Types of Termites



 Learning Levels 4-5
                Types of Termites
All termite species are categorized into one of three termite
      types based on their feeding and habitat preferences:

1.   Drywood Termites
2.   Ground (subterranean) Termites
3.   Dampwood Termites

     We will only be discussing drywood termites and
     ground termites because they are the types which
     inhabit and cause damage to human homes.
     Dampwood termites are rarely found in urban areas
     and prefer to make their home in damp, rotting wood
     logs in forested areas.
 Why Learn About the Types of Termites?

1. All termite species within each group
   share important characteristics
2. Between the types there are many
   differences
3. Each type of termite requires different
   treatment approaches based on whether
   they live outside or inside the home.
                    All Termites…

1.   Are social insects
2.   Have different family members with different colony
     jobs
3.   Eat wood along with other plant parts containing
     cellulose (main component in plant cell walls)
4.   Prefer to live in the dark
5.   Need water, food and shelter in order to survive

 Now that we know some things that all termites have in
   common let’s look at some of the differences between
   the types of termites…
               Drywood Termites
• Build colonies inside the
  wood they eat
• Small families ranging
  from a few hundred to a
  few thousand
• Eat less than a pound of
  wood per year per colony
• Keep to small areas such
  as pieces of furniture,
  doorways or windowsills
• Many drywood termite
  colonies can live in a
  house at the same time
                              Drywood Termite Soldier
Ground Termites
         • Build their colonies beneath
           the wood they eat
         • Large families having an
           average of 3-5 million
           members, and in the right
           conditions can grow to as
           large as 10 million
         • Have healthy appetites and
           lots of mouth to feed, an
           average colony can eat 1,000
           pounds of wood each year
         • Colonies can get as long as a
           football field and as deep as
           20 feet into the ground
                Termite Clues

    Most of the time we do not see termites…only
    what they leave behind. Check out the termite
   clues for both drywood and ground termites, so
that you can become a termite detective and stop the
  mighty munchers before they eat you out of house
                      and home!
        Drywood Termites


            Many Veined
              Wings


FRASS                       Kick-Out Holes




                          Odd-shaped Patterns
• FRASS: Sand-like droppings that are pushed out
  of the drywood termite colony. Frass can appear
  in many shades of brown and black depending
  on the color of the wood being eaten.
• ODD-SHAPED PATTERNS: Drywood termites
  like both hard and soft wood. They are non-picky
  eaters and leave odd-shaped patterns in the
  wood they eat.
• KICK-OUT HOLES: Tiny pin-sized openings
  made by drywood termites. Drywood Termites
  use these holes to push their frass out of their
  colony.
• WINGS: Drywood Termite Alate wings have
  many veins on the top side. Their wings also
  have a rainbow reflection, similar to the look of
  oil on water.
              Ground Termites


                 Single Veined
                     Wings


Mud Tunnels                         Carton




                                 Line Patterns
• CARTON: Made mainly from waste, soil and
  saliva. It is left behind in the wood eaten by
  ground termites. Carton is also built within the
  colony as a living space because it helps to
  maintain a moist, warm environment.
• LINE PATTERNS: Ground Termites like soft
  wood only. They are picky eaters and leave line
  patterns in the wood they eat.
• WINGS: Ground Termite Alate wings have only
  two veins that run side by side along the top of
  the wing. Their wings are dull colored with no
  rainbow reflection.
• MUD TUNNELS: Protective pathway from a
  ground termite colony to their aboveground food
  source. Mud tunnels protect termites from light,
  heat and wind.
      Know Your Termite Clues
   Carefully look at the provided termite
damage samples. Practice identifying each
   sample and to which type of termite it
  belongs. Put your new termite detective
 skills to good use around your own home
and see if you can uncover any unwanted
             visitors. Good Luck!
