Termite Control Tactics
• Possible Strategies
– Physical
– Cultural
– Biological
– Chemical
• Wood Treatments
• Soil Barriers
• Baits

Cultural Controls
• Avoid wood-to-soil contact
– Log piles against structures
– Construction debris
– Backfill/front stoop shouldn’t contain wood
• Moisture management
– Drainage away from foundation
– Gutters, downspouts well-maintained

Physical Control
• Barriers to tunneling
– Sand, basalt, granite, glass, etc.
– Grain size of 2.0-2.8 mm.
– 20cm thick.
– Stainless Steel Mesh
• Termi-Mesh
– Thick rubber mats
• Pre-construction only

Biological Controls
• Nematodes (Steinernema)
– Not effective against subterranean termites in field
trials
• Fungi (Metarhizium)
– More successful than nematodes
– Bio-Blast (Paragon Professional)
– applied as a dust/WP
• Bacteria (Bacillus)
– Has been studied, but not currently used

Chemical Controls
• Wood Treatments
– Reduce feeding on structural wood
– Pressure treatments or spray-on
• Products
– BoraCare/Jecta (Nisus) www.nisuscorp.com
• disodium octaborate tetrahydrate
– Tim-bor (U.S. Borax) www.borax.com
• disodium octaborate tetrahydrate

Chemical Controls
• Chemical Barriers
– Applied to soil around structures
– 4gal./10ft./1ft.depth
– Restricted-use chemicals only
• Repellent vs. Non-repellent?

Why Soil Barriers?
• To protect areas of the structure where
termites are likely to enter.

Subterranean Termite Control
• Repellent vs. Non-repellents?
– Repellent (Pyrethroids)
• Termites detect and move away from treated soil
• No mortality
– Non-repellent (Various)
• Termites don’t detect treated soil and enter
• Mortality results

Termidor PerimeterPLUS label
• Exterior perimeter
– MUST Trench/rod along foundation wall
– MUST Drill/rod adjoining slabs/patios
• PLUS
– MUST treat active sites indoors (+2ft in at least two
directions).
– MAY treat susceptible areas
• Original label directions for spot/partial/full
treatments still valid

Chemical Controls
• Managing Reticulitermes Using Baits
– Just ‘killing the queen’ doesn’t work
– Centers of activity change in habitat
– Splitting colonies can occur using soil
termiticides
– Termite baits seek to address colony networks

Why Baiting?
• To reduce the number of subterranean
termites in the vicinity of a structure.
Kansas IPM Education

Baiting Methods
Four basic methods have been examined:
1. Monitoring stations followed by consumable
bait when termites are located
2. Consumable bait in stations prior to
detection
3. Consumable bait at the site of infestation
4. Trapping followed by groomable coating
applications and release back into station

Baiting Strategies
• Areas where foraging is likely
– Temperature and moisture consistent
– Food sources nearby
– Active sites are best
• Do not want to disrupt foraging/feeding
• Distance between stations
– Clustered stations
Kansas IPM Education

Baiting Systems
• Design considerations
– Disturbance at station
– Monitor integrity/acceptance
– Type of active ingredient
• Palatability of active ingredient
• Metabolism of active ingredient
– Bait matrix
