[0004] In the pest control composition, it has been required to have a longer-term control effect. Therefore, an object of the present invention is to provide a pest control composition that exhibits a pest control effect over a longer period.

Means for Solving the Problems

[0005] As a result of intensive studies to solve such problems, the present inventor has arrived at the present invention. That is, the present invention provides: [1] A pest control composition containing permethrin, bomethrizole, and a paraffinic saturated hydrocarbon. [2] The above pest control composition further containing a mixture of bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate and methyl(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate. [3] An aerosol agent containing the above pest control composition and a propellant. which are provided.

Effects of the Invention

[0006] The pest control agent of the present invention makes it possible to control pests over a long period of time. [Modes for carrying out the invention]

[0007] The permethrin content used in the pest control composition of the present invention is typically 0.01 to 6.0% by weight per total amount of the composition.

[0008] The bumetrizole content used in the pest control composition of the present invention is typically about 1 to 15% by weight relative to the weight of permethrin.

[0009] Examples of paraffinic saturated hydrocarbons used in the pest control composition of the present invention include normal paraffinic saturated hydrocarbons and isoparaffinic saturated hydrocarbons. Of these, normal paraffinic saturated hydrocarbons or isoparaffinic saturated hydrocarbons having 8-17 carbon atoms as the main component are preferred.

[0010] Examples of the normal paraffinic saturated hydrocarbons include neothiosol (manufactured by Chuo Kasei Co., Ltd., 12-15 carbon atoms), cactus normal paraffin N-10 (manufactured by JXTG Energy Corporation, 10 carbon atoms), cactus normal paraffin N-12 (manufactured by JXTG Energy Corporation, 12 carbon atoms), cactus normal paraffin N-13 (manufactured by JXTG Energy Corporation, 13 carbon atoms), cactus normal paraffin N-14 (manufactured by JXTG Energy Corporation, 14 carbon atoms), and so on. On the other hand, examples of the isoparaffinic saturated hydrocarbons include Examples include commercially available IP Solvent 1620 (manufactured by Idemitsu Oil Co., Ltd., 9-12 carbon atoms), IP Clean LX (manufactured by Idemitsu Oil Co., Ltd., 8-13 carbon atoms), IP Solvent 2028 (manufactured by Idemitsu Oil Co., Ltd., 12-16 carbon atoms), Isopar E (manufactured by ExxonMobil Corporation, 8-10 carbon atoms), Isopar G (manufactured by ExxonMobil Corporation, 9-11 carbon atoms), Isopar H (manufactured by ExxonMobil Corporation, 10-12 carbon atoms), Isopar L (manufactured by ExxonMobil Corporation, 10-14 carbon atoms), and Isopar M (manufactured by ExxonMobil Corporation, 11-17 carbon atoms). These paraffinic saturated hydrocarbons may be used individually or in mixtures of two or more types.

[0011] The pest control composition of the present invention may further use a mixture of bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate and methyl(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate, for example, Tinuvin 292 (manufactured by BASF).

[0012] The mixture of bis(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate and methyl(1,2,2,6,6-pentamethyl-4-piperidinyl) sebacate is typically contained in an amount of 1 to 15% by weight relative to the weight of permethrin.

[0013] The pest control composition of the present invention may also contain pyrethroid compounds other than permethrin.

[0014] Examples of the aforementioned pyrethroid compounds include cypermethrin, phenothrin, cyphenothrin, tralomethrin, fenpropathrin, cyfluthrin, etofenprox, allethrin, deltamethrin, metofluthrin, profluthrin, transfluthrin, monfluorothrin, empenthrin, imiprothrin, resmethrin, phthalthrin, flamethrin, and prallethrin.

[0015] The preferred dosage form of the pest control composition of the present invention is an oil-based formulation.

[0016] The pest control composition of the present invention may also be used as an aerosol by adding a propellant. Examples of the propellant include liquefied petroleum gas, dimethyl ether, and carbon dioxide.

[0017] The pest control composition of the present invention can control pests by pre-treating areas where pests are likely to pass through or gather. For example, pests can be controlled by pre-treating areas such as the eaves, entrance, balcony, hedge, and garden trees of a house with the pest control composition. Depending on the pest species, nesting in such areas can also be prevented. Furthermore, the pest control composition of the present invention can also be used to control pests by directly applying it to them.

[0018] The pests targeted by the pest control composition of the present invention include spiders such as the golden orb-weaver spider, black widow spider, and redback spider; wasps such as the two-spotted paper wasp, black-backed paper wasp, yellow jacket wasp, European hornet, small hornet, and giant hornet; stink bugs such as the brown marmorated stink bug, the brown marmorated stink bug, and the brown marmorated stink bug; ants; moths; midges, and the like.
