How to Get Rid of Yellow Jacket

Yellow Jacket, How to Get Rid of


Yellow Jackets are about 3/8″~5/8″ long and the queens are about 25% longer. Their abdomen is usually banded with yellow and black, that is how they get their name yellow jackets. Some are white and black, and some species are marked with red. When yellow jackets are resting, their wings are folded longitudinally. Yellow jackets are social insects and live in nests or colonies. During the winter, only the inseminated queens hibernate and survive, while all the other yellow jackets die.


Yellow Jackets usually select a subterranean or above ground nesting site. Most of the yellow jackets species are ground nesters. However, it does not mean that they will not establish a nest in and on buildings. They can nest on shrubs, bushes, houses, garages, sheds, etc. and those that nest in the ground are commonly found in areas with bare vegetation or a clear area around an entrance.


When treating the yellow jackets nests, avoid the entrance opening of the hive when you are treating it because it only increases the chance of being stung. During the day, locate the nests and mark the entry points so that you do not forget. All treatments should be done at night when they are all in the nest. Yellow Jackets do not see well at night so the chances of being stung are significantly reduced.

Crack and Crevice/Void Treatment:
Yellow Jacket treatment is generally applied with a liquid spray (LambdaStar 9.7% CSFenvaStar EcoCap), dust (DELTA DUST), and aerosols (  STINGRAY WASP & HORNET SPRAY, PT WASP-FREEZE AEROSOL). They are to be applied to small cracks and crevices in a structure with a bee might enter or build its nest near. For liquid spray application (LambdaStar 9.7% CSFenvaStar EcoCap), you will need to have a pressure sprayer or a gallon sprayer. You will need to apply using the amount that is directed on the label and may need to reapply if needed. You will have to use a low pressure system with a pinpoint or variable patter nozzle to apply the spray mixture to areas such as the side, under gutters, shutters, wooden decks/patios, attics, and any where else that Yellow Jacket nests are found. The dust application is simple. However, when using dust please be cautious especially when children and pets are present. Dust (DELTA DUST) and aerosol formulas ( STINGRAY WASP & HORNET SPRAY, PT WASP-FREEZE AEROSOL) are generally preferred here. If you find a hole on the side outside of your home, you will insert the tip of the duster with an extender (BELLOW BULB DUSTER) containing the dust into the hole and use as directed to holes or channels in damaged wooden member of the structure, to cracks, spaces or bearing joints between the wood members of the structure, or in the holes of the hives. Apply lightly and uniformly to infested area. DO NOT OVER USE DUST. We suggest that you use DELTA DUST because even in moisture, it will not wash out or be blown out. This dust is active for 6 to 8 months. Using the aerosol formula (STINGRAY WASP & HORNET SPRAY, PT WASP-FREEZE AEROSOL), be cautioned because aerosol is a liquid so do not use in electric outings, use only dust. You will just need to attach a thin straw to the nozzle depending on the product, and spray into the hole. Since the aerosol and/or dust will be the outer part of the hole, it will rub off on carpenter bees and it will transmit them inside the tunnel which in turn will cause them to die.

Drenching Treatment:
For this application, we suggest you use a gallon sprayer . Then you will need to mix a liquid formula by following the label directions and then applying the entire volume of the mixed liquid directly to the nest on the ground (LambdaStar 9.7% CSFenvaStar EcoCap). If the bumble bee built there nest under the ground, spray directly into the entrance, if you can not find the entrance, spray the surrounding area. It will take approximately 1-2 gallons of dilution for each nest area. Spray the nest until wet and apply a 4 foot diameter circle around the nest. Applications should be made in the evenings when the bees and wasps are resting. You can also use aerosol formulas ( STINGRAY WASP & HORNET SPRAY, PT WASP-FREEZE AEROSOL). At night, do not shine the light directly into the entrance of the hive and/or nest. Hold the container in straight upside position and stand at least 6-15 ft from the hive and/or nest. Align the opening with the mark on the cap and aim the actuator opening towards the hive and/or nest. Spray the hive and/or nest until thoroughly wet.

Broadcast Treatment:
This treatment is generally used for large turf or other landscape areas and contains directions for specific amounts of the product to be applied as a liquid spray (LambdaStar 9.7% CSFenvaStar EcoCap) to a given area. Broadcast treatments are usually for the entire lawn, in this case when you cannot find the bee nest. Applications should be made in the late evening when insects are at rest. For this treatment, we suggest a 1 gallon sprayer for the application of liquid spray . Following the directions on the label, you would spray the entire lawn with the solution.

    Which of these products will be Ok for use with a pet cat in the area, whch is a garden terrace surrounded by stone walls, earth and sand? I keep the cat in at night.

    Generally pesticides are safe for small children or pets once it has completely dried. A product I recommend for Yellow Jacket treatment would be Tempo WP.
    The mixing rate for yellow jackets would be 4 scoops to a gallon of water. It will provide a fast knock down and a long residual time to continue to kill them over a long period of time. (3-4 months)

    We have what looks like a large amount (about 200) small yellow jackets going into an eaves area on our roof. We can not see the nest as they are going in a small crack area. What treatment would be best to get rid of them? Thanks,
    Anne Bongiovi

    Hi Anne,
    The only thing that we can recommend to you is a residual spray that can be sprayed in that general area. Something like Onslaught Insecticide or Demon WP is recommended. However, if it is too high up or if the infestation is as large as you describe, we recommend that you hire professionals to eradicate the infestation. I apologize that I was not able to better assist you.

    I live in a subdivision, and the yard right next to ine is up for sale and vacant. There is a fairly large hole with yellow jackets flying in and out right next to my side of the yard, but it’s in the vacant yard next door. My dog got stung several times last week, resulting in a $300 vet bill, and I’m wondering if I should try to take care of the nest myself, or call the realtor who is listing the house to have him or the owner take care of it. I also have 2 kids and my husband who are very allergic. Any help would be appreciated. Thanks

    Hi Heidi,

    With yellow jackets, we recommend getting a professional to take care of the infestation unless you are willing to eradicate the infestation yourself. Professionals have fogging tools and will safely remove the infestation. If you would like to treat the infestation yourself, we recommend using Wasp Freeze to kill the flying adults before applying anything to the nest. Wasp Freeze or Stingray Aerosol are both jet aerosol sprays that kill on contact. During the late evenings or early morning, we recommend applying Delta Dust to the nest. This will also kill them on contact but has a residual. It is a dust, so it can be washed away or blown away with wind, so we recommend reapplying it once a week until you are sure you have eradicated the infestation. If you have any further questions or comments, please feel free to contact us again! Good Luck.

    Hi, we have several yellow jackets going in and out of our shutters out front of our house. They go into at least 3 if not all of our shutters. My husband has been using a Wasp and Hornet spray and has killed several flying ones. He sprayed it into the shutters (or tried) at night but we are still seeing some go in and out.
    Of note, my dog ran into a nest in the ground on the trail that runs behind our house and got stung several times. Dont know if those are related or not.
    Should we continue with the spray or do something else? And will it keep them away if we seal off the gaps in the shutters?

    We are trying to avoid hiring a professional, if we can do it on our own as I am sure it will cost a fortune.

    Hi Valerie Reha,
    Might I suggest using a residual insecticide? I wonder if you have tried that yet. By spraying a residual insecticide on the shutters and other surfaces of the isolated areas of infestation, you do not have to carry around a can of wasp freeze everytime you walk outside. Something like Suspend SC or Cy-Kick CS will work for yellow jackets. I hope that helped. If you have more questions, please feel free to contact us again or give us a call at 1-800-788-4142.

    Hi, I have a nest of yellow jackets beneath some plantings right next to my home. I am unable to accurately locate the entrance hole due to the plants. Is there an dry insecticide in powder or crystal form that can be applied to the plantings, and then watered in to penetrate and destroy the nest?

    Hi Doug,

    Unfortunately, we don’t carry any sort of product like that and I’m not so sure if there is a product like that on the market (I may be very wrong, but we don’t carry anything like it) and so I won’t be able to give you an accurate response. However, we know that yellow jackets are fairly easy to get rid of. If your plants are ornamental plants, you can spray certain insecticides on the plants without hurting them. For instance, Suspend SC is labeled for use on ornamentals, which means that you can apply it in isolated areas of infestation around the plants. Due to the residual time, you will only have to apply this as necessary in the beginning part of your treatment plan and then move on to quarterly treatments. I hope that helped. If you have any questions though, please feel free to contact us again via email at or by phone at 1-800-788-4142.

    I have a nest of yellow jackets behind the brick on my patio. A tiny hole under the window. tried spraying W/wasp yellow jackets. Raid. After spraying put some caulk in the hole did not work.I know what to do if they are in ground. Pour gasoline in the hole kills them .No more jackets.

    For yellow jackets try using Tempo 1% Dust. It will definitely give you better results than Raid.
