Florida has multiple hornet and wasp species. Identification matters because aggression levels and nest types differ. Here is the field guide.

Florida wasps and hornets

Bald-faced hornet

Black with white markings on face. 3/4 inch. Large football-shaped paper nests in trees and under eaves. Highly aggressive.

European hornet

Largest US hornet — 1 to 1.5 inches. Brown and yellow. Common in north Florida. Aggressive when nest disturbed.

Cicada killer wasp

Large 1.5 inch wasp. Yellow and black. Burrows in ground. Looks intimidating but rarely stings humans.

Yellow jackets

1/2 inch yellow and black. Form ground nests with thousands of individuals. Most-aggressive Florida wasp.

Paper wasps

Reddish-brown to dark. Open umbrella nests under eaves. Less aggressive than yellow jackets.

Mud daubers

Slender, often metallic blue. Mud tube nests. NOT aggressive. Beneficial.

Treatment by species

Species DIY? Approach
Bald-faced hornet Caution Long-distance spray at dusk; pro for large nests
European hornet No Hire professional
Yellow jacket No (large nests) Hire professional
Paper wasp Yes Long-distance spray at dusk
Mud dauber Yes (rarely needed) Knock down vacant nests
Cicada killer Optional Generally leave alone

Verdict

For paper wasps, DIY removal at dusk is safe. For bald-faced hornets, yellow jackets, or European hornets, hire a professional. Mud daubers and cicada killers are largely beneficial — leave alone.

Reminder: Always read product labels and follow safety instructions.
