Boxelder bugs are a common nuisance, especially around homes and buildings near boxelder, ash, and maple trees. These insects often appear in large numbers during hot, dry summers, and they can be a frustrating problem for homeowners. However, there are natural ways to get rid of them without resorting to harmful chemicals.
One effective method to deter boxelder bugs is by washing them off the sides of your home with water. This works best during cooler temperatures when the bugs are less likely to fly away. Another preventative measure can be removing boxelder trees from your property, as these insects primarily feed on such trees.
Using natural remedies not only helps protect your home environment but also keeps the larger ecosystem’s balance in check. By exploring these eco-friendly techniques, you can enjoy a boxelder bug-free space while reducing your ecological impact.
Understanding Boxelder Bugs
Biology and Behavior
Boxelder bugs are part of the “true bugs” family, which includes stink bugs and cicadas. These insects have piercing and sucking mouthparts, and they release a bad odor when crushed. They mainly feed on the sap of female boxelder trees, but can also attack ash and maple trees, as well as raspberry and strawberry plants1. Nymphs are smaller than adults and have distinct red markings2.

Features:
- Piercing and sucking mouthparts
- Bad odor when crushed
-
Characteristics:
- Mainly feed on female boxelder trees
- Can attack other trees and plants
Seasonal Activity
Boxelder bugs are most active during warm seasons like spring and summer3. They tend to overwinter in buildings, and with the approach of fall, they gather in large numbers on the south side of trees and structures4.
| Season | Activity Level |
|---|---|
| Spring | High |
| Summer | High |
| Fall | Congregating |
| Winter | Overwintering |
In summary, understanding the biology and behavior of boxelder bugs, as well as their seasonal activity, is crucial to effectively get rid of them naturally.
Natural Ways to Remove Boxelder Bugs
Vacuuming
- Easy and quick method
- Safe for pets
Vacuuming is a simple and effective method to remove boxelder bugs. Use a vacuum with a hose attachment to suck up the bugs in infested areas. Dispose of the vacuum bag outdoors to prevent the bugs from returning indoors.
Soap Spray
- Non-toxic solution
- Apply on affected areas
A soap and water spray is a safe and environmentally-friendly option to eliminate boxelder bugs. Mix a few drops of dish soap with water in a spray bottle. Apply the solution directly onto the bugs or affected surfaces, making sure not to harm any plants in the process.
Diatomaceous Earth
- Non-toxic insecticide
- Wear protective gear
Diatomaceous earth (DE) is an effective non-toxic insecticide that can be used against boxelder bugs. Sprinkle DE in areas where the bugs are present, like windowsills and doorways. Make sure to wear gloves, safety glasses, and a dust mask when handling DE to protect yourself from any irritation.
Homemade Boxelder Trap
- DIY solution
- Requires simple materials
Creating a homemade boxelder trap is an inexpensive way to catch these pests. Here’s an example:
Items needed:
- A plastic container with a lid
- A small dish, like a disposable aluminum tray
- A hole punch
Directions:
- Fill the aluminum tray with soapy water.
- Place it inside the plastic container.
- Punch several holes in the container lid, just big enough for the boxelder bugs to enter.
- Seal the container with the lid and place it in areas where the bugs are commonly found.
The bugs will be attracted to the trap, crawl through the holes, and ultimately drown in the soapy water. CrossAxisAlignment
Comparison Table
| Method | Pros | Cons |
|---|---|---|
| Vacuuming | Quick, easy, pet-safe | Need to dispose of vacuum bag outdoors |
| Soap Spray | Non-toxic, environmentally-friendly | Need to reapply, may harm plants |
| Diatomaceous Earth | Non-toxic insecticide, effective | Requires protective gear when handling |
| Homemade Boxelder Trap | Inexpensive, DIY solution | May require regular cleaning and maintenance |
Preventing Boxelder Bug Infestations
Exclusion Methods
- Seal entry points: Close all gaps and openings around doors, windows, vents, roof, and cracks with caulk.
- Install door sweeps and window screens: Place tight-fitting door sweeps on exterior doors and fine mesh screens on windows.
- Cover soffit vents: Use fine mesh screens on soffit vents to prevent bugs from entering.
An example of effective exclusion methods includes installing door sweeps on exterior doors, which helps in preventing boxelder bugs from entering your home. Comparing door sweeps to window screens, both serve the purpose of keeping bugs out, but door sweeps are specifically designed for doors while window screens cover windows.
Tree Maintenance
- Remove seed-bearing boxelder trees: Boxelder bugs primarily feed on seed-bearing boxelder trees, ash trees, and maple trees. Remove or reduce these trees in your yard.
- Regular pruning: Trim branches to reduce the resting and hiding spots for boxelder bugs.
- Keep gardens clean: Clean fallen leaves and debris from your yard, as they can serve as a breeding ground for these insects.
Pros of removing seed-bearing trees:
- Reduces boxelder bug food sources
- Decreases potential infestations
Cons of removing seed-bearing trees:
- Loss of tree benefits, such as shade and aesthetics
Garden Care
- Use a garden hose: Dislodge boxelder bugs from plants by spraying them with a strong jet of water.
- Pest control: Consider using natural pest control solutions, such as diatomaceous earth or neem oil, to deter boxelder bugs in gardens.
- Monitor temperatures: Boxelder bugs thrive in hot temperatures, which makes taking precautions during warm months crucial.
Taking good care of your garden is essential in preventing boxelder bug infestations. Keep in mind that diligent tree maintenance and garden care can significantly reduce boxelder bug populations and protect your home from possible infestations.
Safe and Effective Disposal
Properly Handling Pests
Vacuuming can be a quick method to capture boxelder bugs. Empty the vacuum’s dust bag immediately to prevent their escape1. Sealing vents and openings can help keep these nuisance insects out of your home2. Remember, boxelder bugs are harmless and don’t bite or sting. They are a nuisance insect, not a threat to your health.
Avoiding Stains and Injuries
When dealing with boxelder bugs, be cautious not to crush them. Their “juices” can cause stains on fabrics3. Sweep them outside or use a vacuum for easy cleanup4. Dermestid beetles, a similar nuisance insect, can also be handled in the same way.
Comparison Table
| Method | Pros | Cons |
|---|---|---|
| Vacuuming | Quick and easy way to capture bugs | Must empty dust bag immediately |
| Sealing Vents | Keeps bugs out of your home | May require extra maintenance |
| Sweeping | Avoids staining fabrics and easy cleanup | More time-consuming than vacuuming |
Boxelder Bug Features:
- Harmless insects
- Don’t bite or sting
- Can cause stains if crushed
- Known as nuisance insects
- Found around boxelder, maple, and ash trees
Recommended Precautions:
- Seal vents and openings
- Avoid crushing bugs when handling
- Vacuum or sweep them up for disposal
- Actively manage tree populations
Additional Tips and Considerations
Potential Harm to Humans and Pets
Although boxelder bugs are not poisonous, their excrement can stain fabrics, making them unwelcome indoor visitors. In addition, some pets, like dogs, may experience drooling if they come into contact with the bugs. To safeguard humans and pets from potential harm, consider using natural remedies when dealing with boxelder bug infestations.
- Liquid dish soap: A mixture of water and liquid dish soap can help reduce their numbers. Spray it directly on the bugs and egg clusters.
- Vinegar: A vinegar solution can be used to clean the areas where the bugs have been spotted.
Monitor Boxelder Bug Activity
It’s important to monitor boxelder bug activity throughout the year, particularly during late spring and early summer, when eggs hatch and immature bugs emerge. Keep an eye out for the following signs:
- Black, half-inch long adult bugs
- Swarms or clusters of bugs on the sunny side of your home
- Overwintering sites, like cracks and crevices in your home’s exterior
To reduce boxelder bug infestations and avoid the need for hazardous pest control treatments, take the following preventive measures:
- Seal any openings and gaps greater than 1/16th of an inch around your home.
- Use screens on vents and windows to keep them out.
- Remove any boxelder trees within a several-mile radius from your property.
In the event of an infestation, consider these natural methods before resorting to residual insecticides or calling pest control companies:
- Use a vacuum to remove bugs or dispose of them by hand.
- Deploy boiling water or borax to kill emerging nymphs and eggs.
By following these tips and being vigilant about boxelder bug activity, you can effectively protect your home and pets from these pesky insects without causing harm to the environment.

Letter 1 – Boxelder Bugs
the Box Elder Bug
(Name Withheld by Request) here, a US citizen in Alberta Canada, (should you cite me, just refer to me as SW in Alberta). Re: the Box Elder Bug. When I lived in NW Indiana, our house covered on the southern (sunny) outer wall before later when the house was invaded by them. We had them all through the winter months. They lived in the heating ducts. They "spotted" our drapes. I tried a local hardware store (where they sold pest sprays). They had a big, thick book on what to do to rid this or that bug, but on the Box Elder Bug, it said, cut down the box elder tree. We didn’t have any near my house so I tried Venus fly traps. They were so slow closing on them, I basically had to catch and force feed them. I’m glad I moved away from them. BUT, when I got to this part of Alberta (in the prairies) they call the same bug a Maple Bug. I know the Maple Leaf is on the Canadian flag, but I see very few Maple trees here. I think the Cottonwood tree is most prevalent.

Bigger red bugs?
Hi……..
I live in Kansas and was just going to plant a planter in my yard. Upon pulling up an old plant from last summer, I unearthed thousands of little red bugs. At first I thought they were "baby lady bugs" but on further inspection….they have no spots and are a brighter, deeper red. It appears that the adults are about 1/4 " long and the babies are 1/8". I felt as though I had unearthed an ant den……..that’s how they scattered. Also, they have black heads and fine black legs ( hardly visible) Any ideas what they are….or if they are harmful? The planter is connected to the house. Should I be concerned? Do I need to exterminate before replanting? Thanks in advance for your help!
Sheri
Hi Sheri,
I wish you had a photo. They might be Box Elder Bugs. Here is an image of an aggregation. They are difficult to erradicate.
Thank you for your response. After further investigation……..you are correct they are boxedler bugs. I guess it was just a bunch of babies…..because I saw no adults…………until I checked back later. Boxelder bugs are common around here. I’m not too concerned. Anyway, thanks again!

Letter 3 – Boxelder Bugs
And we have been innundated with questions wanting them identified. Seems no matter how many photos of Boxelder Bugs we post, no one ever bothers to scroll down the page.
Letter 4 – Boxelder Bugs
These showed up in my yard last week—I’ve never seen them around before (I live in St. Louis, MO) I have them in what appear to all stages from babies to adults, only the adults seem to fly, and they seem to eat other bugs—dead ones—but I don’t know what else. I don’t know if they are harmful or not. Can you help? I’ve done quite a few web searches, and I must be putting in the wrong search parameters, because I keep getting ladybugs. These are NOT ladybugs!
Thanks–
Carol in MO
Hi Carol,
You should be able to find plenty of information online now that you know you have Boxelder Bugs. They form huge aggregations of both adults and wingless nymphs and feed on boxelder and maple trees. Get rid of them with a mild soapy water.
Letter 5 – Boxelder Bugs
Hi there.
I’ve got these guys all over my siding, and occasionally they make their way into the house. I have no idea what they are, but I’d like to know if they’re going to do any damage to the house or bite anyone. My house is in St. Catharines, Ontario, near Niagara Falls. Any assistance that you could provide would be greatly appreciated.
Thanks!
Michael Hodge
Hi Michael,
These are not beetles, but Boxelder Bugs. They seek shelter inside homes to hibernate. They get very numerous, forming huge aggregations. We currently have an advertiser on our site that claims to be able to erradicate them.
Letter 6 – Boxelder Bugs
Hello,
I live in Southern Ontario and these insects are congregating on the sun warmed side of my home. This is the first time I have encountered these insects in the three years I have lived here. I have googled them but can’t locate any information to identify them or see if they are harmful or beneficial. Any assistance would be appreciated.

Letter 7 – Boxelder Bugs
hi, i have never seen this bug until about 5 years ago. i live in western pennsylvania. when i see these bugs there is not just one but many. the first time i noticed them was when there were so many covering the tire of my daughter’s car that the wheel looked red in color. the immature ones are brighter red and the older and bigger they get, the darker the red becomes and the black markings appear. right now they are crawling up the big tree in my yard and are in my flower bed. do they eat plants and will they destroy them? thanks for the input!
Marsha

Letter 8 – Boxelder Bugs
Hi!
I was trying to identify a bug. They’re dark green with orange markings, and they are all over the exterior of my house. Are they potentially damaging? Should I be afraid? Very, very afraid? I’ve attached a jpg of a mass of them; if you could let me know what you know, I’d be grateful. All best,
Nikki Bess
Hi, again. I think that the bugs in the picture I sent you are eastern boxelder bugs. They’re a little freaky, though: any suggestions for thinning their numbers? Thanks again,
Nikki Bess
Hi Nikki,
Glad you properly identified your Boxelder Bugs. We have heard that spraying them with soapy water does the trick.
Letter 9 – Boxelder Bugs
