Gentrol Complete EC3
Gentrol Complete EC3 is a unique broad-spectrum insecticide that also functions as an insect growth regulator to eliminate pests from various developmental stages in food and non-food handling establishments.
12/15/25
Gentrol Complete EC3, manufactured by Zoecon, is a liquid broad-spectrum insecticide that provides a unique form of control of flying and products pests like cockroaches or confused flour beetles from the inside of buildings and structures.
This effective formulation provides a dual-action formula as an insect growth regulator (IGR) to disrupt pests' development stages before they reach sexual maturity and kill some pests during the pupal stage, leading to residual control of future generations.
Gentrol Complete EC3 is an easy-to-use product that lasts for up to 21 days after application, which helps to minimize the amount of indoor applications needed.
Tools Needed
As a general surface treatment, it will need to be applied with a handheld pump sprayer, backpack sprayer, power-operated application equipment, Micro-Injector, Actisol applicator, paintbrush, or other porous applicator attached to a handle.
We recommend using a handheld pump sprayer for easier control of spot applications and treatment of small areas.
How to Use
- Step 1: Determine how much Gentrol Complete EC3 to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet and multiply them together (length X width = square footage). For light applications or maintenance, apply 1.3 oz. of Gentrol Complete EC3 per gallon of water per 800 to 1,600 sq. ft. For severe infestations, mix 5.2 oz. of product per gallon of water per 800 to 1,600 sq. ft. Amount of concentrate is dependent upon pest species, infestation level, and service interval required. Refer to the label for specific application rates.
- Step 2: Fill the applicator tank halfway with water, add a measured amount of Gentrol Complete EC3, and then fill with the remaining half of the water. Close and shake before use to ensure proper mixing.
- Step 3: Treat cracks and crevices with a coarse pressure spray until wet but not to the point of run-off. Adjust the spray nozzle to a low-pressure spray for spot and general surface treatments. If needed, reapply 21 days after the first application.
