Ticks will lay their eggs just about anywhere including inside of your house and outdoors. Ticks lay eggs inside of people’s houses near baseboards, on carpet, furniture, or rugs. In addition, they will also lay their eggs outside of your house typically on soil, leaves, or branches. Ticks lay thousands of eggs at a time typically in the spring timeframe after they have reached a two-year maturity. A common misconception is that ticks lay eggs where they attach to their host. Ticks have to detach from a host in order to lay their eggs so you should never find tick eggs on your dog.
