Pesticides and fertilizers applied around homes, residential or commercial landscapes, school sites, and other areas can enter our creeks, rivers, and oceans, degrading water quality. While pesticides and fertilizers can be useful in controlling pests and helping plants grow, their overuse and misuse can harm the environment and human health.
To find out more, see our updated pages on urban pesticides, fertilizers, and water quality. These pages feature plain language definitions of toxicity and water quality and explanations of how pesticides and fertilizers get into our waterways.

You've heard of terms such as green, organic, natural, ecofriendly, and less toxic to describe pest control products and services. But what do these terms really mean?

First, it is important to understand mosquito biology. Mosquitoes are small flies that lay their eggs in, on, or near stagnant water. The larvae, or wigglers that hatch from the eggs live in water and feed on organic debris until they transform into a motile pupa, or tumbler, and finally into the familiar adults. This process, from egg to adult, requires as little as one week when conditions are favorable. Emerging females...
