As a commonly used tool for household pest control, the applicable population of insecticidal Aerosol Cans needs to be comprehensively evaluated in combination with the product characteristics and health risks. Although modern products mostly use low-toxicity or slightly toxic hygienic insecticides (such as pyrethroids), the physiological characteristics and application scenarios of different groups of people vary significantly, and targeted protection strategies need to be selected.

Ordinary healthy adults: The first choice for short-term emergencies

For adults without chronic diseases and with normal immune systems, insecticidal aerosol cans are highly efficient tools for quickly eliminating mosquitoes, flies and cockroaches. Its advantages lie in its rapid effect (visible within 3 to 5 minutes) and wide coverage, making it particularly suitable for sudden pest infestations or temporary activity sites (such as camping tents and warehouses). However, it is necessary to strictly follow the operation specifications: Evacuate immediately after spraying, keep the area well-ventilated for more than 30 minutes, and avoid continuous exposure for more than 2 hours. If you are in an environment with a high incidence of pests for a long time, it is recommended to give priority to using Electric mosquito repellent liquid or physical pest control methods (such as window screens and sticky boards) to reduce the accumulation and exposure of chemical agents.

Special groups: Use with caution or avoid using

Pregnant women and infants: The nervous systems of fetuses and children are not fully developed and are sensitive to pyrethroid components. Research by the US Environmental Protection Agency (EPA) shows that long-term exposure by pregnant women may increase the risk of abnormal fetal behavior, and infants and young children who inhale it are prone to allergic reactions such as coughing and rashes. It is recommended that such people use physical insect control methods (mosquito nets, long-sleeved clothing) or plant-based mosquito repellent products (such as sprays containing less than 10% picaridin).

People with asthma and allergic constitutions: Organic solvents in aerosols (such as propane and butane) may induce airway spasm and aggravate asthma symptoms. People with allergic constitutions may experience reactions such as eye congestion and skin itching after contact. If it is necessary to use, an N95 mask and goggles must be worn. After spraying, thoroughly clean the contact surface.

The elderly: The decline in liver and kidney functions leads to a decrease in metabolic capacity, making them prone to mild poisoning symptoms such as dizziness and fatigue. It is recommended to reduce the frequency of use, give priority to low-residue formulas (such as water-based aerosols), and avoid spraying in a closed bedroom.

Principle of scientific use: Reduce health risks

Choose compliant products: Make sure to recognize the "three certificates" (pesticide registration certificate, production license, and product standard number), and avoid purchasing "three-no" aerosol cans. Give priority to products containing natural plant ingredients (such as tea tree oil, lemon eucalyptus leaf oil) or slightly toxic pyrethroids.

Control the dosage and frequency: Spray for no more than 10 seconds per 10 square meters of space and use no more than twice a week. Avoid spraying near tableware and food. After spraying, wipe the surface of furniture with a damp cloth.

Storage and disposal safety: Aerosol cans should be stored in a cool and dry place (temperature < 45℃), away from fire sources and children. Expired or damaged tanks should be handed over to professional institutions for recycling. Do not puncture or burn them.

The applicability of insecticidal aerosol cans should be based on the premise of "health first". Ordinary adults can use it for short-term emergency purposes, but sensitive groups such as pregnant women, infants and young children, and patients with chronic diseases should avoid it as much as possible. Only by combining physical pest control, environmental cleaning (such as sealing gaps and reducing water accumulation) and chemical control can a safe and long-lasting pest control system be established.
