Inside an Indian mosquito plug-in vapouriser/vaporizer.

The best place to get a proper plug-in mosquito control device is a country that actually has a mosquito issue. This rather neat dual power level vapouriser (British spelling of vaporizer) came with two large bottles (normally just one) of liquid based on:-
Transfluthrin 1.6% A refined version of a natural plant pyrethroid. (Plant's own insect protection.)
Butylated hydroxytoluene 1% A food certified additive that prevents oxidation of oils.
Goodknight-05 1% Mystery proprietary ingredient. Possibly a pyrethroid blend.
Deodorised Kerosene 96.4% carrier oil to give controlled release and dispersion.

We don't really have a mosquito problem on the Isle of Man, although we do have the blight of midges (tiny biting flies) that thrive in moist climates and tend to come out once the sun goes down and take a bite out of any passing creature.

The bit that interested me was the transfluthrin. A synthetic pyrethroid based on a plants own natural defence systems. (Notably the chrysanthemum species.) The plant pyrethrins have been used for thousands of years as natural insect repellents and the modern synthesised variants are considered one of the safest and most effective insecticides.

The toxicity to humans and animals is low, but usual care should be taken to prevent children and pets making contact with the raw chemicals.

One of the most common uses of transfluthrin in the UK is moth control. If moths find their way into areas where fabric is stored they will lay eggs on loose strands of material in dark and protected areas. The resultant larvae hatch out and ingest any frayed fabric they can find. Usually wool, fur and cotton, but they can also damage synthetic fabrics through indiscriminate testing of materials. The best approach to avoiding moth issues is to prevent them happening in the first place, so a slow release moth repeller in fabric storage areas can save grief later. Newly acquired "vintage" clothing can be tumble dried to kill any hidden eggs with heat. (Your clothes dryer is a great fabric steriliser.)

Here's a generic eBay search link to a variety of Good Knight products from India. Note that their mains voltage is 230V. The double setting PTC-based unit I took apart does seem to accommodate 120V use. Price varies wildly, so shop about.
