This time of the year working in the nursery can be tough. Heat, rain, lightning, tropical storms, and biting insects all take their toll. We can control the weather but you can alleviate the mosquito bites. Here is an article from Chemically Speaking newsletter from the Pesticide Information Office.
The EPA has recently updated its insect repellent Web page (http://www.epa.gov/repellentfinder). By reading and following label directions, the use of repellents can reduce or eliminate the discomfort of insect bites. Ticks can transmit serious diseases such as lyme disease, Rocky Mountain spotted fever, and other serious diseases. Repellents also curtail the spread of such mosquito-borne diseases as St. Louis encephalitis and West Nile virus. The Web page serves as a one-stop-shop for information on registered repellents. It provides up-to-date listings of mosquito and tick repellents as well as tips for choosing the right product. One of the key features of the revamped site is easy access to information about protection time. It will help people choose the right product for the length of time they will be outdoors. (EPA, 5/18/10).
I hope that this info helps you to make better decisions when battling mosquitoes in the nursery. Also remember to make sure that stored, used containers and any old tires are stacked or covered to eliminate water puddling and creating breeding grounds for mosquitoes.
