EW- Earthwood contact is where wooden portions of a structure touch soil or are embedded in concrete / flooring allowing undetectable termite access.
M - Excessive moisture within 3' of a structure provides water for termites and breaks down any termiticide treatment.
F- 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.
J- 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.
