Toxic bait dispenser for applying baits for ground dwelling animals don’t seem to be professionally manufactured. Fortunately, you can build your own homemade bait dispenser with some simple tools and materials.
The following homemade bait dispenser is made of 1/4-inch rod (about 30 inches), a washer, split rivet, and an end section of 1-inch copper pipe. Bend the rod to form a handle on one end, then flatten the other end and drill a hole through it to take the split rivet.

Drill a hole through a section of pipe and use the washer on the inside of the pipe. Measure the volume of the pipe section with water against a standard measurement (be it teaspoon or tablespoon, depending on the toxicant you plan on using. Grind or cut the pipe to match the needed volume.
It’s a great way to dispense bait around burrows of ground dwelling animals. Just be sure to ONLY use the device for toxicants.
