Common Habitat of Hornets:

Hornets are large, social wasps that build paper-like nests in sheltered locations. Outdoors, they commonly nest in tree branches, shrubs, eaves, attics, wall voids, and under rooflines. Some species may also build nests in hollow logs, fence posts, or deck structures. Hornets forage widely for nectar and other insects, especially during warmer months, and become more active as colonies mature through late summer and early fall.

Risks & Potential Damage:

Hornets pose a notable risk to people and pets due to their painful, potent stings and defensive behavior when their nests are disturbed. Unlike many other insects, hornets can project venom toward perceived threats, and if that venom contacts the eyes, it may cause intense irritation and, in rare cases, temporary vision impairment. Individuals with venom allergies are at particular risk for severe reactions. Because hornets aggressively defend their nests, professional intervention is recommended whenever nests are located near living spaces, entryways, play areas, or high-traffic outdoor areas.

Signs of Hornets:

Common signs of hornet activity include:

• Visible nests attached to eaves, rooflines, attics, trees, or shrubs.

• Frequent sightings of large wasps flying in and out of the nest entrance.

• Hornets foraging around sweet foods, trash cans, and sugary drinks.

• Increased aerial activity near outdoor structures during warm weather.

Because hornets reuse and expand their nests over time, seeing repeated activity near the same location often indicates an established colony.

Methods of Hornets’ Prevention:

Preventing hornet infestations focuses on reducing attractants and securing potential nesting sites:

• Seal cracks and gaps around eaves, soffits, wall voids, and rooflines.

• Repair damaged screens and install screening on attic and foundation vents.

• Keep lids on outdoor trash cans and clean food spills promptly.

• Minimize the presence of sugary foods and beverages during outdoor gatherings.

• Trim vegetation back from the home and remove old wood piles, debris, or unused structures that could serve as nesting platforms.

Early-season inspections and proactive exterior pest control treatments help reduce the likelihood of hornets establishing nests near your home.
