Intrigue Dust - A new method of eradicating subterranean termite (Isoptera: Rhinotermitidae) colonies
2001 - IRG/WP 01-10396
Arsenic trioxide is used by pest controllers in Australia to eradicate subterranean termite colonies. In 2000 Bayer Australia introduced Intrigue Termite Dust as a more environmentally acceptable alternative. Intrigue, containing 80% triflumuron, a chitin synthesis inhibitor, disrupts the moulting process in termites. Dusted termites return to the nest and pass around triflumuron via mutual groomi...
