Their large communities can cause real structural damage. Yellow Jacket colonies reach huge sizes, numbering tens of thousands. If you see Yellow Jackets crawling on any structure on your property, you have a problem best dealt with by professionals.

How to Deal with a Yellow Jacket Nest

Get Rid of Yellow Jackets Long Island | NYC | WestchesterKilling Yellow Jackets begins with assessing the size of your infestation and getting a good idea of the damage they may have caused. If the hive has broken through to the interior of your structure, safety precautions must be taken before treatment measures can begin. Treatment is often done at night when the insects have come in from foraging and are settled in for the night.

If you are planning any outdoor activities, it makes sense to have a professional exterminator conduct an inspection to ensure you don’t have active colonies around your deck or in your structure to prevent problems. Be sure to keep food covered with plastic so that the scent of it doesn’t attract the Yellow Jackets. Wear white or tan clothing and avoid perfumes and strong scents.
