On the other hand, examples of the isoparaffinic saturated hydrocarbons include Examples of such paraffinic saturated hydrocarbons include commercially available IP Solvent 1620 (Idemitsu Oil Co., Ltd., carbon number 9-12), IP Clean LX (Idemitsu Oil Co., Ltd., carbon number 8-13), IP Solvent 2028 (Idemitsu Oil Co., Ltd., carbon number 12-16), Isopar E (Exxon Mobil Corp., carbon number 8-10), Isopar G (Exxon Mobil Corp., carbon number 9-11), Isopar H (Exxon Mobil Corp., carbon number 10-12), Isopar L (Exxon Mobil Corp., carbon number 10-14), Isopar M (Exxon Mobil Corp., carbon number 11-17), etc. These paraffinic saturated hydrocarbons may be used alone or in combination of two or more kinds.

[0011] The pest control composition of the present invention may further comprise a mixture of bis(1,2,2,6,6-pentamethyl-4-piperidinyl)sebacate and methyl(1,2,2,6,6-pentamethyl-4-piperidinyl)sebacate, such as Tinuvin 292 (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 usually contains about 1 to 15% by weight based on the weight of permethrin.

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

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

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

[0016] The pest control composition of the present invention may be formulated into an aerosol by further adding a propellant, such as liquefied petroleum gas, dimethyl ether, or carbon dioxide gas.

[0017] The pest control composition of the present invention can be applied in advance to a place where pests are likely to pass through or approach, thereby controlling pests. For example, pests can be controlled by applying the pest control composition in advance to the eaves, entrance, veranda, hedge, and garden tree of a residence. Depending on the pest species, nesting in the place can also be prevented. The pest control composition of the present invention can also be used to control pests by directly applying it to the pests.

[0018] Pests that can be controlled by the pest control composition of the present invention include spiders such as the orb weaver spider, the black widow spider, and the redback spider, bees such as Polistes chinensis, Polistes gracilis, Japanese yellow hornet, Japanese giant hornet, Japanese small hornet, and Asian giant hornet, stink bugs such as the circular stink bug, brown marmorated stink bug, and German-winged green bug, ants, moths, and midges.
