How to Find Yellow Jacket Nest in Wall

Yellow jackets are aggressive insects that can pose a threat if they build their nests inside your walls. Locating their nest in the wall can be challenging as they can enter through small cracks and crevices. However, with a little patience and careful observation, you can identify their nest and take appropriate measures to remove it. Here are some steps to help you find a yellow jacket nest in the wall:

1. Observe the flight patterns: Watch the yellow jackets as they enter and exit your home. By observing their flight patterns, you can determine the general area where their nest may be located.

2. Listen for buzzing sounds: Yellow jackets make a distinct buzzing sound when they are active. Pay attention to any buzzing sounds coming from inside the walls, as this can indicate the presence of a nest.

3. Look for entry points: Inspect the exterior of your home for possible entry points. Check vents, gaps in the siding, or any cracks that may serve as an entrance for the yellow jackets. Seal these openings to prevent further access.

4. Use a stethoscope: If you suspect the nest is inside the wall, you can use a stethoscope to listen for buzzing or scratching sounds. This can help pinpoint the exact location of the nest.

5. Observe nesting behavior: Yellow jackets often build their nests in hidden, dark areas. Look for signs of yellow jackets clustering around a particular spot, such as a small opening or crack in the wall.

6. Watch for increased activity: As the nest grows, yellow jacket activity will increase. Keep an eye out for an escalation in the number of yellow jackets entering and exiting your home, as well as increased buzzing sounds.

7. Use a thermal camera: A thermal camera can detect the heat signatures of the nest, making it easier to identify its location. This method is particularly useful for larger nests.

8. Seek professional help: If you are unable to locate the nest or if you are dealing with a large infestation, it is best to seek the assistance of a pest control professional. They have the expertise and necessary equipment to safely remove the nest.
