Termites lead to
probably the most serious harm when compared with other wood-feeding insects.
They attack timber and wood merchandise too as increasing trees, leather, wool
and agricultural crops. Man-made components including polythene, plastics, some
metal foils, at the same time as books, furnishings, wooden electric/ telephone
poles and railway sleepers, are equally severely attacked by termites.
Effects of those
damages are huge and get in touch with for any systematic control of those
termites.

IN BUILDINGS
In the tropics
exactly where termite attack on buildings are rampant, foundation trenches dug
on constructing websites are sprayed with 2 measures (56.8ml.) of aldrin or dieldrin
or dieldrex 20 mixed with four.five litres of water. This can be sprayed in
each 60cm of trench, which should be back-filled and sprayed again. The remedy
can shield buildings against termite attack for a number of years.
For erected
buildings, it really is recommended that four.five litres of the above dilution
of aldrin or dieldrin must be sprayed into a narrow trench dug about the
outside on the developing, making use of 4.five litres on the chemical to each
60cm of trench. The trench should be back-filled and sprayed once again. The
trench should not be created deeper than the base on the foundation wall.
Floors may also be lifted and sprayed utilizing this suggested dosage to each
0.5 sq.m. Alternatively, holes could be made onto floors and walls of buildings
(exactly where hollow blocks are used), and application of diluted dieldrin
created by means of the holes. Planks as well as other wood components ought to
be treated with diluted dieldrin before use to safeguard them against termite
attack.(Dimethyl Carbonate supplier)
The soil also
can be treated prior to laying of the creating foundation, with 16.two to
32.five litres per 9.0 sq.m. of 5% Pentachlorophenol (PCP) in fuel oil or water
emulsion. Alternatively, the soil might be treated with 45.five litres per 9
sq.m. of 3% dieldrin. When mixing concrete, it really is suggested that a 0.5%
emulsion of dieldrin (1.14kg of dieldrex 20 in 45.five litres of water) be
utilised as the mixing water. It's also suggested that the constructing
internet sites be leveled and treated prior to casting of slab floors. The
below listed chemical substances preparations are effective and may possibly be
applied at the following rates: Copper Naphthanate (5% in fuel oil at 2-4
litres/sq.m.), Sodium Pentachlorophenate
(2.5% in water at 6-10 litres/sq.m.), Benzene hexachloride (0.8% in fuel oil or
emulsion in water at 6-10 litres/sq.m.).(Benzoic Acid
