Mosquito Management

Neither the City of Arvada nor Jefferson County Public Health have a mosquito control program; however, we do suggest residents take some precautionary measures towards mosquito management. 

  • Drain water where mosquitoes can breed, including flower pot trays, bird baths, wheel barrows, plugged gutters, toys, etc. This can reduce the number of mosquitoes hatched significantly.

  • Install or repair window and door screens to keep mosquitoes out.

Fight the Bite: The 4 Ds of Preventing Mosquitoes

Rain followed by warm weather increases the number of mosquitos. The best way to protect yourself, your family and your community from mosquito bites is to follow the four Ds. 


Even the smallest containers like coffee and soda cans can hold enough water for mosquitoes to lay eggs.  Thoroughly inspect all areas around your home and work for standing water and drain or empty all standing water.


Take extra care to use repellent and protective clothing during evening and early morning (dusk and dawn) or consider avoiding outdoor activities during these times when mosquitoes are most active.


Dress in long sleeves and pants during dusk and dawn or in areas where mosquitoes are active. Wearing light-colored clothing may also help prevent being bitten.


Wear insect repellant containing either DEET, Picariden, or oil of lemon eucalyptus.

  • Follow label instructions
  • Apply repellants to exposed skin and/or clothing.
  • Never use repellants over cuts, wounds or irritated skin
  • If using DEET, choose the concentration that best fits the amount of time spent outside. 25 % DEET lasts up to five hours, 5% lasts 45-90 minutes. Use a concentration of 30% or less for children.
  • DEET should not be used on children less than 6 months of age. Oil of lemon eucalyptus should not be used on children less than 3 years of age.
