Vanish Pest Control and Lawn Care believes that the best defense against weeds is a healthy, dense turf grass, which is the objective behind our fertilization program. If necessary, Vanish Pest Control and Lawn Care will apply a pre-emergent herbicide, along with the fall and spring applications of fertilizer. This will control the number of weeds that can grow in your lawn. Post-emergent herbicides may also be applied on an as-needed basis.
