1. The fastest and best: insecticidal aerosol. The disadvantage is that it is toxic to the human body. It is best to only use it outdoors, or after use, it is safer to open the windows for 6 to 8 hours before people can enter;
2. The safest and better effect: Electric mosquito repellent liquid. The disadvantage is that you may forget to turn it off after use, causing waste. In addition, low-end electric mosquito repellent liquid uses propargylmethrin, and mosquitoes already have a certain degree of drug resistance. Kidhope, which uses permethrin as an ingredient, is excellent in both safety and effectiveness. However, the raw material is a Japanese patent and must be imported, so the price is higher;
3. The cheapest: mosquito coil. The disadvantage is that it is choking, and the smoke PM2.5 exceeds the standard, which is harmful to the respiratory system. Irregular products may also contain banned ingredients such as DDT, and open flames may also be involved.
4. The most mediocre: electric mosquito coils. Performance in all aspects is quite satisfactory, nothing special. It is safer than aerosols and mosquito coils, but not as good as electric mosquito coils. The active ingredient content is lower than that of electric mosquito coil, and the price is higher than that of mosquito coil.
