Garbage stuck in my back yard in sims 2, help!

There is a pile of garbage in my back yard in Sims 2. My sims will not clean it up and neither a butler or maid will either. It's attracting bugs and making my dog sick and I can't figure out how to get rid of it. I have had glitches like this before...

with kids toys and once a chair but this is really annoying. I have built a wall around it just so my dog won't play in it anymore but that didn't solve the bug issue. Any advice??

put in the cheats...hold down CTRL, ALT, C and type in rosebud, this will give you 1.000 simoleans and let you type in the other cheats, hold down the same again and put in move_objects_on that should let you delete it when your in the mode where you're shopping and such. I know this works for the first sims but dunno about sims 2. and you must be on pc aswel.
