Top Termite Cities Revealed

This spring, seal cracks and openings where insects can enter your facility

March 8, 2019

Facility managers may want to keep an eye out for damp areas around their buildings as well as foundation cracks where insects and other pests can enter. Spring brings swarms of termites seeking wood, and your facility may be at risk.

Exterminators treated the most termite cases in Miami, FL, followed by Los Angeles, CA; Tampa, FL; New York, NY; and New Orleans, LA; according to a news release from Orkin based on data where the company performed the most first-time termite treatments from February 1, 2018 to January 31, 2019.

All areas of the United States are prone to subterranean termites, with drywood termites a threat along the Pacific and Southeast coasts. Subterranean termites swarm in the spring and summer, while drywood termites typically swarm during the late summer or fall.

Termites are attracted to dead trees, but with fewer trees around due to urbanization, termites will find their way to other sources of wood such as residential and commercial facilities. These insects can hide in your facility without any immediate signs of damage for years. They enter buildings through cracks or gaps around pipes and wires, as well as foundation cracks as small as 1/32 of an inch—about the thickness of a business card.

Termites thrive in damp conditions. Buildings at risk of termite invasion have damp soil near the foundation from leaking faucets, gutters, or downspouts, and often have trees or shrubs nearby.

Orkin recommends that facility managers look for signs of a termite infestation:

  • A temporary swarm of winged insects in your building or from the soil around your building
  • Cracked or bubbling paint
  • Wood that sounds hollow when tapped
  • Mud tubes on exterior walls, wooden beams, or in crawl spaces
  • Discarded wings from swarmers.

Orkin recommends the following strategies to prevent termites from entering your building:

  • Check water drainage sites to ensure they remain cleared and effective.
  • Monitor the collection of moisture by fixing pipes, gutters, downspouts, air conditioning units, and other fixtures susceptible to leaking.
  • Caulk around utility lines or pipes.
  • Place screens on outside vents.
  • Check wooden structures for damage.
