Short answer: Scorpion sealing is worth it if you find scorpions inside more than once or twice a season, live near open desert, or have small kids or pets. It costs about $500 to $1,500 once, compared with years of monthly spraying that never closes the gaps.
When sealing pays off
- You find scorpions indoors more than a couple of times a year
- Your home backs onto open desert, a wash or a preserve
- You have young children, older relatives or pets at home
- You've already paid for spraying and still see them inside
- Your home is older, with worn door seals and cracked caulk
When it probably isn't worth it
If you see one scorpion a year, outdoors, a door sweep and a tube of caulk may be all you need. Sealing also won't solve a heavy infestation by itself. If scorpions are already living in your walls or attic, you need treatment first and sealing second.
The math
Most local companies quote about $500 to $1,500 to seal an average home. Monthly or quarterly pest service commonly runs about $50 to $75 a visit, or roughly $400 to $900 a year. Spraying kills scorpions that cross it. Sealing keeps more of them from getting inside in the first place, and good work lasts years with a yearly check.
Ask any company you call whether its sealing is guaranteed, for how long, and whether it covers a free re-check.
What you're actually paying for
Most of the cost is labor: a technician working around the whole house, finding gaps you can't see and closing them one by one. Typical work covers door sweeps and weatherstripping, the weep screed at the base of stucco walls, gaps around pipes and A/C lines, and fine screen on attic and roof vents. See the full list.
Common questions
How long does scorpion sealing last?
Good materials last years. Caulk shrinks and door sweeps wear, so most companies suggest a yearly check.
Does sealing replace pest control?
Not completely. Most homes do best with sealing plus outdoor treatment, especially near open desert.
