Pest repellents are provide that contain a pest repellent composition comprising carane-3,4-diol as an active ingredient, a non-porous round polyethylene powder, and a solvent. Preferably, the provided pest repellent compositions comprise (i) about 3-50% by weight of carane-3,4-diol, (ii) about 3-30% by weight of a paraffin, (iii) about 20-90% by weight of an alcohol and (iv) a non-porous round polyethylene powder, wherein the amount of the non-porous round polyethylene powder present in the pest repellent composition is about 0.05 to 1.0 times the weight of carane-3,4-diol present in the composition. Aerosol pest repellents are also provided.

Pest repellent composition

An ectoparasite-controlling agent for animals comprising 0.1 to 20% by weight of the neonocotinoid compounds defined in the specification and 10 to 95% by weight of a glycol or glycol monoalkyl ether has an excellent effectiveness by the application methods such as spot-on and pour-on application.

Ectoparasite controlling agent for animals

An insecticidal and acaricidal smoke fumigant formulation obtained by mixing granules A having a bulk specific gravity of 0.3 to 0.9 and containing a pyrethroid compound as an active ingredient, an inflammable substance and an organic blowing agent, with granules B having a bulk specific gravity of 0.5 to 1.1 and containing potassium perchlorate, potassium nitrate and/or potassium chlorate, burning agent, heat generation-regulating agent, perchlorate-decomposing aid and inorganic filler, the mixing ratio (weight ratio) of the granules A and the granules B being 1 to 0.5-4.

Insecticidal and acaricidal smoke fumigant compositions

The insecticidal composition of the present invention contains (a) 2,4-dioxo-1-(2-propynyl)-imidazolidin-3-ylmethyl chrysanthemate and (b) at least one carboxylic acid ester selected from the group consisting of monocarboxylic acid ester having 16 to 19 carbon atoms and dicarboxylic acid ester having 16 to 19 carbon atoms, the weight ratio of (a) to (b) being from 3:1 to 1:100.

Insecticidal compositions

An insecticidal composition characterized in that said composition contains 3-(2-methoxyphenyl)-5-methoxy-1,3,4-oxadiazol-2(3H)-one and at least one of the pyrethroid type compounds represented by the formula, ##STR1## which has a remarkable synergistic action in both the rapid knock-down effect and high lethal effect.
