How Long After Mosquito Spray Can You go Outside? 

Pesticides are used originally to kill the pests which attack a crop and prevent it from growing. Pesticides have in them the chemicals which are very harmful to pests and hence, eliminate them. It is used by many people and in controlled amounts. Because of this usage, people haven’t experienced any side-effects in human beings.

Pesticides are also used for keeping away mosquitoes. In a way, they are also pests that can attack us and cause various deadly diseases. However, compared to the amount used for killing pests in an agricultural field and the same in a domestic household, it is far lower. Any adverse health issues and side-effects are to be expected when one crosses the limited pesticide amount per unit area. Even the time-gap between usages are also put into consideration when talking about health adversities due to pesticides. Extensive repetition of chemical exposures are dangerous and can cause itchiness in the nose, eye, and skin. It can also cause specific breathing issues, as well. It is recommended to leave the sprayed area for about 4-5 hours (away from the sunlight and moisture, if possible) after the initial spray, as the chemical transfer to the skin is minimum.

Specific people who must never come into contact with the chemical contents of pesticides include especially kids as well as pregnant women. It is also recommended to spray the pesticides in the night-time for quicker break-down and exposure.

Steps to be safe

Keep the following key points in mind when you are about to spray an area with pesticides if you want to put mosquitoes in control:

  • If there are any children or pregnant women in the household, shift them to a faraway room. Make sure they don’t come anywhere near the sprayed area, as even little chemical exposure to these sensitive people can cause potential diseases. Don’t let them enter the sprayed area for 24 hours for optimum safety.
  • Altogether avoid the sprayed area for a minimum of 2-3 hours for less sensitive people. The longer the period of wait, the lesser the risk of any potential health damage.
  • It is best recommended to conduct aerial spraying at evenings or night-hours as there is little to no sunlight exposure for them to reside.
  • During the mosquito spray inside a room, make sure there no openings from which the pesticides can exit. If there are any air-conditioning systems, circulating vents, or exhausts in the room, make sure they are shut close during and after the spray. All of them can be used after 3-4 hours after the initial spray.
  • While spraying, make sure you are covered and protected with gloves, eye goggles, and full clothing.
  • Any unnecessary item or body part that has come in contact with the pesticide must be washed immediately. After the spray, wash your clothes in a separate laundry session. Rinse off bare skin.
  • If ever you happen to experience any discomfort or itchiness in the skin and the throat, consult a specialist or an experienced doctor for appropriate treatment.

Steps to control mosquitoes 

As mentioned above, pesticides have a tremendous impact on not just mosquitoes, but any other pests like bed bugs, etc. Keep the above steps in mind. Don’t overspray the room and suffocate yourself. Keep the amounts in control and make sure the room incompletely closed. Stay out of the sprayed area for 3-4 hours minimum.

An excellent way of keeping mosquitoes away is to prevent them. Keep your house clean and don’t leave any breeding spots in and around—clean puddles and areas in contact with rainwater after a monsoon shower.


Keep your house clean and free from any breeding environment for mosquitoes to increase. Eliminate the existing mosquitoes by spraying very fewer amounts of pesticides. Keeping the above things into consideration, one can be mindful of the health adversities caused by pesticides and how can it be prevented.
