Abstract
An insect repellent is suitable for an anti-tick treatment to living materials such as bedding and carpets with long-term replacement cycles in years and that also has a tick repellent effect stably lasting over a long period of time. The insect repellent contains 2,4-DHAP or xanthoxyline as an active ingredient. 2,4-DHAP and xanthoxyline can stably maintain repellency rates of at least 30-40% and about 90% respectively even if a heating treatment at 150° C. is continued for 5 minutes or longer, that is, for about 3 years in an environment of 25° C.
