- Carbamates, organic phosphorus compounds, and organic chlorine compounds of low toxicity have been evaluated as proofing agents for wool against larvae of clothes moths and carpet beetles. Carbamates are unsatisfactory because they cannot withstand the hydrotytic conditions encountered during application and use. Several organic phosphorus compounds are effective at economic levels, and, of these, the most durable effect is obtained by treatment with Ethyl Guthion. Organic chlorine compounds related to DDT represent the closest approach to a group of compounds that are selectively toxic to wool eating insects, since they are effective proofing agents but have relatively little effect on mammals. The choice of a suitable compound is largely dependent on durability and economic considerations. The application of Dilene (DDD or TDE) at the boil is effective and durable at levels costing a penny per pound of wool.
