Texas yellowjacket colonies usually last into the late fall in Texas, leaving more opportunity for unpleasant interaction with humans and thus giving them a nasty reputation. Avoidance is the best policy in most situations if you don’t want to tackle yellowjacket removal in Dallas on your own. While foraging away from their nests they are seldom aggressive and usually will not sting unless provoked or they feel their nest is being threatened. Resist the urge to “swat” and simply move carefully away. If you want to be more deliberate in removal, what steps should you take?
Tips to Get Rid of Yellowjackets
1. Minimize attractive food sources. When eating outdoors, keep food and beverages covered. Clean spills and leftovers promptly. Make sure trash cans have tight-fitting lids. Whenever possible, trash cans should be located away from eating areas. Be especially careful when drinking from beverage cans which may contain foraging individuals. When they are abundant, keep your thumb over the opening of the can between sips.
2. To help get rid of yellowjackets, spray a dilute solution of ammonia and water (6 oz of ammonia/gallon water) in and around trash cans and on tables. Use household ammonia, not Clorox (bleach).
3. Although only of marginal benefit, set traps for yellowjackets. There are traps available that can catch impressive numbers, however they must be properly baited and positioned around the outer perimeter of the area you wish to protect.
4. If the nest opening can be located (usually underground in a burrow, beneath rocks or landscape timbers, or within a stone wall), carefully apply an aerosol wasp insecticide into the opening. Treatment should be performed late at night after the insects are in the nest and less active. Note the location of the nest during the daytime, so you will remember where to direct your treatment after dark. Do not shine the beam of your flashlight directly into the nest entrance as this may startle the wasps; instead, cast the beam to the side to illuminate the nest indirectly.
As with hornets, yellowjackets are extremely aggressive when the nest is disturbed. You may want to leave Texas yellowjacket removal to the professionals.
