DIELDREX TC*

Dieldrin, the active ingredient in DIELDREX TC provides long residual action in treated soil for protecting both new and estab lished buildings against sublerranean termites. Recommendations:

1. Apply Dieldrex TC under and around foundations before erection of buildings, as termites cannot survive in or penetrate treated soil.

2.

Add Dieldrex TC to mixing water for concrete, to prevent termite entry through cracks developing in concrete slab of floors.

3. Spray or inject Dieldrex TC under floors and around foundations

for termite control in existing buildings.

Note faulty brick foundations through which subterranean tərə

mites easily pass to vulnerable wooden super structure.
