Ladybugs 101
Ladybugs, also known as lady beetles or ladybird beetles, are found worldwide, with about 475 species living in Canada and the United States. Most species are actually beneficial, feeding on aphids, mealybugs, and other plant-damaging insects in gardens. The trouble starts in fall, when ladybugs look for a warm, protected place to spend the winter and sometimes pick the gaps and cracks in a home instead of a tree or rock pile.
How to Identify Ladybugs
| Colour | Size | Legs | Antennae | Shape | Region |
|---|---|---|---|---|---|
| Red, orange, yellow, brown, or shiny black, often with dark spots | 1/31–3/8″ (0.8–10 mm) | 6 | Yes | Oval to nearly round | Found throughout Canada |
Ladybugs are small, round-to-oval beetles, easy to recognize by their domed shell and spotted markings, though colour and spot count vary widely by species. The multicoloured Asian lady beetle, one of the most common indoors, is usually slightly larger with a small white marking just behind its head.
Signs You Have a Ladybug Problem
- Large clusters of ladybugs gathering on sun-facing, south- or west-facing exterior walls in fall
- Ladybugs appearing indoors near windows, light fixtures, or attic spaces from late fall through spring
- Dead ladybugs collecting on windowsills or inside light fixtures
- A yellow, foul-smelling stain on walls, curtains, or furniture, released when a ladybug is disturbed
- Noticeably larger numbers than the odd one or two you’d expect outdoors in the garden
Protecting Your Home from a Ladybug Infestation
- Seal cracks and gaps around windows, doors, siding, and utility pipes with a quality silicone or silicone-latex caulk
- Check and seal gaps behind chimneys and underneath wood fascia boards
- Repair or replace damaged window and door screens
- Caulk before fall; ladybugs start looking for overwintering spots as temperatures drop
- If a few have already gotten inside, a vacuum is a quick, mess-free way to remove them
- For a recurring cluster, a licensed technician can treat and seal entry points before the next season
Ladybug Health & Property Risks
Allergens
While most species pose no real threat to people, the multicoloured Asian lady beetle, one of the most common overwintering species, can trigger asthma symptoms and allergic reactions in some people.
Staining
When disturbed, ladybugs release a yellow, foul-smelling defensive fluid that can stain walls, curtains, and furniture
Nuisance at Scale
Unlike most household pests, ladybugs overwinter in large clusters, so a single gap can let in dozens or hundreds at once.
Our Ladybug Removal Process
Step 1. Consultation and Inspection
A licensed technician inspects your property to find entry points and any active overwintering clusters, indoors or out.
Step 2. Full-Site Inspection Report
You'll get a clear summary of what we found: entry points, cluster locations, and which species is involved.
Step 3. Custom Pest Control Action Plan
We build a plan around sealing the entry points in use and treating any active clusters already inside.
Step 4. Putting Your Plan Into Action
We remove existing ladybugs and seal the gaps they used to get in, so new clusters can't follow the same path.
Step 5. Guidance on Staying Pest-Free
We confirm activity has stopped and provide you with a list of steps you can take to prevent re-infestation.

Frequently Asked Ladybug Pest Control Questions
How do I permanently get rid of ladybugs?
Exclusion provides the longest-lasting results. Remove indoor ladybugs with a vacuum, then seal gaps around windows, doors, siding, vents, utility openings, and rooflines. Because ladybugs often enter buildings to overwinter, professional exterior treatment before fall can help prevent large groups from getting inside.
How many ladybugs is considered an infestation?
There is no official number that defines a ladybug infestation. Finding one or two indoors is usually normal. Repeated sightings, clusters around windows and light fixtures, or dozens to hundreds emerging from wall voids often indicate an overwintering infestation. The insects commonly involved are multicoloured Asian lady beetles, which gather inside protected spaces during colder months.
What pests do ladybugs get rid of?
Ladybugs are beneficial outdoor predators that feed on aphids, scale insects, mealybugs, mites, whiteflies, and some insect eggs. Their diet varies by species and life stage. Although they can reduce certain garden pests, ladybugs do not reliably eliminate infestations and should not be introduced into a home as a pest-control method.
Are ladybugs harmful or dangerous?
Most ladybug species are harmless and even beneficial in the garden. The main exception is the multicoloured Asian lady beetle, one of the most common species found indoors, which can trigger allergic reactions or aggravate asthma in some people. Beyond that, the bigger issue is usually the sheer number that can gather at once, not any real health threat.
Why are there so many ladybugs in my house?
Ladybugs look for warm, protected spots to spend the winter, and homes with gaps around windows, siding, or fascia boards are an easy target. Once a few find a good spot, they release a scent that attracts more, which is why an entry point can bring in dozens or hundreds rather than just one or two.
What's the difference between a ladybug and an Asian lady beetle?
They look similar: both are round, spotted beetles, but the multicoloured Asian lady beetle tends to be slightly larger, has a small white marking behind its head, and is the species most likely to invade homes in large numbers. Native ladybug species are less prone to clustering indoors.
How much does ladybug removal cost?
Cost depends on how many entry points need to be sealed and the size of the cluster involved. A single vacuum-sized problem costs less to resolve than a recurring seasonal invasion. We provide a free, no-obligation estimate after an inspection so you know the cost upfront.
Do you guarantee your ladybug removal service?
Yes. Every job is backed by the GreenLeaf 100% Satisfaction Guarantee. If activity returns after treatment, we’ll come back and address it at no additional cost.
