Control of Mites on Hamsters

Abstract
Control of tropical rat mites (Ornithonyssus bacoti) without appreciable change in the physiology of laboratory hamsters (Mesocricetus auratus) was achieved by painting the tray below each cage with 2% chlordane emulsion. Freshly washed cages were sprayed with 0.3% pyrethrins- 1.5% piperonyl butoxide solution. Control on hamsters not involved in long-term experiments was achieved by dusting animals with 0.11% lindane - 1.91% methoxychlor.
