Flies have something new on their menu.

Increased resistance in house flies^1-2 means some fly baits are not as effective as they once were. However, Zyrox^® fly granular bait from Syngenta Professional Pest Management features a novel active ingredient that can help overcome resistance issues to effectively control house flies in urban, rural and commercial markets.

An innovative tool for resistance management

Zyrox contains cyantraniliprole, a unique active ingredient with no documented resistance. The proprietary bait matrix is highly attractive to flies, even without a pheromone lure. This makes Zyrox an ideal rotational partner in Integrated Pest Management (IPM) and Insect Resistance Management (IRM) programs for effective fly control.

Resourceful use of bait

The bait matrix of Zyrox also has a lower bulk density than most other competitor fly baits. This allows for comparable surface area coverage and volume to other baits, but with fewer pounds of bait to carry, move and store. The typical use rate is 3.2 ounces per 1,000 square feet, and the high rate of 6.4 ounces per 1,000 square feet is recommended for high-level fly infestations.

Zyrox® Fly Granular Bait, 0.85 oz (24 g)

Maxforce® Granular Fly Bait/QuickBayt® Fly Bait, 1.3 oz (36 g)

Golden Malrin® Fly Bait, 1.8 oz (52 g)

One pound of Zyrox can fill a bait station 19 times, versus one pound of the above competitor products that would fill a bait station 13 times or less.

Flexible application for maximum control

Zyrox is labeled for use in the most common areas where high fly densities result in customer complaints, such as around the following areas:

• Indoors (when used in a bait station)
• Outdoors in areas used for storing waste in refuse dumpsters that are fenced in or inaccessible to children and pets, such as restaurants, grocery stores and warehouses
• Outdoor areas of commercial operations, such as dairy, meat and poultry processing plants
• Production animal accounts, such as livestock housing structures

Through advanced scientific research and industry expertise, Zyrox is another example of how Syngenta can help Pest Management Professionals (PMPs) provide their customers a life free from the nuisance of house flies.
