Mosquitoes are a vector for many global diseases. In Ontario they are associated with transmission of West Nile Virus[https://www.publichealthontario.ca/en/DataAndAnalytics/Pages/WNV.aspx]. Low impact development technologies reduce the amount of standing water compared to traditional stormwater ponds as most water is stored in voids within soil and gravel layers. The maximum recommended surface ponding time is 24 hours after a storm event, as this is less than the time required for one mosquito breeding cycle. In some high density urban landscapes, it may be desirable to have a shorter ponding time.

Where designs do include standing water (e.g. in [[Rainwater Harvesting|rainwater harvesting]]), the following practices can reduce mosquito habitat further:
