A Short Legislative History of Pesticides in Connecticut

Early 1960's – Connecticut starts licensing pesticide applicators.

1970's – Connecticut creates a list of registered pesticides in order to meet new federal guidelines.

1991 – Creates a pesticide notification law, which creates two new regulations:

  • The law requires yellow notification labels of a certain size to be placed on properties that have been treated with pesticides
  • The law establishes a Pesticide Registry managed by the CT DEEP.  The Registry requires pesticide companies to warn those people on the Registry when the abutting property is going to be sprayed. The form for the registry, available on the CT DEEP website (see below) must be submitted before December 31 of each year for the following spring.
  • Download the form to sign up for DEEP's Pesticide Registry

    • 1999 – Public Act 99-165 – establishes a school pesticide law in response to Environment and Human Health's report on Pesticide uses in Connecticut's Public Schools. The law requires that:

  • Only licensed applicators could spray in a school;
  • Parents and staff be provided with the school's pesticide program at the beginning of the school year;
  • A registry be put in place at the school for parents and staff who want to be notified before pesticides are sprayed;
  • Records of what pesticides were sprayed be kept in the school for 5 years
  • No application of pesticides be made during school hours - except in emergencies.

  • 2005 — Public Act 05-252 - Bans the use of lawn-care pesticides on public and private grammar schools' and children's daycare centers' grounds. This law took effect in January 2006. There is a 3-year exemption for grammar school athletic fields – but in that 3-year period the athletic fields must use Integrated Pest Management (IPM) methods and then after the three years is up, those fields must become organic as well. The rationale is that it takes some time to wean athletic fields from their chemical dependency and on to organic methods. The ban on lawn-care pesticides will apply to the grammar school athletic fields as of July 2008.

    2007 – Public Act No. 07-168 establishes a lawn-care pesticide ban on the grounds of public and private schools with grades K-8.  Public Act 05-252 stays in affect for Children's Day Care Centers while Public Act 07-168 supercedes Public Act for  05-252 for grades K-8.

    • Bans the use of lawn-care pesticides on public and private school grounds with grades K-8 as of October, 2007.
    • There is a two-year exemption for the athletic fields of schools K-8 - however the fields must be maintained by using Integrated Pest Management (IPM) methods. At the end of the two-year period the athletic fields must become organic as well.  The rationale being that it takes some time to wean athletic fields off of their chemical dependency and onto organic methods.

      The ban on lawn-care pesticides applies to school athletic fields with grades K-8 as of July 1, 2010.

    2009 - Public Act 09-56 bans the use of lawn-care pesticides on the grounds of children’s day care centers as of July 1, 2010
