Termite

 The top signs for termites: 

1. Blisters in Wood Flooring. These areas or blisters can indicate termites feeding within or below.
2. Hollowed or Damaged Wood. Wood damage can be found below and behind surfaces like walls, floors and more.
3. Evidence of Swarms.
4. Mud Tubes. 
5. Drywood Termite Droppings.

Get rid of any decayed lumber or firewood, which termites prefer over sound wood. Warm, dark places: Termites prefer moist, undisturbed places such as crawl spaces

There  are about 45 different kinds of species of termites found in the U.S.,  each of which falls into one of the three main termite types:

• subterranean.
• drywood.
• dampwood.
