Wasps Identification
How To Identify Wasps
Wasps have slender bodies with narrow waists, smooth skin, and long legs that often hang beneath them during flight. Unlike bees, wasps can sting multiple times because they do not lose their stinger.
Many species build paper-like nests in protected areas around homes, while others create underground colonies. Wasps become increasingly defensive as their colonies grow throughout the summer.

COMMON WASP SPECIES
Not Every Wasp Behaves The Same Way.
Different wasp species build different types of nests and display varying levels of aggression. Identifying the species helps determine the safest treatment approach.
Yellow Jacket
Yellow jackets are highly aggressive social wasps that commonly build underground or wall-void nests and aggressively defend their colonies.
Size: 10–16 mm
Paper Wasp
Paper wasps build umbrella-shaped paper nests beneath roof overhangs, decks, and porch ceilings. They are generally less aggressive unless disturbed.
Size: 16–20 mm

Bald-Faced Hornet
Despite the name, bald-faced hornets are a type of wasp known for building large enclosed paper nests in trees and shrubs.

WHAT WASPS NEED
Your Property Provides Ideal Nesting Conditions.
Wasps look for safe, sheltered areas where they can build nests close to food and water sources.
Food Sources
Adult wasps feed on nectar and sugary foods, while they hunt insects to feed developing larvae.
Water
Bird baths, puddles, irrigation systems, and other standing water help sustain growing colonies.
Protected Spaces
Quiet, undisturbed areas allow colonies to expand throughout the warm months.
Shelter
Roof eaves, sheds, attics, trees, fences, and outdoor structures provide excellent nesting locations.
