i also have my dog in my apartment so when it shows 90 degrees or close to it on the thermostat i have to take precautions so my dog and me dont end up getting sick cause of the high temperatures and thats why i am using my air conditioner as i will just keep it on till the thermostat goes down to 70 degrees or so and then turn off conditioner and just use my windows and my ceiling fan till i have to use the air conditioner again!Also I do not own a heat lamp so i just make do with what i have!The species i do have are 2 gemmatus creobroter females and a male and 8 gemmatus spotted eye flower mantus nymphs and one chinese mantis ooth and a religiosa mantis ooth!But i think those 2 species can handle temps down to 60 degrees at least and thats what i have had before with no problems!
