Zika Virus: Barrier Applications are Key to Reducing Aedes Mosquitoes Populations
In the early 2000s, mosquitoes were the center of attention due to a West Nile outbreak in the U.S. More than fifteen years later, mosquitoes are once again in the national spotlight are many of our customers are calling and asking what can be done to control them.
This recent concern is due to the Zika virus, a disease transmitted through the bite of an infected mosquito that may have an association between infections in pregnant women and birth defects. In 2015, Zika outbreaks were reported in the Western Hemisphere, for the first time in Central and South America, the Caribbean and Mexico. Most recently, cases have been reported in Florida. According to the Centers for Disease Control and Prevention (CDC), Zika transmissions are expected to increase throughout the region, increasing the incidence of infection in returning travelers and the possibility of local transmission in the U.S.
The principle mosquitoes of concern are the yellow fever mosquito (Aedes egypti) and its close relative, the Asian tiger mosquito (Aedes albopictus). These mosquitoes readily feed on humans and are closely associated with human habitats, often laying their eggs in containers that are manmade (such as tires and rain gutters), or natural (such as tire holes). Adult mosquitoes tend to rest in vegetation when they are not seeking a blood meal.
Traditional mosquito control methods of truck-mounted and aerial sprays have proven ineffective in controlling Aedes mosquitoes. Barrier treatments, however, are an effective and proven method of managing these pests.
• A barrier application can be made by treating all vegetation, including but not limited to trees, bushes, and shrubbery from the ground level up to a height of about 10 feet with a residual insecticide labeled for mosquitoes.
• Backpack misters are ideal for these applications as they forcibly disperse droplets onto dense vegetation and underneath leaves.
• Other common mosquito resting sites including under decks, near drainage spouts, and other shady, moist areas, should be included in the barrier treatment area.
To effectively manage mosquito populations, the Rainy Season Mosquito Reduction program from Vulcan Pest Control can provide your property a significant reduction in mosquito populations for 30-60 days. The program protocol calls for the use of a microencapsulated adulticide plus an insect growth regulator. The adulticide targets adult mosquitoes and the insect growth regulators interrupts the life cycle of m osquitoes, causing them to lay non-viable eggs and preventing larvae from developing into adults.
Be prepared for mosquitoes this season with the right program and appropriate tools. For more information and a free, no obligation evaluation of your situation, call us at (561) 791-2400.
