The Florida Department of Agriculture and Consumer Services has found laurel wilt disease on three swamp bay trees in south Miami-Dade County.

Laurel wilt, spread by the redbay ambrosia beetle, attacks members of the laurel family, including avocado.

In March 2010, traps picked up the beetle in the same area in which the disease was confirmed, according to a news release.

The state plans to conduct extensive trapping in the area.
