Abstract
Provided is a repellent material capable of maintaining a stable repelling effect for a long period of time. A pest repellent material of the present invention includes porous particles including primary particles forming pores and aggregating, and an insect repellent component present in the pores. The primary particles contain silica as a component, and in an infrared absorption spectrum of the pest repellent material, a ratio (I/I) of the maximum absorbance (I) at 3730 to 3750 cmto the maximum absorbance (I) at 1160 to 1260 cmis 0.005 or less. A contact angle of the porous particles with water is greater than 90°, and the contact angle of the porous particles with the insect repellent component is 1° to 90°. It is preferred that 2 to 5 ml of the insect repellent component is contained based on 1 gram of the porous particles.
