| 摘要 |
The present invention relates to a method of controlling insect infestation whereby an insecticidal coating having an extended residual period of a few months to a year is applied to a surface. A removable cover may be positioned near the surface to create a substantially darkened region to exploit some insects' natural tendencies to hide in dark places during daylight hours. Alternatively, the insecticide may be applied prior to the hatching of the insect eggs to control the population upon hatching. The method is especially effective for controlling the presence of gypsy moth caterpillars on trees. The present method may be accomplished by covering a portion of a tree trunk with an insecticidal coating containing an active ingredient such as chlorpyrifos, pyrethroid, permethrin, or tralomethrin and covering the coated area with burlap. In addition, the method of the present invention can be used to control the presence of insects on the sides of houses or other structures.
