What It Is
Yellowjackets are social wasps, not bees, in the genera Vespula and Dolichovespula. They are the insect most commonly misidentified as a bee by homeowners and the most commonly encountered stinging insect in late-summer residential situations. Colony sizes peak in late summer and can reach tens of thousands in established nests. Size: roughly 1/2 inch, compact and stocky.
How to Identify
Bright, high-contrast black and yellow banding. Smooth body with no body hair. A pronounced narrow waist. This is the insect most people picture when they say bee but it is a wasp. Yellowjackets are seen at outdoor food and garbage, foraging for protein and sugar, especially in late summer. Honeybees forage at flowers. If an insect is investigating your food or garbage, it is almost certainly a yellowjacket. Nest: most commonly underground in soil cavities. Also in wall voids, crawl spaces, and attic spaces. The nest itself is enclosed gray paper material.
Behavior and Risk
Yellowjackets are highly defensive. They sting without direct provocation if the nest is disturbed, and they respond quickly in numbers. Alarm pheromone from one sting triggers others. They can sting multiple times. Ground nest disturbance during lawn mowing or stepping near the entry is the most common cause of mass yellowjacket stings. Late summer colonies are at maximum size and workers are at peak defensiveness. Venom causes pain and local swelling. Allergic individuals face anaphylaxis risk.
How to Handle
If you discover a ground nest or wall void nest: do not disturb it. Mark the area to prevent accidental approach. Keep people and pets away. Contact a pest control company. If you accidentally disturb a ground nest: move away rapidly in a straight line. Do not swat. Get indoors or into a vehicle immediately.
Yellowjacket vs. honeybee: yellowjackets are bright yellow-black, smooth, and often seen at food; honeybees are amber-brown, fuzzy, and seen at flowers. If it is fuzzy, it is a bee. If it is smooth and bright yellow, it is a yellowjacket.
Frequently Asked Questions
Are yellowjackets bees?
No. Yellowjackets are wasps. They do not produce honey in the quantities that honeybees do, do not build wax comb, and are removed by pest control, not bee relocation.
Why are yellowjackets so aggressive in late summer?
Colony size is at its annual peak and worker populations are at maximum. Workers become more active foragers and more defensive as the colony maximizes before the winter die-off.
What should I do if there is a yellowjacket nest in my lawn?
Do not disturb it. Mark the area to prevent accidental approach. Contact a pest control company for treatment, typically done at night when workers are in the nest.
Does Beecasso remove yellowjackets?
Yellowjackets are wasps, not bees. Contact a licensed pest control company. If you are unsure whether you have yellowjackets or a honeybee colony, send us a photo and we will identify it for free.
Is a yellowjacket the same as a bee?
No. The fastest check: if it is fuzzy and amber-brown, it is a bee. If it is smooth and bright yellow-black, it is a yellowjacket. Yellowjackets are also commonly seen at food and garbage, where honeybees are not.

We live in an apartment complex where beecasso was kindly called to be of service by our apartment management team, to address a cluster of bees that were trying to make their home on our patio. Not only did Beecasso team member, Caleb, come out next day, he was incredibly professional, thorough, and kind during his service. Jerry, another Beecasso team member, also came out the following day and followed the same professional, empathetic, and efficient service that we received the day prior. After the treatment, we had a question about the lingering bees and called the service line that was provided to us on a handout given by Caleb on the first day, explaining more about the process. Steve, the manager / owner, answered and was incredibly knowledgeable, reassuring, and committed to helping the issue resolve. All I can say is that with every interaction, Beecasso was exactly the type of service team that I would hope to address our concerns. They were also extremely sensitive to the alarm presented since we have a bee allergy in our home, and also a tenant next door also has a bee allergy as well and we just wanted the bees gone. So, it was really important to us that no straggler bees entered our house as each service person came and went through our home to the patio. Each member of the team were so cautious and attuned to help keep the inside “bee-free.” Although this is not our property, we are beyond thankful that our management found / contracted this business because they truly were everything we could have hoped during this unsettling process.
We had such a great experience with Beecasso recently. Two technicians came out and they were incredibly professional and kind. They were wonderful with my kids and made sure we felt comfortable throughout the process. They efficiently removed a super large beehive from our garage and did beautiful repair work afterward. The bees were gone quickly, and you'd never know there had been a problem. I highly recommend this company for their expertise and genuine care for their customers!
They came within a day of my calling to relocate my bees. The owner on the phone conveys genuine concern for the plight of bees and doing the best that he can for them. The gentleman who came were friendly and professional.
