I used to work at a Petland, so I know what you are going thru. They restricted our budget pretty heavily there too. Heres what I did with what I had to go on. I used gloves to handle, soaked everyone, and sprayed with De Flea Reptile Relief according to package instructions. I then cleaned the cage out completely, put paper towels at the bottom and gave them their hide. I put a very large crock with water and an airstone attached to an airpump in there with them (demand that this water is changed several times a day). Soaking and treating with De Flea every few days had them gone in a week. Hope this helps you its an unfair situation they are putting you in. I worked for a Petco many years ago, in 2000, as the fish and reptile lead. I barely ever talk about the experience because it was so unpleasant. They wouldn't let us treat anything, we basically had to put animals in a back room and let them die. Needless to say, I didn't stay with the company long, and hopefully yours is much better. Good luck!
