Zika Risk Reduced By Mosquito Spraying

In a new study published looked at 50 U.S. cities where the weather could support Aedes aegypti (the yellow fever mosquito that spreads Zika and other dangerous diseases) in warmer months.

Cities at Risk

Yellow cities are low-risk, orange are moderate, and red are high. The size of the dot over the city represents how many travelers from current Zika-affected countries come to the city on average each month. And the gray zone represents the area where Aedes aegypti has been observed in earlier years.

How Risk Was Calculated

To determine which cities would be most at risk and when, the researchers examined a number of factors:

  • The estimated abundance of Aedes aegypti mosquitoes per square meter of standing water, based on their life cycle and the historical meteorological conditions in each city (from 2005 to 2015)
  • The number of travelers arriving in those cities from Latin American countries currently affected by Zika (although the researchers do note that some people on those flights may have just connected through a Zika-affected country)
  • Previous cases of locally transmitted dengue and chikungunya, two other diseases transmitted by Aedes aegypti
  • Percentage of households in each city living under the poverty line, which makes people less likely to have air conditioning (Aedes aegypti doesn’t survive well in air-conditioned buildings), safe water, and good sanitation.
  • Irregular garbage collection in some areas may also provide opportunities for the bug to breed.)
  • Observations from 1960 to 2014 of the mosquito’s maximum geographic range

Expected To Spread

Based on their estimates, this is how the year plays out in terms of highest risk for abundant Aedes aegypti populations:

Mosquito Spraying Helps Prevention

It’s also worth noting that the models don’t account for mosquito-control methods—so there’s still plenty of room to bring this risk down by spraying for adult mosquitoes, using larvicides, and eliminating mosquito-breeding sites, particularly standing water.

Fleas threaten both pets and humans when they emerge in the spring and summer months. While they only live for 100 days, they can produce 400 to 500 babies in that time. These new fleas can spread awful illnesses to you, your family and your pets. Fortunately, vacuuming often can be an easy and effective defense against these bloodsucking pests.


Mosquitoes are the most well-known pest of summer, but can also be the most dangerous in terms of illnesses. With 170 different mosquito species in the United States alone, the risk of being bitten is high. It is important to know how to prevent mosquito bites, and protect yourself and others from illnesses such as West Nile Virus and encephalitis. When outdoors, use an insect repellant and wear clothing that covers the arms and legs. To prevent mosquito breeding around your home, clear all standing water from your property.


In summer, ticks are often seen as public enemy number one. Carrying Lyme disease and other illnesses, various species of ticks plague nearly all wooded areas of the United States. Knowing how to protect yourself, your family and your pets is necessary to enjoy the summer months. When you are in wooded areas or areas with brush, be sure to wear long sleeves and pants to keep ticks off of your skin. Be sure to inspect your pets, as well. The ears and noses of pets are often the ideal spot for ticks to attach, and later enter your home.

Kissing Bugs

Despite their name, kissing bugs are not the most loving of the insect world. They often enter homes through unsealed openings and bite their victims at night. Kissing bugs are dangerous, as they have been known to transmit parasitic illnesses like Chagas disease. Preventing kissing bugs is often quick and easy. Sealing up any cracks, holes or other openings in the outside of your home will keep these bloodsuckers at bay.

Chicken Mites

If you have a bird nest near your home, you may be at risk for chicken mites. While not widely known, they live on a variety of birds, including sparrows and pigeons. They migrate from the nests of these birds into your home. Their bites can cause a painful skin rash for human victims. To prevent chicken mites in your home, avoid handling bird nests on your property, even if they are empty. Also remember to check your pets if they are allowed in areas where birds have built nests.

If you believe you may have an insect infestation in your home or simply need help preventing a pest problem, call the professionals at Reardon today 302-792-9300 or contact us online.

Hot Humid Summer Impacts Fall and Winter Pest Population

The National Pest Management Association recently released its Bug Barometer, a forecast indicating what Americans can expect from pest populations this fall and winter. NPMA’s Bug Barometer takes into account the weather patterns of the summer season in every region of the country.

Spring and summer are typically the most active seasons for the majority of pests, such as ticks, mosquitoes and ants, and this year was no exception. Unfortunately, the start of fall doesn’t necessarily mean an end to pest activity, with many of these pests remaining active until temperatures consistently stay below the 50-degree mark and they begin to seek overwintering sites.

After winter storms and frigid cold battered the Northeast earlier this year, consistent warmth made May one of the warmest on record for many cities. That was followed by periods of record-setting rainfall and exceptional humidity, which combined with the heat to provide ideal conditions for pests. Mosquitoes, especially, are expected to take advantage of an increase in areas of standing water and remain active until temperatures consistently dip below 50 degrees. The summer conditions have also helped tick populations to remain at average levels, where they will remain well into the fall season. The heat and humidity have also benefitted overwintering pests, such as brown stink bugs and multicolored Asian lady beetles that will begin to gather on exterior walls as they search for winter shelter in the coming months.

Four Delawareans Test Positive for West Nile Virus

Four people in Delaware have tested positive for the West Nile Virus. Three were in New Castle County and one in Kent County.

Mosquitoes have been bad this summer because of early, heavy rains and are expected to spread the virus until cold weather arrives.
