flea infestation continues

so stressed past week with the flea infestation. i’m starting to lose myself. the flea obsession has fully taken over my psyche and seeped into my dreams resulting in nightmares. we’ve bug bombed the rooms, the trailer my brother is staying in, had a guy coke and spray the back porch and the front yard, bug bombed the room jake was always in twice. found another flea on my guinea pig even after treating them with flea medication a second time in a week which is not recommended. still, they’re scratching like crazy and when i picked up my guinea pig to examine her then put her down i saw it again. idk if it’s the same big flea or a different big flea. but i’m sick of this. i found a live one in the cage that i smacked and a dead one. i picked her up again and took a flea comb trying to find it but i couldn’t seem to find that flea again. i tried combing my other pig but she wasn’t having it and she’s much harder to hold and deal with cuz she’s a big gal. my hamster started to act weird too so i watched her a bit and noticed her wobbly behavior and constant scratching. so the next day i went out and bought new hamster bedding as it was time to change it and i saw a flea on top of the bedding in her cage as well. so i’m freaking out. i sanitized and hardcore cleaned the cage as i didn’t with the guinea pig cage. i checked my hamster a little bit today but didn’t see anything idk. some of the fleas are so small and fast. Mr Dabs was treated with medication as well. i combed him yesterday and found a flea on him but today i combed him and didn’t see any. they HAVE to be somewhat dying cuz of the medication. this infestation is so out of hand and it’s so scary because they multiply so fast with so many. i’ve cleaned and everything. my bf won’t pay for the house to be sprayed cuz it’s so expensive but i’m starting to lose hope here. i started to set out some traps i set tonight. on youtube i saw a guy out soap and water in dishes and leave them around the house for 24 hours. so i’m trying that. i need a lamp tho to generate heat and i only have 2 lamps and 1 doesn’t get very warm idk. idk what to do but i’m worried about my pets. i’m gonna comb the guinea pigs every night and hope they go away and the flea medicine is gonna continue time work… unless it’s not at all idk
