The efficacy of dieldrin as a protection against the wool destroying insects. Anthrenus flavipes Lec. (wooly bear) and Tinea pellionella Linn. (case bearing clothes moth) has been investigated. In very low concentrations (0.02-0.05percent on the weight of fabric), the insecticides offers adequate protection against both the insects. the effectiveness of treatment is not impaired by laundering (12 times) or dry-cleaning (12 times). The resistance to laundering and dry-cleaning is not, however, as satisfactory when the insecticide is applied from solution. The economics of utilization of dieldrin as a protectant against the wool destroying insects has been discussed in relation to DDT, and it is shown that the former insecticide is much less expensive.
