Pest control for new homes in Washington County

A new home does not mean a pest-free home. Here is what draws pests to new construction in Southern Utah.

Published September 24, 2026 by Purple Crown Pest Control, a family-owned pest and weed control company in St. George, Utah.

Why new homes get pests

Washington City grew from 8,186 people in 2000 to 27,993 in 2020, and Ivins and Santa Clara have grown too. Many new neighborhoods are built on former desert, next to open ground where desert pests already live. Construction also disturbs the soil and brings irrigation in close to the foundation.

What to look for in a new home

  • Small gaps around pipes, wires, vents, garage doors and door frames
  • Fresh landscaping with drip lines and sprinklers close to the walls
  • Leftover materials such as lumber, pavers and rock stacked near the house
  • Bare, disturbed ground that grows weeds quickly

Pests new homeowners ask about

Ants and earwigs around irrigated landscaping, spiders and scorpions on lots that border open desert, and weeds on new yards. Read about pest control in Washington and pest control in Ivins.

Steps to take in the first year

  1. Check and seal gaps inside the garage and around utility openings.
  2. Keep a clear strip along the foundation and move stacked materials away.
  3. Adjust sprinklers so they do not soak the walls.
  4. Control weeds early, before they seed. See weed control.
  5. Schedule a first treatment if you see pests. See residential pest control.
