Polistes exclamans, P. fuscatus & others
The wasp that builds umbrella-shaped open-celled nests under your eaves, deck railings, and door frames. Paper wasps are significantly less aggressive than yellow jackets — they will sting if the nest is directly threatened, but don't chase or swarm as readily. Small early-season nests can be safely removed.
Signs of Paper Wasp include physical sightings, droppings or frass, damage to food or materials, and unusual odors. Inspect hidden areas like wall voids, behind appliances, and in storage spaces. A flashlight inspection after dark is often most revealing.
Paper Wasp can pose health risks including bites, allergic reactions, food contamination, and disease transmission. Children, elderly, and pets are especially vulnerable. Consult a pest management professional when an infestation is confirmed.
Light infestations may be manageable with DIY baits, traps, and targeted treatments. Established infestations typically require professional intervention. Misapplied products often scatter pests and worsen the problem long-term.
Timelines vary by infestation size and method. Baits may take 1–4 weeks to work through a colony. Chemical treatments often require 2–3 applications spaced 2–4 weeks apart. Monitor for 30–60 days after treatment to confirm elimination.
Paper Wasp are typically drawn by food sources, standing moisture, warmth, and shelter. Sealing entry points, reducing clutter, fixing leaks, and storing food in airtight containers are the most effective long-term prevention measures.
