This natural formulation provides effective pest control without harmful chemicals, making it safe for use around pets, children, and beneficial insects like bees and butterflies. The product is pre-mixed and easy to apply; simply attach it to a garden hose and spray the desired areas.

It treats up to 5,000 square feet for fleas and mosquitoes and up to 2,500 square feet for ticks, offering substantial coverage for most yards and gardens. The spray is versatile and can be used on various surfaces, including lawns, gardens, patios, and more. Additionally, it is made in the USA and is cruelty-free, adding to its environmental appeal.

However, the product's effectiveness can vary depending on water pressure and the user's walking speed during application, which might result in inconsistent performance in some cases.

This non-greasy, fragrance-free lotion is safe for use on clothing and other synthetic materials, making it versatile for outdoor activities. It offers long-lasting protection, up to 14 hours against mosquitoes and ticks, and 8 hours against flies, gnats, and chiggers. This duration is impressive compared to many other repellents.

The lotion is designed for use by the whole family, ensuring safety for both pets and humans, which is a significant advantage for those with children and animals. Its ease of application via a pump dispenser also adds to its convenience for regular use. While the product is effective against a wide range of pests, its specific impact on fleas isn't highlighted, which may be a consideration for those specifically targeting flea infestations.

Environmentally, the product is a better option than DEET-based repellents, but users still need to follow disposal instructions to minimize environmental impact. For comprehensive protection, Sawyer recommends pairing this lotion with their Permethrin spray for clothing and gear. This product is well-suited for individuals and families who spend a lot of time outdoors and need reliable, long-lasting insect repellent.

It dries quickly and won't harm plastics or gear, which is a nice bonus if you want to apply it on clothing, watches, or other equipment during outdoor activities.

It offers long-lasting protection—up to 12 hours against mosquitoes and ticks, and about 8 hours against flies, gnats, and chiggers. This duration is quite convenient for most outdoor uses like camping, hiking, or backyard events, so you won’t need to reapply frequently. It also repels a broad range of pests, including disease-carrying ticks and mosquitoes, which is important for health safety.

The spray is safe for the whole family, including pets, which adds peace of mind. The aerosol form is easy to apply evenly, but some might prefer a pump spray to avoid inhaling mist. This repellent is a solid choice for anyone needing reliable protection from fleas and other biting insects during outdoor activities. Pairing it with clothing treatments like Sawyer's Permethrin spray can boost protection. It might not be ideal if you prefer natural ingredients or have strong concerns about aerosols, but for effectiveness, ease of use, and safety, it performs very well.
