Spotted lanternflies are expected to overrun New York by the end of May, following a population dip in 2022 and 2023. These invasive insects, known for their red and tan wings with black spots, primarily feed on the Tree of Heaven but can also damage various crops and plants, including grapes and fruit trees. Their presence poses a significant threat to New York's agricultural and tourism industries.

The New York Department of Environmental Conservation (DEC) and the Department of Agriculture and Markets are urging residents to help stop the spread of these pests by squishing them on sight. The lanternflies have a "boom and bust" cycle, where they deplete their main food source one year, leading to a population surge the next year.

According to the DEC, the spotted lanternfly was first discovered in New York in 2020, with the initial infestation found in Staten Island. Since then, the insect has spread across the state, including all New York City boroughs and several upstate regions. The DEC and its partners are conducting extensive surveys and inspections to detect and manage infestations early.

The New York State Department of Agriculture and Markets emphasizes the importance of scraping egg masses from surfaces to prevent the spread. The lanternflies lay eggs on various surfaces, including vehicles and outdoor furniture, which can inadvertently transport them to new areas. The department also advises travelers to inspect their belongings for egg masses before leaving infested areas.

The economic impact of the spotted lanternfly could be substantial, potentially costing New York State up to $300 million annually, mainly affecting the grape and wine industry. The DEC and other agencies continue to work with national and local partners to mitigate the spread and protect vulnerable areas.
