- Insects especially in interiors
- These new compositions are characterized in that they contain at least one type of insecticide which is incorporated into a suitable silicone elastomer
- the silicone elastomers according to the invention are distinguished by the fact that they are capable of continuously releasing the insecticides contained, with or without heating, without their shape changing. In this way, the greatest possible action and duration of action are achieved with little expenditure of energy.
- the use of these new ones Insecticidal formulation against all flying insects, in particular biting mosquitoes, biting flies etc. should be carried out without the use of any type of container, if necessary by heating the suitable insecticide-containing silicone elastomer in a suitable heating apparatus
