Mosquitoes transmit Eastern Equine Encephalitis to humans.

Several times this season, Mosquito Squad of Central New Hampshire has cautioned you about mosquito borne diseases. Though we all know they exist, sometimes it is easy to go through life as if they don’t, simply because most of us have never been directly affected by them. But this week, Eastern Equine Encephalitis (EEE) strikes close to home, and this time, the disease has not been identified in mosquitoes or horses but rather one of our neighbors. On Friday, the Concord Monitor reported that a Conway resident has been diagnosed with EEE.


Eastern Equine Encephalitis is a serious disease that can affect birds, horses, and humans. It is serious, and there is no treatment other than palliative care while the disease runs its course. There is also no vaccine for humans. EEE is transmitted to birds, horses, and humans though the bite of an infected mosquito. It will not pass from birds or horses to humans, and horses can’t get it from bird or other horses. Mosquitoes are the culprit here. Early human symptoms include many flu-like symptoms: chills, fever, joint pain, muscle pain, and feeling “out of sorts”. Encephalitic infections in humans are the most severe manifestation of the disease. They include: headache, irritability, restlessness, drowsiness, anorexia, vomiting, diarrhea, cyanosis, convulsions, and coma. Typically, an EEE infection will require hospitalization for recovery.


It's more important than ever to to control the mosquito population on your property.

It’s more important than ever to to control the mosquito population on your property.

Be sure that you and your family avoid Eastern Equine Encephalitis this season since it is in our local mosquito population. The very best protection from the virus is to avoid being bitten by the mosquitoes that may carry it. EEE is transmitted by several different species of mosquitoes, so the best defense is to control all mosquitoes. On your property, be sure that you are eliminating any areas of standing water – even if it is just a little water. Mosquitoes can use as little as a teaspoon for a breeding ground. Check the screens on your windows and doors. As temperatures cool, you will probably be using the AC unit less, so be sure mosquitoes can’t find their way into your home. When you venture outdoors, use a mosquito repellent, especially during the morning and evening hours when more mosquitoes are active. But do remember that certain species are active during all hours of the day. Long sleeved shirts and long pants can also make it more difficult for mosquitoes to bite you.


Finally, be sure to maximize your mosquito control by calling Mosquito Squad of Southern New Hampshire. Our mosquito treatments will effectively eliminate up to 90% of the mosquitoes on your property. They are long lasting, up to 21 days even when it rains. We will even set up a treatment schedule, so you don’t have to worry about mosquitoes for the rest of the season. EEE is serious. Be sure that you and your family are protected. Contact Mosquito Squad of Southern New Hampshire today to get the best mosquito control available.

How to Protect Your Southern New Hampshire Horses (and Yourself) from Eastern Equine Encephalitis

Protect your horses from Easter Equine Encephalitis

Protect your horses from Easter Equine Encephalitis

Eastern Equine Encephalitis (EEE) made its way into New Hampshire last week. According to The Eagle Tribune, the State Health Department has found the virus in a batch of mosquitoes in Londonderry (Source). Now that infected mosquitoes have been identified in our area, it is important for horse owners to take precautionary steps that help reduce their horses’ risk of contracting the disease. Though no infected horses have been identified in New Hampshire to date, simple prevention of the disease is best because most horses that contract EEE do not survive.


Symptoms of EEE in horses include erratic behavior, head pressing, unsteadiness, and a loss of coordination. Any horse showing these symptoms should be examined by a veterinarian immediately. While it will not help a horse that is already infected, an equine vaccination exists for Eastern Equine Encephalitis. Fortunately, this vaccine can help prevent horses from getting the disease in the first place. If you own a horse, please discuss the vaccine with your veterinarian. While some owners perform routine vaccinations for their own horses, experts within the Entomology Department at Rutgers University advise against this for this vaccine. The EEE vaccine must be administered according to a specific protocol in order to be effective, and if that protocol is not followed, the horse may not be as protected though the owner thinks it is. (Source).

In addition to the vaccine, horse owners can help reduce risk by controlling the mosquito population on their property and around their stables. EEE is spread to horses through the bite of a mosquito. The disease is not communicable between horses, and horses cannot pass the disease to humans. Like horses, humans become infected by being bitten by an infected mosquito. Unfortunately, an infected horse indicates that the disease is present in the local mosquito population, and there is no way of knowing which mosquitoes are infected without testing. As you can see, the best way to control the disease is to control the mosquitoes that spread it.


In addition to eliminating stagnant water that can easily accumulate in many areas around a stable, owners should treat their property for mosquitoes to have the most effective control. Here at Mosquito Squad of Southern New Hampshire, we are mosquito elimination experts. Our barrier sprays and misting systems can reduce your mosquito population by up to 90%. This means there are far fewer mosquitoes present that could bite your horse or a family member. Protect those you love, both four-legged and two-legged, from EEE by calling us today to talk about your options. You’ll be one step closer to managing the mosquitoes on your property.

A Mosquito is a Mosquito is a Mosquito

The Asian Tiger mosquito can be easily identified by the white and black stripes on its legs and abdomen.

The Asian Tiger mosquito can be easily identified by the white and black stripes on its legs and abdomen.

Right? Well, not really. While it’s true that all mosquito bites hurt, make us miserable, and have the potential of spreading diseases, mosquitoes themselves are actually quite different from one another if we look at them closely. Here in Southern New Hampshire, our environment actually contains 47 different species of mosquitoes, each with unique characteristics. But out of these 47, only a few are responsible for the spreading West Nile virus and Eastern Equine Encephalitis (EEE). The two biggest culprits are the Asian Tiger Mosquito (Aedes albopictus) and the Cattail Mosquito (Coquillettidia perturbans).

The Asian Tiger mosquito is a relatively recent arrival in the United States. Originally a native of tropical climates, it came to our shores in used tires that were imported from the tropics. These mosquitoes are particularly troublesome because they carry West Nile virus and, unlike many others, are active during daylight hours. Asian Tiger mosquitoes are easily identified by black and white stripes in their legs and abdomen.

While all mosquitoes love water, the Cattail mosquito is especially fond of it. In their larval form, these mosquitoes attach themselves to the roots of water plants. They are able to breath underwater, making them impossible to eliminate with larvicides (since larvicides drown mosquito eggs).  These mosquitoes are prone to transmitting EEE and can travel up to a mile at a time. They are brown or tan with darker brown stripes on their legs and abdomen.

No matter what mosquitoes are most prevalent on your property, they all have the following in common:

  • They need water to breed
  • Only the female can bite
  • Their wings beat 300 to 600 times per second
  • They can fly about 1 to 1.5 miles per hour
  • They can smell humans from 60 feet away

A unique case of comorbid insect-borne illness in Hillsborough County, NH has residents taking heed to the dangers of mosquito and tick borne illness

Dread Skeeter for Mosquito Squad

Mosquito Squad of Southern New Hampshire aims to keep residents informed about the risk of mosquito and tick-borne illness in the granite state.

This season will undoubtedly go down in Southern New Hampshire history as the most unusual in comparison to previous years when it comes to mosquito and tick-borne illness. A prime example of the unusual incidence of vector-borne illness reported in our region is making headlines where a  NH man has been reported to have tested positive for two insect-borne illnesses at the same time. The man has tested positive for both The Jamestown Canyon virus, which is transmitted by infected mosquitoes, and the Powassan virus, which is carried by ticks. Both illnesses have never been reported in New Hampshire. Not only is the discovery of these illnesses a first for our area, one is a tick-borne illness and one is a mosquito-borne illness. The presence of two insect-borne illnesses is what is referred to as a “comorbid” illness. Though reports of comorbid insect-borne illness is more likely to occur when a  patient is diagnosed with a tick-borne comorbid illness such as Lyme Disease and Babesiosis since both of these illnesses are carried by the same vector, being the deer tick. It is very unusual to be diagnosed with both a mosquito-borne illness and a tick-borne illness at the same time, as is the case with this man in Hillsborough County, NH. The discovery is causing concern among New Hampshire residents and proves that mosquito and tick related illness is evolving in our region and it is important to take measures to keep yourself protected to reduce your risk of infection from these tiny terrors.

Mosquito and tick together

This pair is making headlines all over New Hampshire as a rare combination of virus caused by both strikes one NH man at the same time.

This report comes at a time when mosquito and tick-borne illness activity is already gaining media attention all across the country.  Just this summer,  two newly discovered tick-borne illnesses have risen to the surface, Heartland Virus and a new illness not yet named attributed to the bacteria Borrelia miyamotoi which are making the rounds in the Northeastern U.S. These two tick-borne illnesses come in addition to a season where we are seeing positive test results earlier than usual in vector-borne illnesses we are already familiar with. Last week, the first reported case of Eastern Equine Encephalitis was confirmed in Belchertown, MA when a horse tested positive for the mosquito-borne disease and elevated the threat level for the disease to critical level in Belchertown.

We are beginning to hear and read stories of these type of occurrences all over the country but none have been quite as unique in nature as the report of the man with a double insect-borne illness right here in New Hampshire. According to WMUR 9 News of New Hampshire, the Jamestown Canyon virus have been around the United States for a while, and the Powassan virus has been found in Maine and Vermont, so the New Hampshire case is not a surprise. The Granite State resident most likely contracted Powassan Virus from the bite of an infected deer tick. Powassan Virus is rare with fewer than 60 reported cases within North America since the late 1950’s.  In regards to the presence of the Jamestown Canyon Virus, or JCV, this virus normally maintains a relationship between mosquitoes and deer, but somehow this Hillsborough County man contracted the virus. The symptoms that led to the discovery of this rare combination of comorbid vector-borne illnesses closely resemble those that are reported in patients with West Nile Virus, which can closely mimic those of the flu. Symptoms readily seen is West Nile are fever headache, body aches and fatigue.

What is Powassan Virus and Jamestown Canyon Virus?

Powassan virus, (POWV) is a rare tick-borne virus in North America. POWV infects the central nervous system and can cause encephalitis and meningitis. Historically, confirmed cases occurred mainly in the northeastern United States. Since 2008, confirmed cases in Minnesota and Wisconsin have increased. The CDC has also reported a fatal case of POWV encephalitis in Minnesota. POWV infection is caused by an arbovirus (similar to the mosquito-borne West Nile virus) but it is transmitted to humans by the bite of an infected tick instead of a mosquito bite. The virus is named for Powassan, Ontario where it was first discovered.

Mosquitoes are responsible for Jamestown Canyon Virus.

Jamestown Canyon Virus is a mosquito-borne pathogen that circulates widely in North America, primarily between deer and mosquitoes, according to Public health director for the New Hampshire Department of Health and Human Services, Dr. Jose Montero, most reported human illnesses, while rare, have been mild, but “moderate-to-severe central nervous system involvement has been reported.” Symptoms of Jamestown Canyon Virus also closely mimic the flu-like symptoms associated with WNV too.

Fortunately, the Hillsborough County man who was diagnosed with this unusual cocktail of mosquito and tick borne illness is expected to make a full recovery. Though this story ends on a good note, Mosquito Squad of Southern New Hampshire urges residents to take heed to the warning this story sends in regards to the risks associated with the presence of mosquitoes and ticks in your backyard. Now is the time to reduce your exposure to mosquitoes and ticks in order to reduce the risk of infection. Mosquito and tick illness is becoming more and more prevalent all over the country. If residents do not exercise safe mosquito and tick practices when venturing outdoors, including your own backyard, it becomes a question of when you or a member of your family will become infected with a vector-borne illness rather than if.

West Nile Virus in New Hamphire- the whole story.

Summer fun mosquito free

Summer fun should be mosquito free!

As a child, I can recall long summer days of carefree outdoor fun that spilled over into the evening hours. Getting bitten by a mosquito was always part of the equation, and so were the whelps and discomfort that followed. Not so very long ago mosquito-borne illness wasn’t a concern our parents worried much about on those fun summer evenings. The only concern of seasonal mosquitoes was the chance of infection from scratching the itchy bites too much. Things have drastically changed in a short period of time when it comes to the way we view mosquitoes.

Fast forward to the present and the many mosquito-borne illnesses we have to consider each time we venture outdoors into an unprotected area and you will realize the impetus of exercising mosquito smart practices.  One of the most prevalent causes for concern is the risk of West Nile Virus. West Nile Virus is a mosquito-borne disease that can cause a mild fever to encephalitis (swelling of the brain) or meningitis (swelling of the membranes surrounding the brain and spinal cord) in humans and other mammals. The West Nile Virus cycle is maintained in nature between mosquitoes and birds, the latter serving as reservoir hosts. The mosquito becomes infected by biting a bird that carries the virus. An infected mosquito can also spread the virus to healthy birds as well. Overwintering adult mosquitoes can harbor the virus and thereby serve as one way of sustaining the disease year to year.

Last year the CDC reported a total of 5,674 cases of WNV disease in people, including 286 deaths.

West Nile was first detected in North America in 1999 in New York City.  Prior to 1999, the illness had only been found in Africa, Eastern Europe, and West Asia. When the outbreak in 1999 took place researchers initially thought it might be St. Louis Encephalitis. During the same time researchers were observing human cases, they also noted an increase in avian mortality including wild crows and exotic birds at The Bronx Zoo. This occurrence was a call to alarm, because St. Louis Encephalitis has never shown a trend in avian mortality.  Other pathogenic arboviruses were investigated as the cause of this unusual phenomenon but, subsequent DNA sequencing of human and avian viral isolates indicated that they were closely related to West Nile (WN) Virus, not previously isolated in the Western Hemisphere. This event marked the beginning of things to come in terms of WNV infection. In 2012, all 48 contiguous states, the District of Columbia, and Puerto Rico reported WNV infections in people, birds, or mosquitoes. According to the New Hampshire Department of Health and Human Services Division of Public Health Services nationally, there has been a dramatic increase in West Nile Virus activity since 2002, including infections reported in New Hampshire.

Mosquito eggs

Reducing the risk of contracting West Nile begins with eliminating areas where mosquitoes breed and lay their eggs.

In our region, human infections of mosquito-borne illnesses such as West Nile Virus and Eastern Equine Encephalitis are as commonplace in the news during the summer months as the prediction of a summer thunderstorm. It can sometimes be hard to initially identify the presence of the disease because some cases are asymptomatic, which means the individual infected may show no symptoms of being ill. Being infected with West Nile Virus can also take those infected down two very different paths, one being the development of West Nile Fever and the other turning into West Nile Disease.

According to the Centers for Disease Control and Prevention (CDC), It is estimated that about 20% of people who become infected with WNV will develop West Nile fever. Symptoms include fever, headache, tiredness, and body aches, occasionally with a skin rash (on the trunk of the body) and swollen lymph glands. While the illness can be as short as a few days, even healthy people have reported being sick for several weeks. The symptoms of severe disease (also called neuroinvasive disease, such as West Nile encephalitis or meningitis or West Nile poliomyelitis) include headache, high fever, neck stiffness, stupor, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis. It is estimated that approximately 1 in 150 persons infected with the West Nile virus will develop a more severe form of disease. Serious illness can occur in people of any age; however people over age 50 and some immunocompromised persons (for example, transplant patients) are at the highest risk for getting severely ill when infected with WNV. Most people (about 4 out of 5) who are infected with West Nile virus will not develop any type of illness (an asymptomatic infection); however you cannot know ahead of time if you’ll get sick or not when infected.

March Showers Bring April Mosquitoes!

The unusually rainy March will most likely increase mosquito populations this spring.  Areas that do not usually flood this late in March are staying plenty moist.  This will allow eggs in those areas a much better chance to survive.  Check out this article. Contact Mosquito Squad for season long protection!

Rain, rain, go away

Southern New Hampshire has received between 4.5 and 9 inches of rain over the last 2 days.  This type of rainfall will create the flood areas needed to allow some forms of mosquito eggs to hatch.  These eggs can go years before hatching.  If the correct (flood) conditions occur they are then able to complete that part of their life cycle.  Keep yourself, your pets, and your family protected.  Mosquito Squad has several ways of keeping mosquitoes away from your property.

The people have spoken

In Tuesday’s elections 6 towns in New Hampshire voted to have monies budgeted for mosquito control.  The most notable being Raymond, where a young girl was stricken with Eastern Equine Encephalitis last year. Mosquito Squad is now available in New Hampshire to help control mosquitos and ticks (lyme’s disease).
