A point source insect control device which comprises a frangible container poorly permeable to gases and liquids containing a liquid insecticidal substance capable of translocation;
- a sheet of absorbent material at least one portion of which at least partially surrounds or is in close proximity with said container;
- and an enclosure for said container and said absorbent sheet;
- said enclosure bearing multiple perforations or apertures sufficient to allow translocation of said insecticidal substances once said frangible container is ruptured.
A method of controlling insects at an enclosed locus which comprises placing in said enclosed locus one or more point source insect control devices each comprising a frangible container poorly permeable to gases and liquids containing a liquid insecticidal substance capable of translocation;
- a sheet of absorbent material at least one portion of which at least partially surrounds or is in close proximity with said container;
- and an enclosure for said container and said absorbent sheet;
- said enclosure bearing multiple perforations or apertures sufficient to allow translocation of said insecticidal substances once said frangible container is ruptured;
