CERTIFIED SPRAY APPLICATORS: All our spray applicators have attained a high level of knowledge and experience in the field of pest control through spraying. They have been certified by the Department of Environmental Conservation under the category of Ornamentals and Turf. To acheive this certification one must have at least 3 years experience applying pesticides under direct supervision of a licensed applicator, and prove their knowledge in this field by passing an intensive exam given by the D.E.C. This exam covers an array of subjects, from insect and disease identification, susceptible plants, methods of spraying, and most importantly, the necessary precautions the applicator must take when applying pesticides. With Neal's Tree Experts you are assured that only low impact, non-persistent, environmentally safe products will be used by qualified conscientious people. For those customers who are leery of conventional spraying we do offer a systemic trunk injection program that has proven very effective in disease and insect control
