Keeping scorpions out of the home is easier and more reliable than chasing them once they are inside. Scorpions hide by day and come out at night, and you usually find one where you least expect it: inside a shoe, among clothes, or at a bathroom drain.
This article focuses on prevention: why scorpions enter homes, where they hide inside and around the house, and how to seal entry points and build a barrier that protects your home. For the dangerous scorpion types and sting first aid, see Scorpions: Dangerous Types, Sting First Aid and Control.
Why do scorpions enter the home?
- Food: scorpions eat cockroaches and other insects, so a house with many insects is attractive to them.
- Moisture: they like bathrooms, kitchens and places with water leaks.
- Shelter: clutter, boxes and shoes are ideal hiding places during the day.
- Heat: on summer nights they leave their shelters, move more and enter through any gap they find.
- New construction: homes near open desert, empty plots or building sites see more scorpions because their shelters are disturbed.
Where scorpions hide inside the home
- Shoes, clothes and towels left on the floor.
- Under beds and behind sofas and wardrobes.
- Bathrooms and around drain openings.
- Storerooms, cardboard boxes and old belongings.
- Cracks in walls and around door frames.
- Around air-conditioner pipes and their openings.
Where scorpions hide around the home
- Under stones and bricks, and in wood and firewood piles.
- Among palm fronds and garden waste.
- In cracks in boundary walls and outer walls.
- Around valve boxes and irrigation lines.
- In sand and soil piled against the house wall.
Scorpion entry points
A scorpion's body is flat and it can enter through a gap about as thin as a bank card. The most common entry points are:
- The gap under doors, especially outer doors.
- Drain openings in bathrooms, kitchens and yards.
- Air-conditioner pipe openings and service lines passing through walls.
- Windows without mesh or with torn mesh.
- Wall cracks and gaps between tiles and walls.
Prevention steps inside the home
- Fit a door sweep or rubber strip at the bottom of outer doors so no gap remains.
- Seal cracks around doors, windows and air-conditioner pipes with silicone.
- Cover drain openings with tight covers, especially at night.
- Fit intact mesh on windows and vents.
- Shake out shoes and clothes before wearing them, and keep them off the floor.
- Move beds slightly away from walls, and do not let bedding touch the floor.
- Reduce clutter in storerooms and rooms, and use sealed plastic boxes instead of cardboard.
- Control insects inside the home, because less food makes scorpions look elsewhere.
Tidying the yard and garden
- Remove stones, bricks and wood piles near the house.
- Clear garden waste and palm fronds regularly.
- Trim shrubs and climbers that touch the walls.
- Keep a strip of gravel or paving about one metre wide around the house instead of soil and grass.
- Fix water leaks around the house.
- Use yellow outdoor lighting, because white light attracts the insects scorpions feed on.
A chemical barrier around the home
Once entry points are sealed and the yard is tidy, a chemical barrier completes the protection:
- Spray a band around the outside of the house, roughly one to two metres wide along foundations and walls, with a product that has long residual activity.
- Spray around doors, windows, drains and air-conditioner openings from the outside.
- Use insecticide dust inside cracks and voids that sprays cannot reach.
- Place glue boards in corners and behind doors to see where scorpions move and catch any that get in.
- Repeat the treatment as the label directs, and more often in summer, the peak scorpion season.
Night inspection with UV light
Scorpions glow under ultraviolet (UV) light, which is the easiest way to find them:
- Walk around the house one to two hours after sunset with a UV torch.
- Focus on boundary walls, corners, stone piles and drain openings.
- If you find many scorpions in one spot, treat the hiding place and seal the nearest entry point.
Is there an effective scorpion repellent?
- Smells such as vinegar and lavender do not give consistent results; they may keep a scorpion away from one spot but do not protect the house.
- Ultrasonic devices have no strong evidence of repelling scorpions.
- What actually works: sealed entry points + a tidy yard + a chemical barrier + insect control.
Farms, rest houses and children's rooms
- Farms and rest houses have more scorpions because of stones and waste, so they need regular clearing and a barrier around buildings.
- When camping in the desert, shake out bedding and shoes and keep them off the ground at night.
- In children's rooms, keep the cot away from the wall, check the room before bedtime and keep toys in sealed boxes.

Scorpion prevention FAQs
What attracts scorpions to the home most?
Insects they feed on, such as cockroaches, moisture, and hiding places like clutter and stones close to the house.
Can scorpions come up through drains?
Yes. Drain openings are among the most common scorpion entry points, especially in ground-floor homes, so covering them at night matters.
When are scorpions most active?
In summer and on hot nights. Activity drops in winter, but scorpions do not disappear completely.
Is spraying alone enough?
No. Spraying without sealing entry points and tidying the yard gives only temporary protection; it is best to combine prevention with a chemical barrier.
