Insecticide is refused, insect repellent for the skin is not

The lists separate a product sprayed at insects from one applied to the skin, and only the first is treated as a toxic substance.

Listed among household chemicals
The Japanese list puts insecticide in its table of liquids, in the run of household chemicals that follows bleach and mould remover, with a cross for both carry-on and checked baggage. Smoke-type insecticide has a row of its own under daily goods, crossed out the same way. Neither row gives a quantity or a size that would pass.
Repellent for the skin is a different item
Insect repellent, liquid or spray, sits in Japan's medicines table beside bite and itch remedies and may be carried and checked within the quantity limits. CASA's entry Insect repellent, fly spray, bug spray applied to the body is allowed the same way, while its household aerosols category, with bug spray as an example, is marked Item Not Permitted.
Narita's answer to a student taking insecticide abroad
Narita Airport's FAQ takes a passenger who wants to bring insecticide to a study abroad destination. The answer names a product: any kinds of insecticide, such as Varsan, which contains toxic substances, are prohibited in carry-on baggage and checked baggage.
Australia's list reaches mothballs and gas-cartridge repellers
CASA goes beyond sprays. Camphor blocks, naphthalene or mothballs are marked Item Not Permitted, and so is weed killer. A Thermacell mosquito repeller, like similar camping lanterns containing gas cartridges, is forbidden under the category for flammable gas fuel.
