This index features various insects, arachnids, and animals commonly considered pests, whose common names begin with the letter U. Due to limited common pest names beginning with U, we focus on general categories.
A detailed list and link to more information on them is at bottom of the page
General Pests (U)
- Uniola Moths (Regional): Moth larvae that feed on certain grasses and sedges in specific regions, sometimes becoming a turf or ornamental pest.
- Unknown Pests: A general page dedicated to identifying unlisted or newly encountered pests based on damage type (e.g., unusual tunnels, holes, or droppings).
Wildlife Pests (U)
- Urban Wildlife: A category encompassing various animals (Opossums, Raccoons, Skunks) that become pests when they adapt to and infest urban environments.
Quick Tip: When dealing with Urban Wildlife, remember that local ordinances often prohibit trapping or relocation without a professional license. Exclusion is usually the best approach.
