I can't tell you if you should use anything or not but you can get fleas many different ways. They can jump something like 150 x their size and hop onto us, humans and we can bring them indoors.
I would imagine that we can do the same with ticks if we are walking thru an area where they are. I know I have gotten them on me while gardening.
Since you do not want to use chemicals, maybe you can find a natural repellent. I am both using Frontline and just started bathing them with lemon grass oil. So far I haven't seen anything on them and I live in a semi wooded area. But I also have my yard sprayed for ticks and fleas. |
