Although insects are an important link in the food chain and are an essential part of the ecological system, nevertheless in the immediate surroundings of humans they can seriously impair health. Insects such as cockroaches, ants and silver fish are therefore not only a nuisance, in many cases they are very harmful. Cockroaches can even transmit germs, mould bacteria and fungus spores to humans. Under the Baygon brand name there are marketed a wide range of different products for the specific and selective control of insects. All the Baygon articles have been biologically and toxicologically tested, and are the results of scientific research. They have different formulations (active and inert ingredients) and different ways of application and specific biological efficacy.
