We have rental three times in Australia and each time we have had a pet so we have had to pay the $100 pet bond. The previous 2 times we moved out they did not pay the pet bond back and we were not asked to fumigate for flees. Now this time we have received a letter from the agency that they want proof we have fumigated inside and outside the house for flees. I thought this was what the pet bond was for. ?
