New Insecticide for Termite Control In many parts of the world, wood struc- tures and products must be protected from subterranean termites. Until recently the only insecticides known to provide reliable long-term protection when applied to the soil around and under structures were the chlorinated hydrocarbons aldrin, chlordane, dieldrin, and heptachlor. Controversy over the use of these materials has led Southern Station scientists to search for alterna- tive termite control chemicals. What was needed was a safe chemical that would stay in the soil where it was placed, preventing termites from pass- ing through the soil and into a structure. In long-term field trials, just such a chemical was identified. Called per- methrin (Pounce®), the material is a synthetic pyrethroid. It has performed very well in field trials, and it has been registered by the Environmental Protec- tion Agency for use against termites. Among registered termiticides, it has the lowest mammalian toxicity. Pounce is only the fourth termiticide to be reg- istered in over two decades. In addition to proving out the new insec- ticide, Forest Service termite research workers have improved the popular bul- letin on biology and control of termites. Home and Garden Bulletin 64, "Subter- ranean Termites—Their Prevention and Control in Buildings," tells how to recog- nize termites and their damage and how to prevent that damage. All-new color photographs and illustrations make the subject easy to understand. This bulletin can be purchased from the Superinten- dent of Documents, Government Printing Without control, subterranean termites can make short work of wood on or near the ground. 2k. Pleas
