Buying Guide
What should I look for when choosing roach control products?
- Target pests: Prioritize products labeled for German roaches, as they have distinct behaviors and resistance patterns.
- Mode of action: Use a combination of gels and IGRs to achieve immediate knockdown and long-term suppression.
- Indoor placement: Favor gel baits in kitchens and bathrooms; use IGRs in cracks, crevices, and concealed areas.
- Space considerations: For large apartments or multi-unit buildings, consider point-source devices for continuous exposure without spraying.
- Safety: Review labeling for pet and child safety guidance; implement bait stations and gloves as needed.
How to apply effectively
Apply gel baits in thin lines or pea-sized dots in areas roaches travel, such as behind appliances, under sinks, and in cabinet corners. For IGRs, follow directions for safe space application and allow time for developmental disruption to reduce population growth.
What combination works best?
Using gel baits for immediate feeding and an IGR for long-term development control provides a balanced approach. This combination reduces rapid reinfestation and supports ongoing suppression in challenging environments.
