A Natural Rodent Deterrent?

I don't want to kill this cute little guy.  But I'd rather he wasn't in our house.

So how can we tell him to stay away without using poisons or traps?

A study published in the Scientific World Journal researched the effect of Eucalyptus oil on deterring rats. They found that a 5% solution significantly deterred rats when applied daily, but did not significantly deter them when applied weekly.

A 20% solution significantly deterred rats when applied daily or weekly:



I mixed a 33% solution (1 part Eucalyptus oil with 2 parts water), and am going to start spraying it around the house weekly.  I'll report back about how this works.
