Bayer Temprid FX Insecticide — 400 ml Monodose, Dual-Active Fast Knockdown & Long Residual

Temprid FX is a ready-to-mix, dual-active insecticide from Bayer that delivers fast knockdown plus extended residual control against more than 50 indoor and outdoor pest species.

Designed for professional pest management and serious DIY use, this 400 ml monodose bottle contains a co-milled combination of imidacloprid and beta-cyfluthrin formulated to tackle hard-to-kill pests such as bed bugs, scorpions and spiders while offering flexible label directions for interior, perimeter and foliar treatments. The single-dose packaging gives you the exact quantity to mix with one gallon of water for consistent, reliable applications without measuring errors.

How does Temprid FX deliver both quick knockdown and long-lasting control?

The product combines two active ingredients that work together: one provides fast contact activity to rapidly incapacitate pests, while the other offers residual, systemic activity to keep treated areas protected longer. That co-milled pairing improves performance against resistant or difficult species by exposing pests to different modes of action simultaneously.

• Active ingredients: Imidacloprid 21% and Beta-cyfluthrin 10.5%.
• Co-milled dual-active formula for immediate and residual effects.
• Proven to reduce callbacks in professional studies.

Where can I safely use Temprid FX around the home or business?

Temprid FX is labeled for both indoor and outdoor applications, including perimeter treatments, cracks and crevices, and foliar applications on non-blooming plants. Always follow label directions for specific sites, mixing, and safety precautions to ensure correct and legal use.

• Indoor: baseboards, voids, cracks, and around water pipes (per label).
• Outdoor: foundations, perimeter barriers, and landscape foliage (non-blooming plants).
• Not for use on blooming plants or where pollinator exposure may occur.

Which pests does Temprid FX control and how reliable is it on tough species?

Temprid FX is formulated to control more than 50 pests across indoor, outdoor/perimeter, and wood-infesting categories. It’s commonly used against species known to be difficult, including bed bugs, scorpions, and some wood-boring insects, and is a practical choice when resistance management matters.

• Indoor pests include ants, bedbugs, cockroaches, spiders, silverfish and carpet beetles.
• Perimeter/outdoor pests include fleas, ticks, mosquitoes, scorpions, hornets and ants.
• Wood-infesting targets include carpenter ants, carpenter bees, drywood termites and wood-boring beetles.

How do I prepare and apply the single-dose 400 ml bottle?

The 400 ml monodose container is intended to be mixed with one gallon (approximately 3.8 liters) of water to create a ready-to-apply spray. This eliminates measuring mistakes and simplifies job-site mixing while ensuring the correct label rate for general applications.

• Open the monodose and pour into one gallon of water; mix thoroughly before use.
• Apply using a hand or low-pressure sprayer following label application rates and site-specific directions.
• Wear recommended PPE, avoid treating blooming plants, and comply with re-entry intervals on the label.
