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

Professional-grade insect growth regulator (IGR) concentrate trusted by NYC pest control operators. Gentrol IGR Concentrate travels deep into wall cavities, cracks, and crevices where cockroaches and stored product pests breed — reaching areas that contact sprays simply cannot.

For building supers and property managers, Gentrol IGR is the long-term solution to recurring infestations. It doesn't just kill — it sterilizes insects and prevents eggs from hatching, breaking the breeding cycle that keeps roaches coming back in multi-unit residential buildings and commercial spaces.

• Controls roaches, stored product pests, drain flies, and fruit flies
• Penetrates wall voids, false ceilings, and hard-to-reach harborage areas
• 16 oz concentrate makes up to 100 gallons of finished solution
• Ideal for treating multiple apartments in a single service visit
• Combine with gel baits for a complete IPM program

One bottle goes a long way — cost-effective for supers managing pest control across an entire building.
