ZOECON Gentrol Point Source IGR Discs, 20-Pack — 90-Day Hydroprene Control, 75 sq ft Coverage

ZOECON Gentrol Point Source is an adhesive, non-spray insect growth regulator device that provides up to 90 days of control against roaches and stored-product pests by releasing hydroprene across a treated surface.

Gentrol Point Source uses the insect growth regulator hydroprene in a compact, tamper-resistant disc that releases active ingredient to a filter paper when activated, protecting up to 75 square feet per disc. Because it works by disrupting pest development rather than by knockdown toxicity, exposed immature pests fail to reach reproductive adulthood. The product arrives in a box of 20 adhesive-backed units and is designed for use where sprays are undesirable, such as food handling areas, healthcare facilities, and other sensitive environments.

How do I activate and place Gentrol Point Source for best results?

Activation is simple: squeeze the raised end of the plastic disc so the internal capsule releases the IGR onto the attached filter paper. After activation, stick the device in a dry, protected location near harborage sites or food storage, avoiding direct contact with water or cleaning solutions.

• Peel backing, squeeze the raised end to release hydroprene onto the filter paper.
• Affix to vertical or horizontal surfaces within 75 sq. ft. of the target area.
• Place near cracks, crevices, equipment feet, or storage shelving—out of routine contact.
• Do not place where it will be regularly wiped or exposed to liquids.

What pests does this IGR target and how soon will I see effects?

Gentrol Point Source targets immature stages of roaches and various stored-product pests by interrupting their development so they cannot mature and reproduce. Initial effects are often visible within one to two weeks as malformed adults with reduced fecundity; population reductions become more noticeable over weeks as the life cycle is interrupted.

• Active ingredient: hydroprene (IGR), works on pre-adult stages.
• Effective against German cockroaches, other roach species, and stored-product insects.
• First signs: crinkled wings or nonviable adults in 7–14 days.
• Full population suppression requires continuous monitoring and integrated tactics.

Can I use Gentrol Point Source in food handling or healthcare facilities?

Yes—this non-spray formulation was designed for areas where aerosols and surface sprays are restricted, such as kitchens, food processing zones, nursing homes, and hospitals. Because the disc adheres and passes IGR to a filter paper, there is no need to evacuate occupants during placement, but follow facility SOPs for pest control devices and food safety requirements.

• Suitable for food handling establishments when placed per label and away from direct food contact.
• Useful in patient-care areas where minimal disruption is required.
• Low toxicity profile; still follow local regulatory and facility rules.
• Replace or reapply discs every three months for continuous protection.

How long does one disc protect an area and what maintenance is needed?

Each activated disc treats approximately 75 square feet and provides about 90 days of IGR release under normal indoor conditions. Check placements regularly to ensure devices remain adhered and free from wiping, spills, or heavy dust; reapply new discs on the three-month schedule or sooner if disturbed.

• One disc covers up to 75 sq. ft.; plan spacing accordingly for larger rooms.
• Intended release duration: roughly 90 days per disc.
• Replace discs quarterly or whenever the device is dislodged or contaminated.
• Batch numbers on discs indicate production lot, not expiration date—store per label instructions.

Who is this for: ZOECON Gentrol Point Source is suited to pest management professionals and facility managers who need a discreet, non-spray IGR option for roach and stored-product pest suppression. It is especially useful in food service, food processing, healthcare, and other sensitive accounts where aerosols or broadcast sprays are unacceptable. Use it as part of an integrated pest management plan—combine monitoring, sanitation, and targeted baits or traps to achieve the best long-term results.
