Is Mosquito Fogging Safe for Kids, Pets and Plants?

Fogging machines blowing clouds of smoke through the neighbourhood are a familiar sight during the monsoon. Many people welcome it, and many worry about what it means for children, pets, food and plants. The answer depends on the product, the method and how carefully precautions are followed.

This guide is general information. Follow the provider's instructions and the product label. If anyone has health concerns, speak to a doctor.

The short answer

Fogging uses insecticides, so it is not risk-free. When done by trained professionals with registered products, according to the label, fogging is generally used in homes and communities, but children, pregnant women, older people, people with asthma and respiratory conditions, and pets should stay away during fogging and until the fog has cleared and the area has been ventilated, as advised. Food, utensils, water, toys and pet items should be covered or removed. Fish, birds and some plants can be harmed, so tell the provider and take precautions. Fogging gives short-term relief, so use it with breeding-site control.

Who should take extra care

• Infants and young children.
• Pregnant women.
• Older people.
• People with asthma, allergies or other respiratory problems.
• Pets, including birds, fish, small animals, cats and dogs.

Before fogging

1. Tell the provider about children, pregnant women, health conditions, pets, fish tanks and birds.
2. Ask for the product name and safety information.
3. Cover or remove food, utensils, drinking water, toys and pet bowls.
4. Cover fish tanks and turn off air pumps, as advised, or move them.
5. Take birds and small pets away.
6. Close windows and doors if fogging is outdoors near your home, as directed, and keep children inside or away as advised.

During fogging

• Keep children, pets and vulnerable people away from the area.
• Do not stay in the fog.
• Do not fog near open flames, and keep away from fire hazards, since some products and carriers are flammable.

After fogging

1. Wait for the time advised by the provider before re-entering, and ventilate.
2. Keep children and pets away until the fog has cleared and surfaces are dry.
3. Wash exposed toys, utensils and surfaces.
4. Rinse fruit and vegetables from the garden before eating.

Plants and gardens

• Some fogging chemicals can harm sensitive plants and beneficial insects such as bees.
• Cover or move delicate plants if advised.
• Tell the provider about vegetable gardens and edible plants.

Limits of fogging

• It kills adult mosquitoes in the air for a short time.
• It does not stop breeding. Mosquitoes may return within days.
• Repeated, unnecessary fogging adds exposure without extra benefit.

Safer alternatives and supplements

• Remove breeding sites weekly.
• Treat water with larvicide through professionals.
• Use screens, nets, fans and repellents.

When to see a doctor

If anyone develops breathing difficulty, irritation, headache or nausea after fogging, move to fresh air and seek medical advice.

When to call a professional

Use trained providers and ask about precautions. Avoid unregulated or informal fogging.
