The plan that works
- Seal the structure. Pest-proofing is by far the most effective way to reduce scorpion contact. Start with the exclusion checklist.2
- Remove harborage and food. Clear wood, stone, and debris from around the house and cut back the insect prey that draws scorpions. See the yard page.12
- Hunt at night with UV. Repeated blacklight collections genuinely reduce local numbers; the University of Arizona notes several collections over a summer can greatly decrease a local population.3
- Reduce attractant lighting. Bright exterior lights draw the flying insects scorpions eat, so consider changing or relocating them.4
- Use chemicals only as a limited add-on. If used, keep applications outdoors and follow the label exactly.4
What to realistically expect
Eliminating the food supply helps but will not, by itself, clear scorpions from around a home, so no single step is a cure.2 Sticky monitoring traps are useful on two fronts: they catch scorpions and they reveal where the animals are entering so you can target the sealing.4 If a problem persists, it is reasonable to bring in a professional who specializes in pest-proofing, which is covered on the DIY versus professional page.2
