Meet the Snails of Utah: A Mosquito Squad Expert's Guide

Snails are sometimes a significant issue in Utah gardens when their populations grow uncontrolled. At Mosquito Squad, we understand the importance of managing these garden invaders. Let's take a closer look at the most common snails in Utah, their life cycles, habitats, and effective methods to control their populations.

The Most Common Snails in Utah:

1. Brown Garden Snail (Cornu aspersum):

• Life Cycle:
  • Egg Stage: Brown garden snails lay eggs in clusters in moist soil. The eggs hatch in about two weeks.
  • Juvenile Stage: Juvenile snails emerge and start feeding immediately. Their shells harden as they grow.
  • Adult Stage: These snails take 2 to 3 years to reach maturity. They become active in the spring, mate, and lay eggs throughout the warm months. They are primarily nocturnal​​​​.
• Habitat:
  • Brown garden snails thrive in gardens, particularly in moist environments. They are often found under debris, stones, and dense groundcovers where they can hide during the day​​​​.
  • Local Areas: Commonly found in Salt Lake City, Provo, and Ogden residential gardens.
• Prevalence:
  • Brown garden snails are the most common snail species in urban garden environments in Utah. They are widespread and can cause significant damage to garden plants due to their feeding habits​​​​.

2. Utah Roundmouth Snail (Valvata utahensis):

• Life Cycle:
  • Egg Stage: The Utah roundmouth snail lays one group of eggs per year in well-oxygenated areas.
  • Juvenile Stage: After about two weeks, young snails emerge and begin grazing on fine sediments and aquatic vegetation.
  • Adult Stage: This snail has a lifespan of about one year and reproduces between March and October​​​​.
• Habitat:
  • The Utah round-mouth snail typically inhabits cold-water springs, spring creeks, and the Snake River. It prefers well-oxygenated areas with fine sediments and aquatic vegetation, often in limestone or mud substrates​​.
  • Local Areas: Typically found in aquatic habitats around Logan, Bear Lake, and the Provo River.
• Prevalence:
  • The Utah roundmouth snail is less common than the brown garden snail. However, you can still find the Utah roundmouth snail in specific water habitats across Utah. These snails play an essential role in the environment. Still, they can sometimes cause problems in areas where people control the water, like reservoirs.

3. Common Woodlouse Snail (Lauria cylindracea):

• Life Cycle:
  • Egg Stage: Common woodlouse snails lay eggs in hidden spots like under stones and in leaf litter.
  • Juvenile Stage: Juveniles are small and cylindrical with brownish shells. They emerge from eggs and feed on available organic matter.
  • Adult Stage: They mature into adults with more defined, rigid shells​​.
• Habitat:
  • These snails often inhabit areas under stones, leaf litter, and gardens. They thrive in moist, shaded environments and areas rich in organic matter​​.
  • Local Areas: People commonly spot these snails in wooded areas and gardens in Park City, Heber City, and Cedar City.
• Prevalence:
  • Common woodlouse snails are widespread in various habitats across Utah, particularly in gardens and areas with abundant organic matter. They play a role in decomposing organic material but can sometimes become garden pests​​​​.

Controlling Snail Populations

Effective control of snail populations involves a combination of methods tailored to your garden's needs. Here are some strategies that we recommend:

1. Sanitation:
   • To maintain a clean garden, remove debris, stones, and dense groundcovers that shelter snails. Regular weeding and trimming reduce moist, shaded areas that snails favor​​.
2. Handpicking:
   • Removing snails during their active periods (usually at night or early morning) is highly effective. Collect and dispose of them in sealed bags or buckets of soapy water to ensure they don't return​​​​.
3. Barriers:
   • Use copper strips around garden beds to deter snails, as they avoid crawling over copper. Mesh screens and other physical barriers can protect specific plants​​​​.
4. Traps:
   • Set up traps using beer, yeast water, or inverted melon rinds to attract and drown snails. Regularly check and clean traps to maintain their effectiveness​​.
5. Natural Predators:
   • Encourage birds, toads, and beneficial insects like ground beetles to control snail populations naturally. However, be cautious, as some predators may also damage young plants​​​​.
