It is permissible to kill anything that is harmful.

In multiple rooms of our house, ants are entering from the garden,& get on the food,the ground,the tables,the beds… Removing them (without killing them) from the food & environment,& verifying that we are not killing them by stepping/sitting on them or killing them inadvertently causes us some hardship. Can we kill them by using insecticides in the garden?
