Advantages:
(1) The insecticidal formula of mosquito-repellent incense can be adjusted at will, and mosquitoes are not easy to adapt, and the mosquito repellent effect is good;
(2) The insecticide is evenly distributed on the mosquito-repellent stick, and gradually heated, so that the insecticide is evenly dispersed, the mosquito repellent effect is stable, and the KT50 value remains unchanged;
③ No power supply is needed; The price is cheaper.
Disadvantages:
(1) cannot guarantee a fixed service time;
(2) There are harmful components in the smoke of wooden mosquito-repellent incense, which pollutes the space environment and articles.
(3) Open flame ignition, a potential fire hazard;
(4) When the mosquito-repellent incense is ignited, the pesticides in the mosquito-repellent incense can't be dispersed in time (especially the disc-type mosquito-repellent incense produced by traditional technology), and about 30-40% of the pesticides are decomposed by heat and lose their mosquito repellent effect.
2, electric mosquito coils
Advantages:
① Smokeless, odorless, ashless and pollution-free;
② PTC heating source is safe and hygienic.
Disadvantages:
① The mosquito repellent effect is unstable, and the effect is better in the first 4 hours. After 4 hours, the mosquito repellent effect gradually decreased;
(2) The pesticide formula cannot be adjusted at will, and mosquitoes are easy to adapt to a single pesticide formula;
(3) The decomposition rate of pesticides is high when the paper is heated for a long time;
(4) After the paper base is used, there are still 20-30% pesticide residues, which lose the mosquito repellent function and cause waste.
3, electric liquid mosquito-repellent incense
Advantages:
① Smokeless, odorless, ashless and pollution-free;
② It is safe to use PTC heating source;
③ It can be used at any time, and it is very convenient to send power when it is used and cut off power when it is not used.
Disadvantages:
(1) Because the boiling points and vapor pressures of the components in the agent are inconsistent, they can't evaporate synchronously when heated, resulting in the blockage of the mandrel. Therefore, with the increase of use time, the evaporation of drugs gradually decreases, and the efficacy of mosquito repellent also decreases;
(2) The formula of medicine can't be adjusted at will, and mosquitoes with single formula are easy to adapt;
③ The decomposition rate of pesticides is about 30-35% during use, and there is 5%- 10% pesticide residue on the mandrel after use, which greatly reduces the utilization rate of pesticides and causes waste;
④ The solvent is deodorized kerosene, which is difficult to seal and easy to leak. Kerosene is dangerous, so pay attention to safety.
