What the Mercer County firms do

25 businesses holding an NJDEP Pesticide Applicator Business licence are based in Mercer County (licence list retrieved 2026-11-04). 21 of them are licensed for general and household pest control (category 7A), 14 for termites and other wood-destroying pests (7B), 11 for mosquito control (8B), 10 for integrated pest management in schools (13).

7 of the 25 publish a website we could read, and what follows is taken from those sites (matched through Google Maps, 2026-11-05). 7 offer a free inspection or estimate; 5 recurring service plans; 2 a stated termite warranty or renewable bond; 1 bed bug heat treatment; 2 wildlife removal; 5 low-toxicity or eco options; 3 same-day service. None of them advertises emergency or 24-hour service on its site.

7 also serve commercial customers; 4 say on the site that their technicians are licensed, which the state list above confirms for the business; wildlife trapping is governed by NJ Fish and Wildlife rules rather than the pesticide licence, so ask the firms offering it how they handle that. Anything a site did not state is left blank below rather than guessed.

On Google Maps (retrieved 2026-11-05), the 9 firms we matched carry between 9 and 2,043 reviews each (median 490). Review counts tell you how often a firm is used, not how well; the licence list and the service table are what this page is for.
