The product MDHHS is using for aerial treatment is called Merus 3.0. It will be sprayed by a low-flying aircraft at a very low volume of around one tablespoon per acre. Merus 3.0 is registered with the EPA. It is labeled for public health use over residential areas and is approved for use over organic crops.

No short-term or long-term risks to human health are expected during or after spraying. While it is not necessary to bring animals indoors during spraying, concerned pet owners can bring animals inside during spraying.

Application conducted at night will minimize risk to daytime foragers such as bees. The product will dry quickly and should not pose long term risk. Beekeepers wanting to further minimize the risk that the product would be drawn into a colony can reduce entrances to their colonies to minimize air movement into the colony, or cover colonies during an application using a damp cloth — burlap is often recommended.

Similar products are used and have been proved effective in other states, including Massachusetts. In Massachusetts, officials have been monitoring approximately 600 honeybee colonies and have not observed problems.

Large water bodies will be avoided by MDHHS during spraying. The active ingredients in Merus 3.0 break down rapidly in surface water and are not expected to cause adverse effects.
