Unfortunately Lyme Disease is everywhere in CT as well as other nasty tick borne illnesses. You just have to use common sense and be very diligent. Our animals pick up ticks in our back yard in the grass. You don't necessarily have to be out in the woods. I have had several friends who have suffered from Lyme Disease as well as other tick illnesses and I am happy to say they have recovered. My dog had Lyme Disease, we caught it early on when she started whining whenever we touched her. We brought her right to the vet, started her on antibiotics and within a couple of weeks she was right as rain.
We check our kids and animals daily and use frontline year round. Our kids know to stay away from our animals (3 dogs and 2 cats) for 24 hours after application and then they are fine. We still find ticks on the animals but they are usually dead or have just crawled onto them and are right on the surface. The cats pick them off and leave them in our house, so we have found them inside as well.
The teeny deer ticks are the ones you have to worry about. An infected deer tick has to have been feeding on its host for 24 hours in order to transmit the disease, so you just need to be diligent about tick checks. I taught my kids how to check themselves for ticks when they were only five.
Mosquitos are another problem in this area of the country. They can carry and transmit West Nile Virus and Eastern Equine Encephalitis. Many towns test for it early on in the year and some towns will even spray to prevent an outbreak. Again, you have to use common sense, don't go out when mosquitos are most active, early morning and at dusk. Wear bug spray. Spray on bug spray with Deet (I spray Deet bug spray on my kids clothes, not on their skin) and love your bats by installing bat houses. They eat mosquitos by the thousands.
I always say you can't live in a bubble but you have to be safer than we were when we were kids.
