Bitten in Springdale?

Volume II, Issue 20 · May 19, 2026Printed on page 9

An invasive mosquito has moved into your neighborhood (Specifically St. George, Santa Clara, Washington, Hurricane, & Springdale). It appears it is here to stay, as its eggs can survive the mild winters to hatch at the first sign of water and warm weather. The Aedes aegypti, an urban dwelling container mosquito, loves to hang out in yards and neighborhoods - close to people.

Be proactive to prevent this mosquito in your Spring cleaning.

“Fight the Bite” Checklist:

Eliminate Standing Water Sources by:

  • Removing Clutter
  • Ensuring that all containers have holes to drain or are tipped
  • Checking for sprinkler fed sources
  • Turning over rain fed sources
  • Checking boats and covers
  • Adjusting watering amounts and fixing leaks
  • Tightly covering rain barrels

Allow Site Inspections of: (Call to schedule)

  • Ponds
  • Ornamental Water Features – Especially non-functioning water features
  • French drains

Aedes Aegypti

  • They are usually found in containers in residential areas and bite any time of day.
  • They mainly bite humans, usually around areas with thin skin, like ankles and wrists
  • They can carry diseases that aren’t native to Utah, but they have not been known to carry any diseases in Washington County.

Characteristics & Behaviors

  • The mosquito is black with white patches and banding.
  • They stay relatively close to where they hatch out, but they can fly as far as a block away (in a lifetime).
  • They lay eggs on the sides of containers, and they will hatch out when water is reintroduced, and emerge as adults in as little as 4-5 days.
My goodness, Harold!…. Now there goes one big mosquito!
