Fast Free Shipping!

Gentrol IGR is designed to interrupt the life cycle of a variety of insects, including cockroaches, drain and fruit flies, bed bugs and stored product insects. The active ingredient, Hydroprene, breaks the life cycle by preventing pest larvae from maturing to breeding adults, which prevents infestations in the future. Gentrol IGR has the penetration power to travel deep into wall cavities, cracks, and crevices reaching areas that other treatments might miss. This product has a long residual and continues interrupting the life cycle for up to 4 months. It is approved for use in food handling establishments and allows professionals the flexibility for application across multiple sites. This product is not designed to kill insects, it is designed to prevent them from reproducing.

Product Features:

  • Juvenile hormone mimic prevents normal development, breaking the insects’ life cycles.
  • Gentrol IGR translocates deep into wall cavities, cracks and crevices.
  • Approved for use in restaurant pest control, and treatments in other food handling establishments.

Product Information:

Gentrol is a non-repellant Insect Growth Regulator.  It disrupts the normal development of the immature life stages of cockroaches, drain flies, fruit flies, bedbugs, and stored product pests. Cockroaches and bedbugs exposed to the Gentrol IGR will become adults incapable of reproducing.  Gentrol also disrupts the normal life cycle of stored product pests, drain and fruit flies, and fleas; thus killing these insects during the pupal stage. In both cases, the cycle of an infestation ends.

Mixing Instructions:

Spray Mixing:

Mix Gentrol with diluent and apply with spray or hand application equipment, such as hand-pressurized or power-operated sprayers capable of delivering general surface spray, fogging (space spray/mist), spot, crack and crevice spray applications, or with a paint brush, roller, or similar device.

Use 1 ounce of Gentrol to 1 gallon of diluent. Partially fill the mixing container with diluent, add the Gentrol, shake or stir, and fill to final volume. Use diluted solution within 48 hours of mixing. Shake or stir before each use.

Tank Mixes:

Gentrol may be tank mixed with an adulticide currently registered for use, unless the product label prohibits such use. Use the resulting tank mixture in accordance with the more restrictive label limitations and precautions.

Application Rates:

Apply the Gentrol dilution at a rate of 1 gallon per 1500 sq ft of surface area. Use spray/application equipment capable of delivering a variable spray or coating to uniformly apply the solution. Apply to areas such as walls, floors, ceilings, attics, basements, or crawlspaces. NOTE: Prior to treating around air ducts, shut off ventilation system. Allow treatment to dry prior to turning on ventilation system.


Store in a cool area away from children.
