Gentrol IGR Concentrate – Insect Growth Regulator for Roach & Fly Control in Buildings

Gentrol IGR Concentrate travels deep into wall cavities, cracks and crevices, reaching the stored product pests that other treatments miss. Hydroprene, the active ingredient, prevents stored product pest larvae from progressing to the pupal stage of development, so the larvae die before they become breeding adults and future infestations.  If you are using Gentrol IGR as a fogging application, please note that for fogging, it is labeled for use in food handling areas and other indoor applications ONLY.   Gentrol Concentrate should never be used to eliminate a roach population by itself. * Gentrol will not kill roaches...it only prevents them from reproducing. * Use roach baits and roach sprays in conjunction with Gentrol Concentrate. For smaller areas like apartments we would recommend the Gentrol Aerosol - IGR. Gentrol IGR (Insect Growth Regulator) Concentrate travels deep into wall cavities, cracks and crevices, reaching the stored product pests, drain and fruit flies, and fleas, that other treatments miss. Hydroprene, the active ingredient, prevents pest larvae from progressing to the pupal stage of development, so the larvae die before they become breeding adults – and future infestations. Cockroaches and bedbugs exposed to Gentrol will become adults incapable of reproducing. Stored product pests encounter hydroprene the same way they encounter insecticides – traveling on or rubbing against a treated surface. Gentrol IGR Concentrate spreads out from its point of application, creating a much larger treated surface than conventional insecticides. Gentrol Concentrate should always be diluted with water when applying with a sprayer. Because Gentrol is an insect growth regulator and not an adulticide, it should not be used as the sole protection for target pests. Use Gentrol as a general surface spray, fogging, spot, or crack and crevice application. Mix Gentrol Concentrate with diluent and apply with spray or hand application equipment, such 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. Mix GENTROL IGR Concentrate with water and apply with spray or hand application equipment, such as hand pressurized or power-operated sprayers capable of delivering spot or crack and crevice spray applications. Dilution Preparation: For spot and crack and crevice preparations: Use 1 ounce of GENTROL IGR Concentrate to 1 gallon of water. Partially fill the mixing container with water, add the GENTROL IGR Concentrate, shake or stir, and fill to final volume. Use diluted solution within 48 hours of mixing. Shake or stir before each use. Spot and Crack and Crevice Applications: Apply GENTROL IGR Concentrate diluted spray solution using either a pressurized spray system capable of delivering a pinpoint or variable spray pattern or a device capable of coating evenly. Make crack and crevice applications directly to areas such as crevices, baseboards, floors, ceilings, or walls. Make spot treatments to areas such as storage areas, closets, doors, and behind and under furniture and beds. To treat bedbugs, apply to harborage points mentioned above; in addition, under beds, bottom side of box springs (do not treat linens and mattresses), under and behind night stands, to points where carpet and wall meet, cracks in cove base, molding, and other areas where bedbugs harborage. Gentrol Concentrate may be tank mixed with an adulticide currently registered for use, unless the product label prohibits such use. Gentrol Concentrate may also be converted to a foam. For best results, use the higher amount of the foaming agent rate range. Always read the product label completely before use. Each 1 oz. bottle yields 1 gallon of finished solution. Each 16 oz. bottle yields 16 gallons of finished solution. 1 gallon of finished solution covers 1,500 square feet of surface area.
