A study was conducted to investigate the direction of foraging of the termites towards a farm building (Entomological Research Laboratories, ERL) and efficacy of soil barrier inside this farm building at Post Graduate Research Station, Faisalabad, Pakistan. Foraging of the termites was determined by installing equally spaced PVC pipes with corrugated cardboard in them around building. Soil barrier of the most efficacious insecticide from bioassay test was created around a pit (0.48 m, 0.32 m width and 0.4 m deep) inside ERL. Chlorpyrifos and alpha cypermethrin proved the most effective against termites with LT50 of 3 hours each at a concentration of 1200 ppm. Foraging of termites from mulberry plantation was highest than from fallow field side towards the building. Soil barrier could prevent penetration of the insecticide mixed soil for only up to 15 days when 0.33% damage of wood pieces was observed. Application of soil barrier in an outdoor setting under local conditions against the termites is discussed.
