Ticks are small, flat bugs with 2-part bodies and very small heads. They are not insects, because they have 8 legs like a spider. They have no antennae and live on the blood of their hosts by burrowing their head into its flesh.
The best way to avoid a tick problem is to avoid wooded and unkempt areas. If you must venture into such areas, make sure you wear long sleeves and hats, preferably with light colors so that ticks will be easier to spot on them.
If you regularly venture into wooded areas, you will have to use your best preventative measures to avoid attracting ticks. However, if ticks are present in your own yard, a TDI specialist can treat problem areas to provide protection from these harmful insects.
