Pros

•Very effective at killing flies quickly, especially outdoors like driveways and poultry areas
•Works well in environments with frequent fly problems
•Easy to use in a spray bottle with a fine mist for targeted application
•Keeps flies off vehicles and in the driveway consistently
•Effective in pest control and provides reliable results
•Great value for the size, offering good cost efficiency
•Highly effective alround insecticide that is licensed for use
•Can be applied to clothing to repel ticks, fleas, chiggers, and other pests
•Safe to use around livestock, dogs, and chickens
•Suitable for indoor and outdoor use, including homes and animal settings

Cons

•Does not effectively keep ants away, as they reappear soon after spraying
•Many users doubt it works for ants in deep burrowing habitats, like in Florida
•Has an unpleasant odor that many find intolerable and linger hours
•Contains petroleum distillates, contributing to the strong, chemical smell
•The strong odor can be uncomfortable for users and others nearby
•Not recommended for use on cats due to potential toxicity
•Overall satisfaction with the product is low according to some reviews

Bottom Line

This insecticide is a powerhouse against flies and outdoor pests, offering quick, reliable results and good value. However, its strong, petroleum-based odor is a major drawback that may deter sensitive users. If you're primarily targeting ants or dislike the chemical smell, consider a formula with a more neutral scent or specific ant control options. For those seeking a versatile, effective insecticide for various outdoor and indoor pest problems, this product is worth a shot—just be prepared for its potent smell.
