TermitesO 45 species of termites in US
O Only 2 species are native
TermitesO Gut symbionts help digest cellulose
(wood)O Bacteria and protozoans
TermitesO Mature queen lays up to 10,000 eggs
per weekO She can live 10 years or more
O That’s 60 million eggs
Termites and AntsO Both swarm same time of year
O When reproductive take flightO Start new colony
Termites and AntsO Ants have constricted “waist”
O Between thorax and abdomen
TermitesO Spread chemical messages through
frequent groomingO Anal trophallaxis
O Fluids exchange anus to mouth
O Also transfers gut symbionts through colony
Caste SystemO Reproductive Castes
O Produce a queen
Caste SystemO Worker Caste
O Food, grooming
Caste SystemO Soldier Caste
O Enlarged mandibles
MoistureO Carry moist soil above ground
O Mud tubesO Keep termites moist
MoistureO Cemented with
saliva and fecal matterO Mud left behind
in wood
MoistureO Leaky pipesO Wet areasO Shrubs
against house
FoodO Radial paths spreading from colony
in search of foodO Spokes on wheel
O Can’t find food, likely bump into it
FoodO Cellulose is food source
O Untreated woodO Trees, stumps, firewood,
O Attracted to partially decomposed wood
FoodO Eat softer spring wood in growth
ringsO Leave harder summer wood
O Only eat 20% of total woodO Lattice symptom
FoodO Mud left in
tunnelsO Carpenter ants
leave clean tunnels
InspectionO Shed wings or dead swarmer
termitesO Window sills
O Mud tubesO Tiny holes in baseboards
O Hollow thump
PreventionO Eliminate wood to
ground contactO 90% of
infestationsO Firewood away
from houseO Untreated wood 6”
above groundO Use treated wood
for ground contact
Control
Termiticide TreatmentsO Chemical barrier
around houseO Trenching and
roddingO Slabs are drilled and
injected
ControlBait StationsO A non-lethal
food source around houseO Stations every
10’ to 15’O 12” to 18”
from houseO Frequently
monitored
Control
Bait StationsO If termites are present, non-lethal food
source replaced with poison baitO Slow-acting poison taken back to colony
PreventionO Keep vegetation
and mulch away from house
O Mulch serves as a moisture conduitO Mulch not a food
sourceO Even pea gravel
PreventionO Gutters and downspouts away from
house
