I was wondering about chemical usage. I have recently purchased demand and termidor. Termidor for outside use around the foundation and Demand for inside use and outside used around windows and roof peaks and around doors. Is this the way these chemicals should be used or could I use Termidor for all of my spraying on the outside of the house structure? I am trying to control ants and carpenter ants and also waterbug roaches. I have also bought the Carpenter ant package #1 and Drione powder for where I know that I have seen a nest in the yard.
You should use the Termidor SC all around the immediate exterior of your home, 1-2 ft up the foundation and 1-2 ft out onto the ground, around door frames, window frames, places where cables, pipes or wires go through the wall and any other crack or crevice where the ants can gain entry into your home. Do not spray Demand in the same exact area where you have applied the Termidor SC or you will make the Termidor Sc less effective. You can use the Demand SC in the indoor locations you mentioned.
