Using natural insecticides indoors offers a number of benefits. They are safer to use than synthetic chemicals and can be used without worrying about any long-term health effects. Natural insecticides are also generally less expensive than their chemical counterparts, making them an affordable option for controlling indoor pests. Natural insecticides break down more quickly in the environment and do not leave behind harmful residues like chemical ones do. This means that there is less chance of contamination in the soil or water supply from using these products indoors. Natural insecticides have been found to be effective at controlling many common indoor pests such as ants, cockroaches and spiders.
