Commercially Available Drywood Termite Management Options.


Treatment Efficacy in Field Strengths Considerations
/Limitations
Damage to Structure


EXISTING INFESTATIONS
Whole-Structure


Fumigants up to 100%
1,2,3
Hidden sites treated correct dosage must be achieved; residents must leave house; no residual Gas pilots must be extinguished before treatment; possible damage to roof from tarpaulins or if walked on


Heat up to 100%
2
Hidden sites treated Lethal temperature must be achieved in the core of all infested wood; no residual; heat sinks may affect efficacy Possible damage to roof if walked on and for some heat-sensitive household items


Localized/Spot Treatments
Chemical


Chemical liquids
& dusts
up to 90%
3
Long Term Few active ingredients commercially available; detection accuracy critical; chemical residual; results vary with active ingredient used and concentration; infestation may rebound yes, if drill holes used


Chemical Foams no information
coverage of hidden infestation, long-term no published efficacy studies yes, drilling holes


Liquid Nitrogen 74 to 100%
2
benign material highly dependent on dosage; detection accuracy critical; no residual yes, drill holes


Non-chemical


Biological Control no information no chemicals few commercially available; research needed don't know


Electrocution 44 to 98%
2
portable detection accuracy critical; many disclaimers; infestation may rebound yes, if drill holes used


Heat up to 100%
2
semi-portable lethal temperature must be achieved in the core of all infested wood; no residual; heat sinks may affect efficacy may be to wood or heat-sensitive household items


Microwaves 89 to 98%
2
semi-portable detection accuracy critical; highly dependent on treatment time and wattage; heat sinks may affect efficacy may be to wood or household items


PREVENTIVE


Chemical liquids & dusts up to 90%
3
long-term few active ingredients available; chemical residual; results vary depending on active ingredient used and concentration; infestation may rebound yes, if drill holes used


Pressure-Treated Wood no information
long-term few active ingredients commercially available; chemical residual; results vary with active ingredient used and concentration; environmental persistence no


Non-chemical


Barriers (screens/paint) no information
long-term barriers degrade & can be breached; some feeding damage may occur no


Resistant Woods no information
long-term efficacy highly variable depending on species of wood; costly; availability; some feeding damage may occur no
