Local Risk and How West Nile Virus Spreads

Central Connecticut’s mix of suburban neighborhoods, wooded properties, wetlands, rivers, storm drains, and shaded yards can create mosquito habitat during the warmer months. Connecticut’s mosquito trapping and testing program operates from June through October, and state officials warned in 2026 that West Nile virus had been detected in mosquitoes across Connecticut communities.

West Nile virus spreads when mosquitoes feed on infected birds and later bite people or animals. Birds and mosquitoes maintain the cycle in nature, while humans, dogs, cats, and horses can become infected after mosquito bites. Everyday contact with an infected person or pet is not the typical route of transmission.

In Central Connecticut, mosquitoes can breed in containers, gutters, birdbaths, rain barrels, stormwater areas, pool covers, plant saucers, and low spots where water remains. Even small amounts of standing water can support mosquitoes, especially during warm weather.

West Nile Virus Symptoms, Health Effects, and Treatment

Most West Nile virus infections in people do not cause symptoms. When symptoms appear, they can include fever, headache, body aches, joint pain, vomiting, diarrhea, or rash. Severe illness is less common but can involve the central nervous system, causing meningitis, encephalitis, confusion, tremors, muscle weakness, paralysis, coma, or death. Older adults and people with certain chronic medical conditions are at higher risk for severe disease.

There is no licensed vaccine or specific medicine for West Nile virus disease in people. Mild cases are generally treated with rest, fluids, and symptom management under medical guidance. Severe cases may require hospitalization, IV fluids, respiratory support, pain control, and treatment for complications.

Dogs and cats can be infected through mosquito bites but rarely become seriously ill. Horses are more likely to experience serious West Nile virus disease, and owners should ask a veterinarian about vaccination and prevention. Sudden weakness, tremors, unsteady movement, fever, or unusual behavior in any pet should prompt veterinary attention.

For Central Connecticut residents, mosquito control around the home and bite prevention remain the most practical ways to lower West Nile virus risk.

Frequently Asked Questions

01. What other insects will this affect?

We use a control product so other insects present when and where we spray may be impacted.

However, our formula was specifically engineered for mosquitoes so it won’t repel any other insects as it does mosquitoes.

02. Will your product work after storms?

Yes, we have specifically engineered our formula to outlast storms. With a special polymer layer that provides weather resistance, our formula will remain effective.

03. Is there any environment you cannot treat?

Yes, there are some areas we won’t spray to avoid the surrounding environments. Pools, natural water sources, vegetable gardens, and artificial water sources complete the list.

Because water could easily spread the insecticides, we never directly apply our product to it. However, the rest of the property can still be sprayed and it will drastically reduce the population of mosquitoes.

04. Does this product work on all mosquitoes and ticks ?

Yes, we target aspects of mosquitoes and ticks that don’t change from species to species.

The killing and repelling aspects of our product will work on any species of mosquitoes and ticks .

05. What about my children and pets?

Pets and children should be inside during each application. However, they can re-enter the property once the product has dried, roughly 10-15 minutes. At that point, there are no restrictions until the next application.

06. When can I start to see the effects?

Every yard is different but you should notice a dramatic reduction within 24-48 hours of the initial spray.

With each subsequent treatment, the results continue to improve, allowing you to enjoy time outside without being chased in by swarms of mosquitoes.

07. Why do we see more mosquitoes after it has rained?

Mosquitoes are more abundant after it rains because standing water is where they breed.

Adult, female mosquitoes will lay their eggs in water. Once fully submerged, the countdown begins and the eggs can hatch in as little as a few days.
