Mosquitoes are a common household nuisance in Australia, particularly in warm, humid regions like Queensland, the Northern Territory, and coastal areas. These pests thrive in moist environments and require standing water to breed, making humidity control an important factor in reducing their presence indoors.
While insect repellents and sprays are widely used, many Australians wonder whether dehumidifiers can help keep mosquitoes at bay. This guide explores how humidity affects mosquitoes, whether dehumidifiers can reduce their activity, and the best methods for keeping your home mosquito-free.
How humidity affects mosquito activity
Mosquitoes thrive in warm, humid conditions of up to 90% humidity, especially when combined with high temperatures. Without enough moisture, mosquitoes become dehydrated and less active.
High humidity allows mosquitoes to:
- Stay hydrated, as they absorb moisture from the air.
- Find ideal breeding conditions, especially in damp areas.
- Increase their activity such as flying and laying eggs as dry environments can dehydrate and weaken them.
Lowering indoor humidity levels can make the environment less hospitable for mosquitoes, reducing their presence inside homes and workplaces.
Can dehumidifiers get rid of mosquitoes?
Dehumidifiers help by removing excess moisture from the air, creating a less favorable environment for mosquitoes. However, they do not repel or kill mosquitoes directly. Here’s how they can still play a role in mosquito control:
How dehumidifiers help get rid of mosquitoes
✅ Lower humidity levels, making it harder for mosquitoes to survive.
✅ Reduce condensation and damp areas where mosquitoes may rest.
✅ Minimise indoor standing water caused by excess moisture buildup.
✅ Disrupt mosquito breeding by drying out potential egg-laying areas.
✅ Help prevent mould and mildew, which thrive in the same humid conditions that mosquitoes prefer.

Limitations of dehumidifiers against mosquitoes
❌ They do not repel or kill mosquitoes – Unlike insecticides or sprays, dehumidifiers do not eliminate mosquitoes directly.
❌ They only work indoors – Mosquito breeding mainly occurs outdoors in standing water, which dehumidifiers cannot address.
Other ways to control mosquitoes indoors in Australia
Mosquito control is especially important in high-risk areas like Brisbane, Darwin, and Sydney, where mosquito-borne diseases such as Ross River virus and dengue fever are a concern. To complement the effects of a dehumidifier, consider these additional mosquito control methods:
To complement the effects of a dehumidifier, consider these additional mosquito control methods:
- Use mosquito screens – Install mesh screens on windows and doors to prevent entry.
- Eliminate standing water – Fix leaks, empty plant trays, and keep drains unclogged.
- Use mosquito repellents – Apply sprays, essential oils (like citronella), or plug-in mosquito repellents.
- Improve air circulation – Mosquitoes struggle to fly in strong airflow, so using fans can help keep them away.

While dehumidifiers don’t eliminate mosquitoes directly, they play an important role in reducing indoor humidity, making it less ideal for mosquito activity—particularly in humid Australian climates.
For effective mosquito prevention, combine:
✔️ Dehumidification to lower humidity levels.
✔️ Eliminating breeding grounds to disrupt their life cycle.
✔️ Using repellents and barriers to prevent mosquito entry.
