LURE AND KILL : AN UP-TO-DATE, ENVIRO-FRIENDLY COCKROACH CONTROL METHOD

Abstract:
Cockroaches settling down in various sanitary trade institutions, industrial establishments as well as in residential buildings may spread potential infectious diseases and allergy or - through their disgust provoking effect - may disturb people living or working there. As a consequence, regular control of these pests is a must. During the last decade, the fight against German cockroach (Blattella germanica) and Oriental cockroach (Blatta orientalis),t he most common cockroach species in Central Europe, has gone through considerable changes and improvement. Earlier pest controllers tried to eliminate cockroaches mainly by spray or dust formulations applied to the surfaces in large amounts. These methods remain usually ineffective, as the insecticides often have a repellent effect; in some cases, the insecticides get incrusted with fat or dust, or they are removed during cleaning soon. Such control methods have to be considered passive, since it is quite doubtful whether pests get in appropriate contact with the treated surface. Demands to decrease wide-range use of pesticides in human environment and/or to apply formulations as little toxic to the environment as possible, have continuously increased recently. Therefore, in accordance with today's concept, we should attract the insects to the pesticide-free tools (traps) or insecticide containing baits (killing station, gel) instead of getting the insecticide to the insects. The essence of control consists in using the insecticide only on a restricted area and in small quantities. As per the test results presented, for the control according to the lure and kill method are excellently suitable - among others - MEGFOG-LAK B sticky cockroach trap, PROTECT B cockroach killing station having - due to its synthetic pyrethroid content - a fast killing effect, as well as PROTECT B cockroach killing gel, all manufactured by Babolna Bioenvironmental Centre.
