prepared for potentially more frequent applications and the need to buy a separate sprayer.
