What is the rain fast information with Butox Swish?
MSD Animal Health has undertaken a field study1 to see how the efficacy of Butox Swish might be affected by rainfall. A group of treated animals were wetted thoroughly with water, twice weekly, over a 4-week period. Midges were then placed in contact with the hair from these animals. Even after 4 weeks of rainfall the midges were still killed, even with as little as 15 seconds exposure to treated hair.
The study confirms that Butox Swish remains effective on animals regularly exposed to rain - not an uncommon event during the UK summer!
