Associate Certified Entomologist (ACE) Program

Being ACE certified can give you and your company the edge it needs to compete successfully with other pest control providers. Many public and private institutions require independent certification for their pest control contractors, and increasingly the general public is seeking expert providers for every service.

The Associate Certified Entomologist (ACE) program is offered to those with training and professional field experience in structural pest management. It's rapidly becoming the industry-standard for pest management professionals, growing at an average of 35% a year since the program's introduction.

  • Hold a current U.S. pesticide applicator's license
  • Pass a rigorous examination
  • Sign the ACE Code of Ethics
  • Maintain a minimum number of CEUs annually (upon passing the exam)

ACE-International Program

In October 2014 the Entomological Society of America (ESA) added a new dimension to the popular Associate Certified Entomologist (ACE) professional credentialing program. ACE is an individual credential earned by those who have demonstrated high levels of professional training and understanding of entomology as it relates to structural pest control. The program includes a rigorous examination that has particular emphasis on the principles and practices of Integrated Pest Management (IPM). No formal academic degree is required for earning the ACE making it a strongly desired certification for the pest management industry.

In September 2013 NPMA endorsed the ACE program and has been helping ESA promote it in the US and around the world. At PestWorld 2014 ESA launched a new international version of the ACE program. There are two primary differences between the US ACE and the international ACE.

  1. In the United States, applicants must hold a current pesticide applicator's license in at least one state.
  2. Since not all countries require similar licensure, no license is required for international applicants. However, to compensate, all international ACE applicants must take and pass a second examination that focuses on pesticides and pesticide safety.

The exams, which are developed and maintained by ESA, are delivered to applicants in a proctored setting. Most applicants take the exam with an in-person proctor, but increasingly some are making use of a service where they take the exam on their own computer while a proctor observes and monitors them via the computer's webcam.
