Leave it the big brother

Leave it to my big brother.  He recently moved in with my mom and she isn’t handling the situation very well.  She just called me all upset about him not sealing the dog food properly, and a few other things in the pantry area and now she has problem with moths.  I sent her an email with a link to moth traps that she can purchase and use that is safe around her other food items.  She had to throw away a lot of stuff that was in her pantry, not to mention the huge bag of dog food.  Her budget is very tight and I told her that she needs to make my brother pay for the loss of stuff plus ordering those traps.  She asked if my hubby and I would order them and I told her no.  Why should we have to pay for something he did?  I don’t mind helping her or sending her some money for groceries, but let my brother clean up his own mess!!
