Stink bugs have spread steadily across Greece over the past decade, turning up in homes, holiday apartments, hotel rooms, and offices — especially in autumn when they push indoors looking for warmth. The video above walks through a proven four-step method; this article expands each step with practical advice tailored to Mediterranean properties. Follow the sequence below and you can clear an infestation without triggering the pungent defensive spray that earns these insects their name.
Why stink bugs are a growing problem in Greece
The brown marmorated stink bug (Halyomorpha halys) arrived in southern Europe in the 2000s and has no native predators to keep populations in check. Warm, dry Greek summers accelerate breeding, so by September colonies are large and actively seeking shelter.
Rental properties and hotels are hit especially hard because frequent guest turnover means doors and windows open constantly, and end-of-season management tasks often get delayed until after the bugs have already moved in.
What not to do — and why it matters
The biggest mistake property owners make is swatting or vacuuming stink bugs without sealing the entry points first. Crushing them releases a sharp, pungent odour (a mix of aldehydes and other compounds) that can linger for days on soft furnishings and is very difficult to neutralise.
A second common error is reaching for broad-spectrum sprays indoors without reading the label. Many aerosol insecticides have no residual effect on stink bugs and only push them deeper into wall cavities, making the problem harder to resolve.
5 steps to get rid of stink bugs
- 1
Inspect and map all entry points
Walk the entire perimeter of the building at dusk when bugs cluster on warm walls. Check where utility pipes, cables, and air-conditioning lines enter the structure. Note gaps around window frames, roof eaves, fascia boards, and any damaged weatherstripping. In older Greek stone houses, pay particular attention to the joins between timber beams and masonry — these gaps are prime entry corridors.
- 2
Seal gaps with long-lasting materials
Use silicone-based caulk for hairline cracks around window and door frames. For larger gaps — particularly around pipe penetrations — use an expanding polyurethane foam. Fit fine-mesh (1 mm or smaller) insect screens on all windows and replace torn or loose door sweeps. In rental properties, completing this step before the autumn season (late August) dramatically reduces the number of bugs that ever get inside.
- 3
Apply a perimeter insecticide treatment
A residual pyrethroid spray (products containing bifenthrin, deltamethrin, or lambda-cyhalothrin are widely available in Greek agrotika shops) applied to the outer walls, window frames, and door thresholds creates a chemical barrier that kills bugs on contact before they enter. Spray on a dry day when no rain is forecast for at least 24 hours, and reapply after heavy rainfall. Always follow label instructions and keep people and pets away from treated surfaces until completely dry.

Remove or trap bugs already indoors
Never crush live bugs. Instead, use one of two safe methods: fill a container with warm soapy water and gently drop bugs in — the soap breaks surface tension and they drown quickly and odourlessly — or use a dedicated light trap (a UV-LED device over a catch tray) placed in a dark room overnight. Empty traps daily into a sealed bag and dispose outdoors. For rooms with heavy infestations, a handheld vacuum with a bag is effective; seal and remove the bag immediately after use to prevent the smell from escaping inside.
- 5
Make the interior less attractive long-term
Stink bugs are drawn to warmth and light. Switching exterior lighting to amber or yellow LED bulbs (which attract fewer insects than white or blue-spectrum lights) reduces the nightly congregation on your walls. Inside, keep blinds partially closed in lit rooms at night during peak season (September to November). Remove any indoor potted plants that are showing pest damage, as these can act as secondary feeding sites that encourage bugs to stay.

FAQ
- Will stink bugs damage my furniture or bite my guests?
- Stink bugs do not bite humans or damage wood, textiles, or upholstery. Their harm is entirely sensory: the defensive smell is unpleasant and hard to remove from soft furnishings. In larger numbers they can also damage fruit and vegetable gardens. The priority is removal and exclusion, not structural repair.
- How do I get rid of the smell after a bug has been crushed?
- Ventilate the room immediately. Wipe the affected surface with a cloth soaked in a 50/50 mix of white vinegar and water, then follow up with a baking-soda paste on porous surfaces. For fabrics, a cold-water wash with an enzyme-based detergent works best. Avoid heat — it sets the odour compounds into fibres.
- Is professional pest control necessary, or can I handle it myself?
- Most infestations of fewer than 20–30 bugs can be resolved with the steps above without a professional visit. If bugs are emerging from inside wall cavities in large numbers over several days, that typically indicates a colony has overwintered inside the structure and a licensed pest-control company should assess whether targeted void treatment is needed.
