An insect repellent patch is disclosed of a size and weight compatible for wearing on the clothing or skin of a user. The patch has a gross area not in excess of 232 cmand bearing one or more insect repellents having a vapor pressure at 25&#xb0; C. of not less than about 1&#xd7;10mm Hg. The total amount of insect repellent is in an amount effective to provide practical mosquito personal area repellency. Kits of such patches, with instructions for use, and methods of providing practical personal area insect repellency are also disclosed.

Methods determine how effective a product that dispenses an insect repellent or insecticide is in controlling flying insects such as mosquitoes, with no or reduced need for human test subjects. An insect trap or other automated monitoring device is positioned in a test environment and operated in a manner so as to mimic some human attribute (e.g. by dispensing carbon dioxide). Trap/monitoring results in the presence and absence of the operating product are obtained in order to judge relative effectiveness of the active. Further, the real time evaluation of insect populations permits evaluation of time needed to achieve base effectiveness and length of time that effectiveness can be sustained.

Methods for testing insect control products

Disclosed herein is two-stage mat for dispensing volatile materials. The mat is comprised of two materials varying either in thickness, thermal conductivity and/or porosity (and coated with like volatile material), or coated with volatile materials having different vaporization pressures. In either configuration, the mat provides for both an instant burst of volatile and then a sustained vaporization of volatile. Methods of using such mats are also disclosed.
