HB 1431 New Hampshire House · 2026 Regular Session

restricting the use of neonicotinoid pesticides.

HB 1431 restricts the use of neonicotinoid pesticides (containing ingredients like imidacloprid and clothianidin) in New Hampshire. It bans non-agricultural applications (e.g., for lawns, gardens, or ornamental plants) and requires these pesticides to be sold only to licensed dealers and used by state-certified applicators. The bill also prohibits their use on state property (like parks and highways) except for invasive species control, structural pest management, or approved exceptions, and bans applications during bloom periods on flowering plants to protect pollinators. Additionally, the Department of Agriculture must create an educational program about pollinator-friendly alternatives and integrated pest management. The law takes effect January 1, 2027.

Introduced As Amended by the House · 7 edits
MODERATE
The House amendment fundamentally shifts the bill from a direct statutory ban with criminal penalties to a rulemaking framework giving the pesticide control board broad discretion. The original mandated reclassification, banned non-agricultural use outright, and imposed misdemeanor/felony penalties; the amended version instead authorizes the board to adopt rules that 'may' restrict or authorize various uses, adds numerous specific exemptions (indoor use, livestock treatment, research, greenhouses, orchards), removes all penalty provisions, and eliminates the education program requirement.
Scope change
The bill's scope narrowed significantly. The original imposed a broad statutory ban on non-agricultural use with criminal penalties and an education mandate. The amended version gives the pesticide control board rulemaking authority to decide what restrictions apply, carves out many specific exemptions for common uses (indoor pest control, animal treatments, research, greenhouses, orchards), and removes all enforcement penalties.
SCOPE

The bill changed from directly mandating that the department of agriculture reclassify neonicotinoids as restricted-use pesticides and ban non-agricultural use, to authorizing the pesticide control board to adopt rules that 'may' restrict or authorize various uses. This shifts enforcement from a fixed statutory prohibition to discretionary rulemaking.

The entire education program requirement (section 430:62) was removed. The original required the department to develop a public education program about impacts on pollinators, alternatives, integrated pest management, and habitat establishment.

ENFORCEMENT

All penalty provisions were removed: the original included misdemeanor/felony criminal penalties for violations, civil forfeiture up to $5,000 per violation, and administrative fines up to $1,000. None of these remain in the amended version.

ELIGIBILITY

Multiple new exemptions were added for specific uses: flea/tick/heartworm treatment in animals, lice and bedbug control indoors, indoor applications with no pollinator exposure, wood preservation and foundation treatments, invasive species management, academic/governmental/scientific research, aquarium use, enclosed greenhouses, and fruit tree orchards (with conditions including IPM documentation and application outside bloom periods).

DEFINITION

A new definition for 'structural pest control' was added, covering wood preservative applications within enclosed structures, remedial treatments, foundation treatments, and limited exterior perimeter applications within 5 feet of a building's foundation when performed by a certified applicator.

REQUIREMENT

The state property ban (section 430:61) was changed from a direct statutory prohibition to something the pesticide control board 'may determine.' Additionally, new conditions were added to the exemption process requiring documentation that integrated pest management failed, application outside bloom periods, and compliance with recommended usage for aerial applications.

A new requirement was added for the pesticide control board to devise a plan to notify registered apiaries (beekeepers) when neonicotinoid pesticides will be applied in areas that may affect their hives.
