Springtails in a Newly Built Home: Sealed-In Moisture Dwellers, Harmless

The small, brown, six-legged, two-antennaed insects in your kitchen and bathroom—slow, easy to catch, antennae sometimes curled—are springtails (Collembola), primitive soil insects.

Why in a New House?

• They lived in the soil/lumber during construction.
• Sealed in as the envelope closed.
• Persist while building materials hold moisture (concrete, drywall, wood).

Facts

• Feed on mold, fungi, bacteria—not food, wood, or people.
• Harmless. No bites, no damage.
• Will decline as the house dries (months to a year).

Action

• Sweep/vacuum when seen.
• Run bathroom fans, dehumidifier.
• No insecticide needed—sprays are messy and ineffective.

This is a normal new-home phenomenon. Not an inspection failure.
