Regular inspections by a pest control company or do it yourself, if qualified.
Eliminate Conducive Conditions:
Earthwood contact is where wooden portions of a structure touch soil or are embedded in concrete / flooring allowing undetectable termite access.
Excessive moisture within 3' of a structure provides water for termites and breaks down any termiticide treatment.
Foliage( trees, shrubs, etc. ) within 3' of a structure reduces visual access, provides food source and may breach any termitcide barrier via the root system.
Blind joints are areas where two concrete slabs meet and are blocked from visual access by wood or other material. This condition allows undetectable termite entry.
Hollow tile walls allow undetectable termite access via void chambers.
Stucco siding embedded in the soil or concrete allows undetectable termite access.
Concrete cracks in excess of 1/16" allow undetectable termite entry..
Wood debris or other cellulose containing material should not abut the structure
You may use both termite baits and termite chemicals together if using a non-repellent termticide.
Drywood Termites
Evidence of Activity:
Their fecal material looks "sand like". Kick-out holes on the walls, ceilings or wood. Infestation may take two years before evidence of droppings is present.
Prevention:
Use treated lumber during construction.
Coat any untreated wood or exposed wood with Boracare or Timbor.
Seal all cracks and crevives with caulking.
Control:
For complete treatment, use tent fumigation from a professional termite company.
