Against flies and other flying insects: dilute in water using 2% PERTRIN S for normal infestations and as a maintenance dose, or 3% for heavy infestations or to obtain a greater residual effect.
Then apply the emulsion thus obtained with normal hand or mechanical sprayers, both cold and hot, on the surfaces infested by insects, distributing approximately 1 litre of emulsion every 15 m2.
For outdoor treatments and in particular for the adulticidal control of mosquitoes, PERTRIN S can be used in percentages ranging from 0.25% to 0.5% (250 – 500 ml in 100 litres of water).
Against cockroaches and other crawling insects: dilute in water using 4% PERTRIN S, or 5% in case of heavy infestations.
Then apply the emulsion thus obtained using normal sprayers on the surfaces infested by insects (in particular under sinks, wall baseboards, cracks, crevices, etc.), distributing approximately 1 litre of emulsion every 15 m2.
