3. What Chemical Is Used for Mosquito Fogging 

For mosquito fogging, a few different chemicals can be used: 


This is a well-known insect killer that’s been around since the 1950s. It’s often used in farming to keep pests away from crops and is also used for large-area mosquito control. 


Similar to malathion, naled is very effective at killing mosquitoes.

But it’s powerful stuff and can also harm birds and fish, so it’s important to use it carefully, especially around water and where wildlife is present. 


This is a natural bug killer that comes from chrysanthemum flowers. There are two kinds, pyrethrin-I and pyrethrin-II.

Pyrethrin-II is what you’ll commonly use in household foggers, while pyrethrin-I is for professional use only.

Pyrethrin attacks the nervous system of mosquitoes, making it a very effective choice. Plus, it breaks down easily in the environment, making it a more eco-friendly option.


These are man-made chemicals that mimic natural pyrethrin. They include deltamethrin, permethrin, resmethrin, and sumithrin.

Pyrethroids stick around a bit longer than natural pyrethrin and aren’t as sensitive to light, which means they can keep protecting against mosquitoes for a longer time.

4. Is Mosquito Fogging Harmful to Humans? 

Mosquito fogging is a widespread technique for reducing mosquito numbers. The World Health Organization (WHO) has indicated that this practice is usually safe for humans.

The insecticide in the fog is much like what you’d find in household bug spray cans available in stores. The concentration of insecticide in the fog is very low, designed to be deadly only to tiny insects like mosquitoes, so it’s not expected to harm people who are only exposed to it now and then. 

However, if you’re around the fog a lot and don’t protect yourself, it could be bad for your health, potentially causing issues like poisoning, asthma, bronchitis, or even lung cancer over time. So it’s wise to keep away from the fog if you can and take safety measures like wearing protective gear or staying inside when fogging is happening.

5. How Much Time Should Elapse Before Going Outdoors Following the Use of a Mosquito Fogging Machine? 

After using a mosquito fogging machine, the time you should wait before going outside varies based on the specific product you’re using. Generally, a wait of 15 to 20 minutes might be enough. However, there are situations where you might need to wait for at least an hour. 

The type of insecticide or pesticide in your fogger really determines this waiting period. The best thing to do is to look closely at the label and follow the instructions on your chosen solution to understand how long you should stay out of the treated area.
