Gentrol IGR Concentrate

Gentrol IGR Concentrate, manufactured by Zoecon, is a high performing insect growth regulator concentrate that helps to gain control over various immature insects, such as bed bugs or cockroaches by stunting their growth for up to 120 days after application.

Features a translocative active ingredient (S)-Hydroprene 9.0%, which effectively breaks the pests life cycle by making adult insects incapable of reproducing and stunting their growth, providing more long-term pest control. Not only does it limit resistance and reinfestations situtations, but it also increases the success of other pesticides like baits.  

Gentrol IGR Concentrate alone can be used to address an insect infestation, but it can easily be mixed with another insecticide to simultaneously target adult pests. When applied this product can control insects hiding deep within cracks and crevices of multiple sensitive sites like restaurants, residential homes, or nursing homes.

Tools Needed

Apply Gentrol IGR Concentrate, as a fog or an ultra-low volume (ULV) mist with equipment such as ULV, mechanical misting sprayers, aerosol generators, or thermal foggers to achieve uniform coverage.

When Gentrol IGR Concentrate is mixed with a diluent it may be applied with a 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.

How to Use

• Step 1: Prior to Gentrol IGR Concentrate application, remove or cover all food items in area to be treated. Determine how much Gentrol IGR Concentrate you will need by measuring the square footage of the treatment area. To do this, measure the treatment areas length and width in feet then multiply them together (length X width = square footage). Use 1 oz. of Gentrol IGR Concentrate mixed in 1 gallon of water per 1,500 sq. ft. of surface area for general surface applications. For fogging (spray/mist) applications, use 1 oz. of product per 12,000 cu. ft. So for example, if you had a 3,000 sq. ft. area to treat, you would need 2 oz. of Gentrol IGR mixed with 2 gallons of water.
• Step 2: Fill your sprayer halfway with water and then add 1 ounce of Gentrol IGR Concentrate to the tank. Fill the sprayer the rest of the way with remaining half of water and then shake the sprayer. An approved adulticide can also be added, just follow the label instructions on the adulticide label for application rates.
• Step 3: Spray labeled indoor areas where targeted pests have been spotted or known to frequent. Make spot treatments along baseboards, crack and crevices, storage areas, around doors and windows and on floors and ceilings. To spray the mixed Gentrol IGR Concentrate as a fog application, apply the product in the air and direct mist toward all areas that may harbor target pests. After treatment, leave the room closed for 30 minutes or longer as recommended by the equipment manufacturer or the labels of other products applied in tank mixing. Do not remain in treated area; ventilate before reentry. If needed, reapply after 4 months after the last application or every 14 days for heavy bed bug infestations. Repeat applications at 2 to 4 week intervals depending upon the severity of drain fly or fruit fly infestation.
