It’s that time of the year again when mosquitos are forcing you inside and you can’t enjoy your porch or deck. The Centers for Disease Control (CDC) states that mosquito-borne diseases are spreading quickly around the United States. Many homeowners resort to spraying because it is a quick and obvious response. The environmental Protection Agency (EPA) and CDC do not recommend spraying due to the possible exposure to potentially dangerous pesticides and to the impact on pollinating insects such as honey bees, wild bees and butterflies that play an important role in the availability of many agricultural products.Pesticides, alone and in combination with other factors, have had a devastating effect on honeybees and wild pollinators. Pesticides commonly found in lawn and garden products and used in agriculture are known to be hazardous to bees – some killing bees outright and others with subtle effects that reduce a bee’s ability to thrive. Approximately 90 percent of all flowering plants require pollinators to survive. In agriculture, nearly a third of pollination is accomplished by honeybees. Cucumbers, almonds, carrots, melons, apricots, cherries, pears, apples, prunes, plums, cantaloupe, onions, avocados, kiwi, blueberries, cranberries and more depend on honeybee pollination.The Maryland Department of Agriculture’s (MDA) Mosquito Control Section is responsible for administering and implementing mosquito control within the State of Maryland. The State works closely with the Montgomery County Mosquito Control Program. Mosquito season typically runs from late May to early October. During this time, the State and County mosquito control program conducts a variety of routine activities including arboviral surveillance and testing, mosquito population surveillance activities, source reduction, biological control initiatives, ground and aerial application of insecticides, and public education. Mosquitoes undergo four life stages: egg, larva, pupa, and adult. Disrupting a mosquitos' life cycle and habitat may reduce the number of mosquitoes around you and your environment. There are steps you can take to reduce mosquito populations before choosing to use a pesticide product. If you choose to use an insecticide, be sure to read and follow all label directions. Some products are designed to be applied directly to water to control mosquito larvae, while others are used more broadly to control adult mosquitoes.Tips to Rid Your Home of Mosquito Breeding Sites
SprayingShould you choose to hire a contractor to spray around your home to deter mosquitos, you should make sure that the company is licensed to apply pesticides in Maryland. The Maryland Department of Agriculture (MDA) is the licensing body and it has a web tool where a user can enter the name of a company to determine if it is licensed.Broader-scale spraying of mosquitos may be performed by the MDA or other public agencies when other mosquito controls are not possible or are not effective in reducing mosquitos below a level that may cause unacceptable annoyance or a public health threat.
