How would you handle mum's recovery and infestation?

[naturesbuds]

I’m feeling really stuck and would appreciate some advice.
My mum recently had a bad fall and has fractured her shoulder, so she’s very vulnerable at the moment and struggling. She lives with my sister (who isn’t working), and unfortunately the house now has a cockroach infestation which is honestly awful.
I stepped in and arranged pest control and paid a £100 deposit to get things started, but there doesn’t seem to be any proper plan and nothing much is happening. My sister isn’t really pushing it forward or taking charge of sorting it, and I feel like it’s all being left hanging as she is'nt working currently
The problem is I’m already stretched financially with my own commitments and I can’t keep funding this or chasing everything myself. At the same time, I feel terrible because my mum shouldn’t be living like this, especially in her condition.
I also feel awkward raising it properly with my sister as I don’t want to cause a big fallout, but doing nothing isn’t an option either.
WWYD in this situation?
How do I handle the money side of it without it turning into a big argument?
I just want my mum somewhere clean and safe while she recovers, and right now it feels like I’m the only one trying to make that happen.
Thanks for any advice

Aw you are so caring. Any postulate can stay at yours for a bit so you can keep an eye on her? If not you’ll have to risk a fall out with your sister, stressing the urgency and mum’s Health xx good luck

If your sister isn’t working, I doubt she can afford it either.

Is it your sister's house or your mum's house? I think asking your sister who's not working to pay for it is a bit pointless as she probably doesn't have the money. Would your mum be willing to pay? I would have a serious conversation with your sister and say that your mum needs a clean hygienic home to recover in and that the cockroach infestation needs to be addressed urgently. Would your mum be able to stay with you until it's sorted out?

Hi Endof year, you're right that my sister's not working, expecting her to pay to sort it probably isn’t realistic.
I will need to approach her though that your mum needs a clean, safe place to recover and that a cockroach infestation really isn’t acceptable, especially health‑wise. It does need dealing with properly and urgently.
And absolutley my mum can stay with me until it’s sorted. At least then she’ll be somewhere clean and comfortable while everything gets dealt with. Thanks for advise
