Will they die if they craw over it or if they eat it?
Talstar Granules are not labeled for roach control. This is because the granules will settle at the base of the grass and then after they are watered in, will be even deeper in the soil which will minimize the chance that the roaches will contact the treated areas. You may want to consider using the liquid concentrate Talstar P so you will have better coverage to kill the roaches. The liquid will be on top of the grass and at the base to help control the roaches. The liquid can be used on and in your home as well.
