  • Use of electromagnetic fields to affect insect movement
    Patent number: 7712247
    Abstract: Disclosed are methods for affecting movement of an insect with respect to a specified location. One generates an electromagnetic field adjacent the location and exposes the insect to the field. Preferably the insect is a crawling insect such as a German cockroach, earwig, firebrat, or a silverfish. To attract insects, the strength of the field is not so high as to be repulsive to the insect, yet sufficiently strong as to be attractive. Such field generators are preferably incorporated into insect traps and insect bait stations.
