Three Rivers Mosquito and Vector Control

Three Rivers Mosquito and Vector Control At TRMVC, we specialize in mosquitoes and other pests that pose potential health risks to our communities. We specialize and are experts in mosquito control.

Three Rivers Mosquito and Vector Control is more than a pest control company that offers mosquito control services. TRMVC is a Central Oregon based business and provides services ranging from feasibility studies and reports for the establishment of vector control programs to evaluations and recommendations for existing programs. We provide training, support and materials for in-house programs as w

ell as providing tailored, full-service control programs. Our Integrated Pest Management (IPM) programs provide you one-stop, full-service management that maximizes your control over mosquitoes and other flying nuisances. Our professional staff develops and tailors programs based on your specific habitats, environmental sensitivities, and budget. Because TRMVC offers the widest variety of application methods, and utilizes the most innovative technologies to assess and monitor each program, we can achieve the right balance of efficacy with environmental responsibility. Plus we offer the industry's fastest scheduling and response time. No other company can service your needs better. TRMVC uses nationally accepted methods to control mosquito populations, including surveillance, source reduction, and the application of EPA-approved larvicides and adulticides for enhanced quality of life in any municipality. TRMVC bases its programs on sound science; routine inspections of treatment areas coupled with collections from surveillance traps enable us to determine the presence of West Nile Virus or other mosquito borne diseases, which mosquito species are present, their approximate population density, type of breeding habitats, and locations. TRMVC employs an IPM approach to scientifically and systematically design customized control programs for each municipality. Every program we design incorporates a combination of computer models, GIS mapping, weather monitoring, and least toxic and most effective biological and chemical controls. TRMVC combines this data with timely reporting to facilitate informed program decisions and critical public education assistance. Three Rivers Mosquito and Vector Control and the American Mosquito Control Association advocates management of mosquito populations when and where necessary by means of integrated programs designed to benefit or to have minimal adverse effects on people, wildlife, and the environment. This integrated pest management (IPM) policy recognizes that mosquito populations cannot always be eliminated but often must be suppressed to tolerable levels for the well-being of humans, domestic animals, and wild life and that selection of scientifically sound suppression methods must be based on consideration of what is ecologically and economically in the long-term best interest of mankind. The following principles are advocated:

•Mosquito control measures should be undertaken only when there is adequate justification based upon surveillance data.
•IPM programs should be tailored to the needs and requirements of the local situation. The combination of methods for mosquito control should be chosen after careful consideration of the efficacy, ecological effects, and costs versus benefits of the various options, including public education, legal action, natural and biological control, elimination of breeding sources, and insecticide applications.
•Mosquito breeding sources, whether natural or created by human activity should be altered in such a manner as to cause the least undesirable impact on the environment.
•Insecticides and application methods should be used in the most efficient and least hazardous manner, in accordance with all applicable laws and regulations and available scientific data. The registered label requirements for insecticide should be followed. When choices are available among effective insecticides, those offering the least hazard to non-target organisms should be used. Insecticides should be chosen and used in a manner that will minimize the development of resistance in the mosquito population.
•Personnel involved in IPM programs should be properly trained and supervised, and certified in accordance with relevant laws and regulation, and should keep current with improvements in management techniques through continuing education and/or training programs. All methods and materials used by TRMVC are based on these principles outlined by the American Mosquito Control Association. The result? Municipalities have everything they need for mosquito control success. Our full service surveillance and control programs have proven tremendously successful at municipal, county, and state levels worldwide.

🦟 Happy World Mosquito Day! 🌎

Today, August 20, we recognize World Mosquito Day—an opportunity to raise awareness about mosquitoes, the diseases they can transmit, and the importance of effective mosquito and vector management.

Mosquito control is more than reducing a nuisance. Through surveillance, science-based control, public education, and community participation, mosquito control professionals work every day to help protect public health and improve quality of life.

This World Mosquito Day, remember: small insects can have a big impact—and prevention matters.
🦟 Eliminate standing water around your property
💧 Tip and toss containers that collect water
🧴 Use an EPA-registered insect repellent when appropriate
🏡 Support mosquito surveillance and control efforts in your community

🦟 Vector control is public health in action.
Every mosquito we prevent today helps reduce the risk of diseases tomorrow. Through surveillance, larval control, and targeted treatments, we're protecting our neighborhoods while minimizing impacts on the environment.

Healthy communities start with proactive prevention. If mosquitoes are becoming a problem in your area, let us know—we're here to help.

The mosquitoes have not been very bad this season in many of our areas... but I've heard the new hatch is a very large and loud species.

Hantavirus Awareness: Prevention Starts with Rodent Control

Recent news stories about Hantavirus can sound alarming, but the risk to the general public remains low — and prevention is very effective when proper vector control measures are followed.

Hantavirus is primarily spread through exposure to infected rodent droppings, urine, or nesting materials — especially in enclosed or undisturbed areas.

Simple Prevention Tips:
✅ Seal openings where rodents can enter homes, garages, sheds, and crawlspaces
✅ Store food and pet food in sealed containers
✅ Remove clutter and rodent harborage around structures
✅ Avoid sweeping dry rodent droppings — disinfect first with a bleach solution
✅ Use gloves and proper protection when cleaning contaminated areas
✅ Contact licensed pest professionals if rodent activity is found

At the end of the day, good sanitation, exclusion, and proactive rodent control dramatically reduce risk.

Stay informed — not alarmed. Prevention works.

“Your Pet = Tick Uber 🐶🚕” - Day 4
Pets can carry ticks straight into your home.

👉 You stayed on the trail… your dog did not.

And once ticks hitch a ride, they don’t just stop at pets—they’ll look for their next meal (you).

“Meet the Local Culprits”-Day 3
In Oregon and the Pacific Northwest, common human-biting ticks include:

Western black-legged tick (Ixodes pacificus)
American dog tick
Rocky Mountain wood tick
Pacific Coast tick ()

👉 The western black-legged tick is the main one responsible for spreading Lyme disease here. ()

Lyme Disease is the disease most commonly known for the bullseye rash.

So yes—ticks are absolutely a local issue.

🌿 “Where Are Ticks Hanging Out (Now Including the NW)?” - Day 2
Ticks don’t jump or fly—they “quest” on grass and shrubs waiting for a host (PestWorld).

👉 Think of them as tiny, patient hitchhikers.

Here’s the concern: ticks are expanding their range into new areas—including the Pacific Northwest—because of warmer temperatures and changing environments. ()

That means places that didn’t used to worry about ticks… now do.
