Signs of scorpions in San Marcos, CA
Scorpions are nocturnal and secretive, so most sightings happen by accident, at night, or when moving something that has sat undisturbed. A UV flashlight is the most reliable way to confirm activity.
How to tell if you have scorpions
- Scorpions glowing under UV light at nightA quick sweep of the yard, patio, and garage floor with a UV flashlight after dark is the clearest way to see how active a property really is.
- Scorpions found in shoes or stored itemsFinding one in a shoe, glove, or towel left outside points to a population close enough to the house to be using it for cover.
- Activity near rock walls or wood pilesScorpions favor cool, dark hiding spots, so rock landscaping, retaining walls, and stacked firewood are the first places to check.
- Sightings after moving outdoor itemsLifting a planter, board, or stack of bricks that has sat in place for a while often reveals a scorpion underneath.
- Increased activity after warm eveningsScorpions come out to hunt more actively on warm nights, so a jump in sightings during a heat spell is a normal seasonal pattern, not a new infestation.
