Abstract

A pesticidal smoke producing composition comprises a heater composition capable of combustion or exothermic reaction under confined conditions together with 1, 2, 3, 4, 10, 10-hexachloro - 6,7 - epoxy - 1,4,4a,5,6,7,8,8a - octahydro-1,4,5,8-dimethanonaphthalene admixed therein, the heater composition being such that on burning or during exothermic reaction a smoke is emitted containing the naphthalene compound as a constituent. The composition, which may be in the form of a pellet, may be charged into a container having an outlet at one end through which the smoke is emitted in operation. The heater composition comprises organic combustible fuels such as hexamine or thiourea, a substance such as potassium chlorate for supplying oxygen for combustion of the fuel, and an inert substance such as china clay or talc, the quantity of the organic combustible fuel and the oxygen supplying substance being insufficient to cause excessive decomposition of the active ingredient. Preferably the combined weight of the fuel and the oxygen supplying substance is between 22 and 30 per cent of the mixture and the inert substance is between 9 and 25 per cent by weight of the mixture.
