The Guard 'n' Aid Midi Fumer is an alternative pest killer to all the spray on methods. When used properly and in the right quantity the midi fumer will be more effective at clearing the room and any plants inside than a liquid pesticide. This is due to the fact that invariably when spraying you will miss areas, and its not always convenient to spray on surfaces. These fumers are excellent at clearing the whole room and its contents of any insects.
Apply at a rate of one generator per: 500m³ for flying insects 125m³ for fleas and bed bugs 31.5³ for ants and cockroaches Further instructions come with the fumers, read and use with caution.
