Pests in the Urban Landscape

Summer is in full swing and while it's been quite hot in many parts of California, it's been very cool in others.

Are you noticing an abundance of cobwebs outside, on plants, fences, homes, or outdoor furniture? While many people fear spiders or dislike their cobwebs, most spiders are beneficial to have around even in the home! Spiders are predators of many insect pests and rarely cause harm to people.

Acetic acid, also known as vinegar, is used in products for weed control. Many people choose it because it is natural. However, acetic acid can damage skin and eyes, especially at concentrations commonly found in weed killers.

Exotic and invasive pests threaten California's natural environments, agricultural production, structures, landscapes and gardens. Exotic pests are organisms introduced into an area beyond their natural range and become pests in the new environment.

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.
