Yellowjacket Infestations: Identifying and Controlling These Aggressive Wasps

Yellowjackets are known for their distinctive black and yellow striped bodies, which resemble those of bees. These aggressive wasps are a common problem during the summertime, and their stings can be incredibly painful.

In this article, we will discuss how to identify yellowjackets, their feeding behavior, what attracts them to a location, and ways to remove yellowjacket food sources.

Yellowjacket Description

Yellowjackets are a type of wasp that range in size from half an inch to an inch long. They have a distinct black and yellow striped body, and their antennae are short and stubby.

Yellowjackets have long, thin legs that are designed for grasping onto prey. Unlike bees, yellowjackets have smooth, shiny bodies and a more elongated shape.

They are known for their stingers, which can be used repeatedly to defend themselves or attack other animals or insects.

Yellowjacket Feeding Behavior

Yellowjackets are omnivores and can feed on a variety of food items, including nectar, fruit, and insects. However, they prefer protein sources because they need the amino acids present in proteins to produce eggs.

This means that they often go after other insects such as flies, caterpillars, and spiders. They are also attracted to sugary drinks and fermented fruit.

If they discover a reliable food source, they will return to it frequently, sometimes bringing their entire colony with them.

Yellowjacket Attraction To Protein Sources

If you find yourself dealing with yellowjacket infestations, there’s a good chance your property is harboring a protein source that’s attracting them. Garbage, pet food, and spilled sugary drinks are all common culprits that can attract yellowjackets.

To prevent yellowjackets from entering your home or backyard, it’s important to make sure that all food sources are properly secured. This means ensuring all garbage cans are properly sealed, storing pet food in airtight containers, and cleaning up any spills immediately.

Ways To Remove Yellowjacket Food Sources

Another way to control yellowjacket infestations is by hiring a pest control professional. They can inspect your backyard and identify any potential food sources or nests.

Once the location of the nest is identified, they will typically use a pesticide to destroy it. If the nest is in a location that’s difficult to access, a professional may use a vacuum to remove the wasps before sealing the entrance of the nest to prevent any further entry.


Yellowjacket infestations can be a common and annoying problem, especially during the summer months when the insects are more active. Identifying yellowjackets and understanding their feeding behavior is important to control their numbers.

By removing any potential food sources and seeking professional pest control help, you can ensure that your home and backyard are yellowjacket-free. Yellowjacket Treatment: Preparing for Effective and Safe Wasp Control

Yellowjacket infestations can be a cause of concern, and its important to prepare adequately before treating the problem.

The following information covers preparation for yellowjacket treatment, choosing the right treatment method, protective clothing recommendations, and steps for a successful application.

Choosing the Right Treatment Method

There are various methods to eradicate yellowjackets, and each method has its advantages and disadvantages. The most common methods are baits, sprays, dusts, foams, and traps.

Baits are a good choice when only a few wasps are present. They contain a slow-acting poison that the yellowjacket takes back to the nest, killing the entire colony.

Sprays work best for treating visible nests that are within reach. They come in pressurized cans and should be used from a safe distance.

Spray the nest until it is completely coated, and be prepared to run away quickly to avoid getting stung. Dusts, foams, and aerosols are best for treating hidden or underground nests.

Foams are activated with water and are perfect for hard-to-reach areas like wall voids. Dusts are available in insecticide dust or pyrethrin formulations and kill the wasps when they come in contact with them.

Aerosols have a long-range spray and can be sprayed directly into wall voids or other areas where the yellowjackets are active. Traps work by luring the wasps into the trap with a bait, such as sweetened water.

They are most effective in the early fall when the colony has mostly produced males and queens, which are then trapped, preventing them from mating and reproducing.

Protective Clothing Recommendations

Yellowjacket stings are painful, and some individuals may have an allergic reaction to them. For this reason, its important to wear protective clothing when attempting to treat an infestation.

Long-sleeved shirts, pants, boots, and gloves offer the best protection. Its also a good idea to wear a hat with a veil or netting to protect the neck and face.

Steps for a Successful Treatment

1. Locating the Nest: The first step in treating an infestation is to locate the nest.

Look for wasp activity during daylight hours when yellowjackets are most active. Follow the flight path of the wasps to determine where the nest is located.

2. Identifying Entry and Exit Points: Once youve located the nest, it’s important to identify the entry and exit points.

This will help you target the application of the insecticide and get the best results. 3.

Applying the Treatment: Apply the treatment according to the instructions on the label. If youre using a spray, stand a safe distance away, aim the nozzle of the can at the nest, and spray until the nest is covered with insecticide.

If using dust or foam, apply the product directly into the nest opening, covering the inside of the nest. 4.

Checking the Nest for Activity: After treatment, give the insecticide time to work. It’s important to check the nest for activity after a week or so.

If there is still activity, repeat the treatment. Once the nest is inactive, you can remove it safely.


Controlling yellowjacket infestations can be a daunting task, but with the right preparation and treatment, it can be accomplished. Choose the right treatment method for the situation, wear protective clothing, and follow the steps for a successful treatment.

Keep in mind that yellowjacket infestations can be dangerous, so safety should always be a top priority when attempting to treat it yourself. Yellowjacket Treatment: Home Remedies and Conventional Options

Dealing with a yellowjacket infestation can be a frustrating experience, but there are a variety of treatment options available.

Depending on the severity of the infestation and your personal preferences, you may choose to use home remedies or conventional treatment options. Here, we’ll explore some of the different options available.

Home Remedies for Yellowjacket Treatment

1. Covering the Nest with Bowls:

One home remedy for trapping yellowjackets involves the use of glass bowls.

Simply place an upside-down glass bowl over the nest entrance, trapping the wasps inside. Leave it there for a few days to ensure all the wasps are dead before removing the bowl.

2. Using Dry Ice:

This method involves putting dry ice close to the yellowjacket nest, which causes the carbon dioxide from the dry ice to pool inside the nest.

This leads to the death of most wasps in the nest. 3.

Applying Peppermint Oil:

The strong scent of peppermint oil repels yellowjackets and can keep them away from your property. Mix a few drops of peppermint oil with water in a small spray bottle and spray it on and around your property.

4. Using Protein Bait:

Create your own trap for yellowjackets by placing a piece of meat or fish in a container or bottle with small holes punched in it.

The yellowjackets will be attracted by the smell and fly inside but won’t be able to get out. 5.

Destroying the Nest:

One of the most effective ways to deal with a yellowjacket infestation is to locate and destroy the nest. This can involve spraying the nest with an insecticide, or removing the nest entirely.

6. Hanging an Imitation Nest:

Yellowjackets are territorial and will avoid nesting near other nests.

Hanging an imitation nest near an active nest can trick yellowjackets into thinking the area is already occupied, deterring them from nesting there. 7.

Using a Wet-Dry Vacuum:

This method involves setting up a vacuum nozzle and funnel to collect the yellowjackets and trap them in soapy water.

Conventional Yellowjacket Treatment Options

1. Dusting:

Insecticidal dust treatment is a conventional method of dealing with yellowjacket infestations.

The dust is applied directly to the nest, where it kills the wasps on contact. 2.


Drenching involves spraying the nest and surrounding area with a liquid insecticide. When appling a liquid insecticide, be aware of the risk of the product seeping into water sources.

3. Baiting:

Chemical bait treatments can be effective at drawing yellowjackets away from your property.

The wasps are attracted to the bait, which contains a slow-acting poison that they take back to the nest, killing the colony. 4.


Trap methods work by luring the wasps into a trap with a sweet-smelling bait. The wasps are trapped inside the container and die over time.


Dealing with a yellowjacket infestation can be a challenge, but with the right treatment approach, it is possible to minimize the pain and annoyance caused by their presence. Whether you opt for home remedies or conventional treatment options, make sure to consider the safety precautions needed when handling insecticides and use appropriate protective gear.

Choose the treatment that works best for your situation and remember that if the infestation is severe or you have an allergy, it may be best to consult a professional pest control service. Yellowjacket Treatment and Prevention: Tips to Keep Your Property Wasp-Free
