Buying Guide
What to consider when selecting a gel bait for German roaches:
- Target species and spread: Choose gels labeled for German roaches and capable of transfers to others to combat colonies.
- Indoor suitability: Look for products designed for kitchens, bathrooms, and other high-traffic areas with user-friendly application.
- Active ingredient and safety: Consider the active ingredient (for example indoxacarb or fipronil) and follow label directions to minimize exposure near food and pets.
- Application method: Preference for syringes or pre-loaded tubes that allow precise placement in cracks, under sinks, and behind appliances.
- Longevity and coverage: Longer-lasting gels reduce reapplication frequency but may require reintroduction in areas with heavy activity.
