– PEST CONTROL SERVICES –
Hundreds of ladybirds packed into the corners of a window frame, clusters in the loft, yellow stains on the sills and an odd smell every time you disturb them. Behind almost every indoor ladybird problem is the harlequin ladybird, and once they choose your home for the winter, they tend to come back every year. Wiltshire Pest Services Ltd provides professional ladybird pest control for homes and businesses across Wiltshire and into the borders of Somerset, Dorset and Hampshire. Call us on 07711 259749 or use the form on this page and we’ll clear them and help keep them out.
– LOVED BY HOMEOWNERS & BUSINESSES –
Harlequin ladybirds move indoors to shelter over winter, so the signs usually appear in autumn and again in early spring when they wake up.
Harlequins gather in tight clusters in window frames, ceiling corners, curtain folds and roof voids. A handful can turn into hundreds within a few weeks.
Lofts and roof spaces that catch the sun, especially south or west-facing ones, are favourite spots. You may find large numbers along the eaves, rafters and around the loft hatch.
When disturbed, harlequins release a yellow fluid from their legs. It stains paintwork, curtains and soft furnishings and can be hard to remove.
That same fluid has a musty, bitter smell. In rooms with large clusters, it can linger long after the ladybirds have gone.
If ladybirds suddenly appear on warm days in February or March, it’s usually a winter cluster waking up somewhere hidden in the building.
Harlequins are slightly larger and rounder than most native ladybirds. Their colour varies widely: orange or red with many spots, black with two or four red patches, or even with no spots at all. Most have brown legs and a white mark behind the head shaped like an M or W. They were first recorded in Britain in 2004 and are now common across the country.
The native seven-spot ladybird is red with exactly seven black spots and black legs. Native species rarely gather indoors in large numbers, so a big cluster inside the house is almost always harlequins. If you’re not sure, send us a photo.
Harlequins leave a chemical scent that draws others to the same spot, so a building that hosts one winter cluster often attracts another the following year.
Crushed or disturbed ladybirds leave yellow stains and a lingering smell, which is a real problem in homes, holiday lets and businesses.
Harlequins can give a small nip, and some people react to them with sneezing, itchy eyes or skin irritation. They aren’t dangerous, but they’re unpleasant to live with.
Hoovering up the ones you can see doesn’t reach the clusters hidden in roof voids and wall gaps, and it does nothing to stop more arriving next autumn. Sprays can also leave stains and dead insects in places you can’t reach.
Call us or use the form on this page. Tell us where you’re seeing them and how many: window frames, the loft, a spare room. If you call, we’ll take the details and send you a follow-up form through our booking system, then talk you through your options and what happens next.
We find where the clusters are and how the ladybirds are getting in, checking lofts, roof voids, window frames, eaves and soffits. For roofs and high fascias that are hard to reach, we can use a drone survey. Commercial sites get a full professional survey before any treatment plan is agreed.
We plan the treatment around where the clusters are, the type of property and who uses it, including children and pets. We explain what we’re doing and why, so you know what to expect.
Clearing this year’s cluster is only half the job. Our proofing service seals the gaps around windows, eaves and roof edges, and fly screens can stop them getting in through open windows. We also help remove insect remains and deal with odours so the room is usable again.
After treatment, domestic customers get a follow-up to check everything has been resolved. Because harlequins return to the same buildings each autumn, businesses and larger properties can take a service agreement with seasonal checks.
We price each job once we understand it. The main factors are the size and number of clusters, where they are, how easy the loft and roof are to access, and how much proofing is needed. Get in touch for a clear quote.
Our team has over 30 years of combined experience, including BPCA-certified professionals and a Fellow of the RSPH. Every technician is qualified to at least Level 2.
High-end food manufacturers rely on us to meet BRC and AIB audit standards, where insects getting into buildings isn’t an option. Your home gets the same attention to detail.
If a few ladybirds on the window are just passing through, we’ll tell you. We only recommend treatment when it’s needed.
We arrive in unmarked vehicles and keep the job low-key, which matters to holiday lets and businesses.
Because harlequins come back to the same buildings, we focus on how they’re getting in, not just this year’s cluster.
Check window frames, door frames, eaves and vents in late summer and seal gaps before the ladybirds start looking for winter shelter in September and October.
South and west-facing windows are the most attractive. Fly screens let you open them without letting ladybirds in.
If a few get in, sweep or vacuum them up gently and empty the vacuum straight away. Crushing them causes staining and releases the smell. Our guide to dealing with a harlequin ladybird infestation has more tips.
Harlequin ladybirds gather in warm, sheltered buildings to survive the winter. Once a few settle, their scent attracts many more, which is why numbers can grow so quickly.
No, but they can bite, stain surfaces and cause allergic reactions in some people. Large indoor clusters are a nuisance rather than a danger.
Harlequins are larger and rounder, vary widely in colour and spots, and usually have brown legs and a white M or W mark behind the head. The native seven-spot is red with seven spots and black legs.
They don’t damage the structure, but their yellow fluid stains walls, paintwork and fabrics, and large clusters leave a lingering smell.
Often, yes. Harlequins are drawn back to buildings where others have sheltered before, so sealing entry points is the best way to break the cycle.
Mostly from September to November, when they look for winter shelter. They become active again on warm days in late winter and early spring.
It depends on the size of the infestation, where the clusters are and how much proofing is needed. We give you a clear quote once we understand the problem.
