Zenivex\u00ae does not require a synergist such as piperonyl butoxide. The U.S. Environmental Protection Agency (EPA) has classified Etofenprox as a reduced risk pesticide. It poses a low risk to human health and the environment when used properly as part of an integrated mosquito control program. As formulated in Zenivex\u00ae adulticide, Etofenprox is considered a non-carcinogen, non-teratogen and non-mutagen.&nbsp;<\/span><\/p>\n<p style=\"margin: 0in;\"><span style=\"font-family: 'Calibri',sans-serif; color: black;\">&nbsp;<\/span><\/p>\n<p style=\"margin: 0in;\"><span style=\"font-family: 'Calibri',sans-serif; color: black;\">Zenivex presents a minimal risk to humans, pets and non-target species. Etofenprox presents a low toxicity to birds and dried foliar residues are not harmful to honeybees. Applications occur after sunset when honeybees aren&#8217;t active. Zenivex E4 is toxic to fish, but buffer zones are in place to avoid spraying around fish habitat.<\/span><\/p>\n<p style=\"margin: 0in;\"><span style=\"font-family: 'Calibri',sans-serif; color: black;\">&nbsp;<\/span><\/p>\n<p style=\"margin: 0in;\"><span style=\"font-family: 'Calibri',sans-serif; color: black;\">This pesticide kills mosquitoes effectively, yet biodegrades rapidly in the presence of sunlight and\/or microorganisms.<\/span><\/p>\n<p style=\"margin: 0in;\"><span style=\"font-family: 'Calibri',sans-serif; color: black;\">&nbsp;<\/span><\/p>\n<p style=\"margin: 0in;\"><span style=\"font-family: 'Calibri',sans-serif; color: black;\">Etofenprox is readily found in flea and tick prevention treatments for dogs and puppies, and at much higher concentrations than what is used for mosquito control.<\/span><\/p>\n<p>____________________________________________________<\/p>\n<p>&nbsp;<\/p>\n<p>East Middlesex is applying Zenivex E4 at a rate of around 1 oz. per acre, which is equivalent to about two tablespoons per acre. The active ingredient, etofenprox, makes up 4% of that amount, therefore, less than 1\/10th of a tablespoon of the active ingredient is being applied per acre.<\/p>\n<p>An Ultra Low Volume sprayer located in the back of a pick-up truck is used for the mosquito control effort. The average droplet size of the spray falls between 10-30 microns. A micron is 1\/25,000 of an inch. For perspective, human hair is 100 microns.&nbsp;<\/p>\n<p>Mosquitoes are the target. Being that mosquitoes are so small, only a small amount of Zenivex E4 is needed to reduce mosquito populations. The small amount needed to reduce mosquito populations is not expected to have negative impacts on non-target animals or the environment.&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>EPA Information on Mosquito Control<\/p>\n<p><a href=\"https:\/\/www.epa.gov\/mosquitocontrol\">https:\/\/www.epa.gov\/mosquitocontrol<\/a><\/p>\n<p>&nbsp;<\/p>\n<p><strong>Label and Material Safety Data Sheets (MSDS)<\/strong><br \/>\n<a href=\"https:\/\/www.centralmosquitocontrol.com\/all-products\/zenivex\/zenivex-e4-rtu\">-Zenivex E4<\/a><br \/>\n&nbsp;<br \/>\n&nbsp;<br \/>\n&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Zenivex E4 What is Zenivex\u00ae adulticide and how is it used?&nbsp; &nbsp; Zenivex\u00ae contains a pesticide called Etofenprox, a member of the category of pesticides called non-ester pyrethroids, which are synthetic versions of pesticides produced &hellip; <a href=\"https:\/\/sudbury.ma.us\/emmcp\/admosqpest\/\" aria-label=\"Read full article about Adult Mosquito Control Pesticides\">Read full article<span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"inline_featured_image":false},"_links":{"self":[{"href":"https:\/\/sudbury.ma.us\/emmcp\/wp-json\/wp\/v2\/pages\/38"}],"collection":[{"href":"https:\/\/sudbury.ma.us\/emmcp\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/sudbury.ma.us\/emmcp\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/sudbury.ma.us\/emmcp\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/sudbury.ma.us\/emmcp\/wp-json\/wp\/v2\/comments?post=38"}],"version-history":[{"count":9,"href":"https:\/\/sudbury.ma.us\/emmcp\/wp-json\/wp\/v2\/pages\/38\/revisions"}],"predecessor-version":[{"id":1076,"href":"https:\/\/sudbury.ma.us\/emmcp\/wp-json\/wp\/v2\/pages\/38\/revisions\/1076"}],"wp:attachment":[{"href":"https:\/\/sudbury.ma.us\/emmcp\/wp-json\/wp\/v2\/media?parent=38"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
