Wilco Zinc AG Gopher Bait

The product is a restricted use pesticide so you will need a special applicator's license to even purchase the bait and use it. 

Wilco Zinc AG Gopher Bait, manufactured by Wilco, treats various areas for gophers and other rodents.

The bait is placed directly into the gopher burrow, where they will ingest it. After the Wilco Zinc AG Gopher Bait is ingested, it creates a toxic gas, causing the rodent to die within a few hours.

Wilco Zinc AG Gopher Bait keeps gophers and other rodents from destroying property.

Tools Needed

A metal rod or a gopher bait injector is needed to find gopher burrows and apply the bait. A trail builder machine is also needed to apply Wilco Zinc Phosphide Gopher Bait to vineyards or orchards.

It is recommended that hand baiting be used to bait areas such as the base of trees, the opening of holes leading to caves, or on surface trails. 

How to Use

• Step 1: First, identify the targeted rodent and where they are located, as there are different rates and methods of application depending on the rodent and location. You should also calculate the size of the area you wish to treat to determine how much bait you will need. Find the square footage by measuring the treatment area's length and width in feet, then multiply them together (length X width = square footage). For acreage, divide the square footage by one acre (square footage / 43,560 sq. ft. = acres). Refer to the product label for specific application rates and restrictions.
• Step 2: Runways can be located with the help of a gopher probe, metal rod, or a stick. Using the tool, probe the ground 10 to 15 inches away from gopher mounds that are fan-shaped. If your probe sinks into the ground easily without resistance, you have found the runway. 
• Step 3: When treating for gophers, apply the Wilco Zinc Phosphide Gopher Bait by hand at a rate of 4 grams in each main runway that you are able to locate using a long-handled spoon or mechanical probe. Apply two to five bait placements per burrow system then cover the opening with dirt to block sunlight. One pound of bait can treat 1 to 8 acres depending on the number of gopher burrow systems present.
• Step 4: For ground squirrel control on lawns, ornamentals, golf courses and parks, you should prebait with untreated steamed, crimped oats by placing a teaspoon or 4 grams around each active runway or burrow opening. Wait 2 or 3 days and then bait with the Wilco Zinc Phosphide Gopher Bait. Place the bait in tamper-proof bait stations if children, pets or unintended targets might access the bait.

Where to Use

For California Ground Squirrels, the bait can be used in lawns, ornamentals, golf courses, parks, and nurseries. This product cannot be used around residential areas or areas where endangered species are inhabiting. When using Wilco Zinc Phosphide Gopher Bait as a broadcast application, it must be applied to areas with thick vegetation and grass. Bait must not be applied on roads, over water or where plants are grown for food or feed.
