Unlike Eastern Moles star-nosed moles are found in very wet to swampy soils. The few mole trapping jobs I get for star-nosed moles usually happen in late winter to spring when water tables are high. Most of the properties I trap Star-nosed moles have a stream, brook or swampy area very close to the lawn.
Damage caused by Star-nosed moles in Connecticut
Star-nosed moles are very destructive. They tend to swim through their tunnels and make muddy mounds everywhere. These moles will make shallow runs like little creeks and will travel on the surface. Unlike with common Connecticut moles I never know how many of these I am going to catch. The damage is horrible with 5-6 inch ruts in the lawn not uncommon. Trapping is more difficult because traps are submerged under water. poisons are 100% ineffective on star-nosed moles. It is very common for me to set traps in flowing water for these moles. As interesting these little moles are they are the most destructive animal to lawns bar none in Connecticut. I have seen yards that need a to be regraded and seeded because of the destructive nature of these moles.
I am usually to Middlefield Connecticut yearly trapping star-nosed moles. Only in the wettest of years am I trapping Star-nosed moles in the summer. two places in Connecticut are the exception to this rule. One in Cheshire has an under ground stream that the moles travel and I can be trapping moles in Cheshire at anytime of the year. The other is Durham with a creak running through the property that never dries. Trapping moles in Durham also can happen anytime do to this permanent brook.
