Effective method of mole control?

• A. Ultrasonic devices.
• B. Chemical fumigants.
• C. Water drainage.
• D. Traps are the most effective.

Answer: (D)

The most effective way to reduce mole activity in turf is to trap them. Trapping directly removes individuals from the population, and moles live in discrete, recognizable tunnel systems. By locating active runs—often indicated by fresh soil mounds or recent tunnel activity—and placing traps in those runs, you can achieve reliable captures and a noticeable drop in damage. This direct approach works quickly and can be repeated across the affected area to cover multiple active territories.

Ultrasonic devices rely on sound or vibration to repel pests, but signals don’t reliably reach or influence moles beneath ground, and field results are inconsistent. Chemical fumigants require properly sealed, deeply buried tunnels and careful handling; in lawn settings, they’re often impractical, hazardous, and rarely provide complete or cost-effective control. Simply improving drainage targets habitat quality rather than directly reducing the mole population, so while it may lessen activity somewhat, it doesn’t reliably stop damage on its own.

So, trapping stands out as the best option because it directly lowers the mole numbers with proven effectiveness when set in active runs.
