Understanding Longmont's Mosquito Season
The active period for mosquitoes in Longmont typically begins in late April or early May and extends until the first hard freeze in mid-October 1. Peak activity, and the highest risk for West Nile Virus (WNV), occurs from June through September 2. Mosquitoes are most active from dusk until dawn, and their populations thrive during warm, humid weather, especially where standing water is present 3 4. Understanding this seasonal cycle is key to planning effective prevention and treatment strategies for your property.
Public Mosquito Control: A Focus on Public Health
The primary goal of the City of Longmont's mosquito program is not general nuisance reduction but the prevention of West Nile Virus, a serious public health concern 5 6. The city contracts with a specialized firm, Vector Disease Control International (VDCI), to run an Integrated Pest Management (IPM) program that prioritizes environmentally responsible methods 6 7.
How the Public Program Works:
- Larvicide is Primary: The most effective and targeted strategy is applying larvicide to public water sources. This eliminates mosquitoes in their aquatic larval stage before they can hatch and become flying adults, minimizing the need for widespread spraying 6 8.
- Adulticide is Targeted: Spraying for adult mosquitoes (adulticiding or fogging) is not done on a regular schedule. It is only triggered when specific public health thresholds are met: when trap counts of Culex mosquitoes (the primary WNV carriers) exceed 150 and WNV-positive mosquitoes are found in Boulder, Larimer, or Weld counties 5 9.
- Weekly Monitoring: VDCI begins weekly trapping and monitoring in June to track mosquito populations and virus activity 6.
- No Direct Cost: This public health service is funded by taxes, so there is no direct charge to residents for these city-wide treatments 5.
- Resident Options: Homeowners can choose to be notified before a spray event occurs in their area or can request that the spray machine be turned off as it passes their property by contacting VDCI directly 6.
This program is essential for community-wide disease prevention but is not designed to eliminate all biting mosquitoes from private yards.
Private Mosquito Management for Your Property
For homeowners seeking relief from nuisance mosquitoes to enjoy patios, gardens, and lawns, numerous local pest control companies offer yard treatment services. These services focus on creating a protective barrier around your home and treating your property's specific mosquito breeding sites 10 11.
Common Private Treatment Methods
Barrier Sprays: This is the most common service offered. A technician applies a residual insecticide to the perimeter of your yard, focusing on foliage, under decks, and other areas where mosquitoes rest. These treatments are designed to last several weeks before a reapplication is needed 10 12.
All-Natural or Organic Options: For those preferring plant-based solutions, many companies offer treatments derived from botanical oils like rosemary, citronella, or peppermint. These are generally considered safer for pets and beneficial insects, though they may require more frequent application and often come at a slightly higher price point 13.
Source Reduction and Larviciding: A comprehensive service often includes inspecting your property for standing water-in plant saucers, clogged gutters, old tires, or bird baths-and treating these potential breeding sites with a larvicide to prevent new generations from hatching 10.
Combination Services: Mosquito control is frequently bundled with tick and flea treatments or general perimeter pest control, providing broader protection for your outdoor space 14.
Service Frequency and Structure
Private mosquito abatement is typically offered on a scheduled maintenance plan throughout the active season.
- Treatment Cycles: Most barrier sprays remain effective for 21 to 30 days, necessitating monthly or sometimes bi-weekly visits during peak season 10.
- Seasonal Packages: Many providers offer a seasonal contract that covers the entire mosquito season, often including 8 to 9 scheduled visits from April/May through September/October 15.

Understanding Costs for Private Mosquito Control
Pricing for private yard spraying varies based on your property size, the frequency of service, and the type of treatment (standard vs. natural). It's important to get quotes from several local providers 16 17.
- Per-Visit Cost (within a seasonal plan): A standard barrier spray application typically ranges from $59 to $150 per treatment. More comprehensive plans that include larviciding or natural formulas can range from $69 to over $200 per visit 10 18 19.
- One-Time Treatment: For a special event like a backyard wedding or party, a single application usually costs between $75 and $300 16.
- Annual Seasonal Contract: Paying for the full season upfront often provides a discount. Total seasonal costs in Longmont commonly range from $600 to $1,200 or more, depending on the factors mentioned above 15 17.
Choosing the Right Mosquito Control Strategy for You
Your best approach depends on your primary goals:
- For Public Health Support: Rely on and support the city's tax-funded IPM program. You can stay informed about WNV risk and spray notifications through the City of Longmont's website.
- For Personal Comfort and Nuisance Reduction: Engage a private pest management company. Look for licensed professionals who offer a free inspection and quote, explain their treatment methods (including any pet-safe drying times), and provide clear contract terms for seasonal work.
- For an Integrated Approach: Do your part by eliminating standing water on your property weekly. Then, supplement with private treatments if nuisance levels remain high, knowing the public program is working in the background on WNV control.
DIY Prevention: Your First Line of Defense
Regardless of whether you hire a professional, every Longmont homeowner should practice source reduction:
- Weekly Water Dumping: Empty and scrub items that hold water-bird baths, planters, toys, and pet bowls-at least once a week.
- Maintain Gutters and Drains: Keep gutters clean and ensure downspouts drain properly.
- Cover or Treat Water Storage: Use tight-fitting lids on rain barrels or treat them with mosquito dunks (a type of larvicide).
- Landscape Management: Keep grass trimmed and shrubs pruned to reduce cool, damp resting areas for adult mosquitoes.
