I was told that the plastic bags(the generic 'THANKYOU' ones you get at the grocery store) were as close to a humane trap as you could get for snakes, as the noise would alert you. The snake, lacking ears, would have no reason to find the noise alarming. Supposedly. It's generally around 90ish degrees in this building in the summer, and we have no AC. The humidity's pretty bad too, so I'm honestly not sure what the appeal of a heat lamp would be for her in this weather. I have also been told to put her tank on the floor where she can find it(it's on top of a dresser) or leave a heat pad laying around to draw her in. I'll put some flour down instead of baby powder, I didn't know about the smell thing. She got out because I forgot to put the clips back on her lid after putting her back and going to bed, I don't think she's strong enough yet to break the clip on her own. She's barely a year old, and small at that. The heaters we have are crusty radiators which are secured to a wall, and have to be taken apart to be serviced.
I don't mean to sound like I'm shooting down suggestions on the pretense that I know better(I know very little and need help). I'm not very good at wording things.
I'll check the crawlspace as well as I can. I can only fit my arm and shoulder down the hole, so I'd need to rip out the bathtub and part of the wall if she's stuck down there.
Also, if I suspect she's in a room I can't search easily, would making the room excessively cold herd her out of it? My brother's room is across the hall. None of the lights work and the floor is splattered with urine. She's got shed skin stuck over her eyecaps, and I'd hate to force her to navigate something even my deadened nose has trouble with.
I really, really appreciate the help. Thank you.
