Extra Strong Refills for automatic insect control – powerful protection against flies and mosquitoes

When standard insect protection is no longer enough, our Extra Strong Refills provide the power you need. Designed for environments with a high presence of flies, mosquitoes, and other flying insects, these refills deliver consistent, long-lasting protection. Whether for professional use in food service, agriculture, or demanding home environments, these refills help create a space free from buzzing and biting pests.

Why Choose Extra Strong Refills?

Each refill contains a high concentration of natural pyrethrum, extracted from chrysanthemum flowers, a plant known for its powerful insect-repellent properties. Enhanced with piperonyl butoxide, the formula works by disabling the insects' nervous systems quickly and effectively—without allowing them to build resistance. It’s nature and science combined for unbeatable effectiveness.

Perfect for Demanding Conditions

The Extra Strong Refills are specifically designed for use in automatic aerosol dispensers. These devices release a fine mist at intervals you set, creating a continuous invisible barrier against flying insects. Ideal for:

• Restaurants, cafés, and bars
• Shops with open doors or outdoor seating
• Horse stables, barns, and livestock areas
• Homes with frequent insect problems
• Camping sites, cabins, and garden sheds

Up to 30 Days of Non-Stop Protection

Each refill delivers approximately 3000 sprays — enough for 30 days of round-the-clock insect control (based on a 15-minute spray interval). The ultra-fine mist spreads efficiently without leaving any residue, making it safe for everyday use in kitchens, living rooms, and around pets (when used as directed).

Key Benefits:

• Maximum strength protection with natural pyrethrum
• Safe for indoor use – no harmful propellants
• Effective knock-down and repellent action
• Tested and registered under EU standards (BAuA N-98994)
• Designed for effortless use with automatic dispensers

Which Refill Is Right for You?

If you’re dealing with light to moderate insect presence at home or in the office, our Regular Refills are a great choice. But when you're facing high levels of insect activity or large, open areas, Extra Strong is the way to go. It's the preferred option for demanding conditions in professional and agricultural environments.
