BOULDER -- Mosquito pools collected from traps near Longmont and Boulder tested positive for West Nile on July 14, 2013.

Days after five mosquito pools collected from traps in areas near Longmont and Boulder tested positive for West Nile, residents were given notice on Wednesday that areas around both cities will be saturated at some point in the next 24 hours with a spray designed to eliminate the virus.

Spraying takes place just as sunset approaches.

Health officials want to avoid what happened 10 years ago when West Nile virus killed 63 people in Colorado.

Practice the four "Ds"

  1. Use DEET to keep the mosquitoes away; experts say it's the strongest, safest repellent
  2. DRESS in long sleeves and pants when outside
  3. Avoid going outside between DUSK and DAWN
  4. DRAIN any standing water around your house
