When do termites swarm in Florida?

Sunday, July 15, 2018

There are two types of termites that can damage your home: subterranean and drywood. Subterranean termites live in the soil, are water-dependent, and build mud tubes up into the structure. The are the more aggressively destructive than drywoods and usually swarm from mid-December to mid-May, in the morning and often when the ground is moist after a rain. Peak activity is in February and March.

    Drywood termites do not need a water source and live in the wood inside the walls and attic of your home. They typically swarm from April to July, usually in the early evening.

    When there is an active infestation in your home and they swarm inside the structure, it can be a a horrifying event, with thousands of what appear to be small flying ants covering a room. The best way to avoid a termite invasion is to eliminate conditions that make it easy for termites to reach the two things they need—wood (cellulose) with moisture nearby—in your home.

    If you look closely at a winged swarmer, you can determine if it is a termite or ant by the shape of their body. Ants have a narrow waist between body segments and termites do not. Termites have straight antennae, and ants have angled antennae.

    Here’s some suggestions from the University of Florida’s IFAS Extension for keeping termites away:

  •  Building woodwork such as wood-siding should be a minimum of 6 inches above ground to prevent wood-to-ground contact.
  •  Any wood that contacts soil such as fence posts, deck poles, or other foundation structures should be commercially pressure treated and should not contact the house.
  •  Adjust sprinklers so they do not spray directly onto the structure.
  •  Channel all gutter down-spouts at least 2 feet away from the foundation of the home.
  •  Landscape plants should not be placed within 2 feet of the foundation.
  •  Remove old stumps, roots, downed branches, and other decaying vegetation from around the structure.
  •  Store firewood and excess building materials off of the ground and away from the house.
