My mom (88) is in diapers 24/7. What can I do to contain the odor once in the trash? We put them in trash bags, but it's not helping.

I bought a flip top small trash can. I lined it with a trash bag. When I took the Depends pull up off I rolled it up and placed in the trash can.* If I could, I would get as much #2 off of it as I could. I too put wipes in there. I folded them with dirty side in. I had an airfresher, those stick ups, inside the lid. When full, which does not take long, I put in outside trash. I then sprayed Lysol in trash can and lined it again. A bowl of vinegar will help absorb some of the smell. I had a diaper Genie for my daughter. Loved it.

* when using tabs, you can easily roll the diaper and use a tab to keep it closed. I think we used to fold the top down and then roll it and use a tab to secure.

I always tied the diaper, gloves, and anything else associated with a clean up in a plastic bag. Then kept a covered garbage can outside that was lined with a large garbage bag. That one was only for diapers and clean up associated with them.
When the garbage got put out for pick up at whatever house I was working at, I'd just tie up the garbage bag with the bagged diapers in it and put it out with the main one.
The smell stayed pretty well contained doing it this way. Even in the summer. If you put the diapers outside immediately it will greatly reduce the smell in the house too.

air wick V.I.P spray. Could be that it's an oil based one,but it can trap the smell well.
I use it at work for the trashbin the briefs are put in during rounds, and it handles well.
So spray the actual bin first, put in an empty bag, spray that as well.
If there's not a lid, get a bin with a lid, and spray the lid too.

Since you're at home I'd say to get small bags (best found in pet sections, they're usually scented) and when throwing the brief away,put it in a small bag and tie it up before putting it in the main bin.

My husband had been in diapers years also so I buy Sam’s gal zipper lock bags for poppy ones you can get a diaper genie like used fir baby’s for wet ones . I just couldn’t wrap them in gravely bags any longer I felt bad for the sanitary disposal men. Bless their hearts . It’s well worth it and you can fit two in one bag the slip your gloves in there also . I’ll give up anything else I have to , and continue buying them you get 4 big boxes at a times . Or try the dollar store. This has really helped me I couldn’t take the smell
any longer my garbage can was like an out house . Good luck

Check for a urinary tract infection. My mom’s urine was particularly pungent when she had a UTI.

I use Odoban from Home Depot for a deodorizer and clean up on floors. It has really helped. I go through a ton of plastic grocery bags because I replace the garbage with every Depends change.

I would put them outside if the odor can not be contained by sealing it in a trash bag.

I would also talk to her doctor about the strong odor, this can be a sign of kidney issues.

I had a smaller garbage can that the soiled briefs, wipes, gloves and other items used for a change would go into. That would be taken out several times a day to the garbage can outdoors. I used an enzyme odor absorbing product to spray in the air and in the can. I would then put another bag into the garbage can.
Taking the bags out as often as you can is the best way to eliminate odors. Washing laundry as soon as possible will help as well. I used one of two products, sometimes both. Clorox Urine Remover and Odor Ban. The mattress would get wiped down as well when I got my Husband up and before (obviously) I made the bed again.
There are garbage cans that are used for child's diapers that will seal each diaper in so that no odor escapes. (Think of it as sausage links with a soiled brief or diaper in each casing) Not sure how long that takes to breakdown in a landfill!
But it is effective.
Obviously a wet brief will not have the odor that one with fecal matter will. Get fecal soiled briefs out ASAP to eliminate odors.
And a diluted spray bottle of Odor Ban is a great think to have on hand! (I diluted it to "sanitizer" strength as the bottle directs so that I could use it anywhere. Not just for odors...I still use it to do my floors in my steam mop)

Okay. Three things to check.

1. Regulations usually state that used continence products should be double-bagged and then placed with household waste. Are you double-bagging them?

2. Are you unusually sensitive to odours?

If 1 = yes and 2 = no, then...

3. Up your mother's water intake, get her urine checked for possible infections, and change her pad more frequently.
