Scorpions

Scorpions at Home: What Attracts Them and How to Prevent Them

Finding a scorpion in your shoe or behind a piece of furniture is an unpleasant surprise for anyone. In Costa Rica it's more common than you'd think, especially in homes with a yard, firewood, or rooms that don't get much use. The good news: a few concrete tips can help you reduce hiding spots and entry points and feel more at ease. Scorpions look for darkness, moisture, and insects to eat; take those away and they have less reason to stick around. The WHO notes that if you get stung, you should seek medical care.

In brief
  • Fewer hiding spots means fewer scorpions: keep boxes, firewood, and debris away from the house.
  • Shake out shoes and clothes before putting them on; check towels and sheets if you sleep on or near the floor.
  • Fewer insects (cockroaches, crickets) means less food for scorpions.
  • Stung? Get medical care right away; if you can, bring a photo of the animal (without touching it).
Important

If you're stung by a scorpion, seek medical care. In Costa Rica it helps to identify the species; if you can, bring a photo of the animal (don't handle it).

Prevention tips that actually work

  • Yard and surroundings: don't stack boxes, debris, firewood, or stones against the house. Keep the grass trimmed and avoid dense weeds against walls. Scorpions love those corners.
  • Shoes and clothes: always shake out shoes, boots, and clothing before putting them on, especially if they were on the floor or in a room that doesn't get much use. Check towels and bedding if you sleep on a mat or close to the floor.
  • Cracks and doors: seal cracks in walls, floors, and door frames; add weatherstripping to doors and check that vents and grilles don't have gaps. At night, scorpions can get in through the smallest openings.
  • Less "food" for them: scorpions feed on insects. Controlling cockroaches and crickets makes your home less appealing. Fewer bugs means less reason for a scorpion to stay.
  • Garage and storage room: keep them tidy; avoid piles of cardboard, fabric, or boxes on the floor. If you store things, use shelving and check on it now and then.
