Summer students disrespectful of my home.

Whilst not religious myself, this seems quite apt.

Luke23:34
Father, forgive them, for they know not what they do.”

Poor kids, they must be counting the days until they go home, what a pleasant host you sound 😂

Stop moaning about the kind of food they eat, but do tell them to bin the leftovers and not leave it to rot in their bedroom.

I can't believe you are offended by "stranger's food" in your house, do you realise how ridiculous that sounds?

This. I mean they can have a huge dinner and then be starving half an hour later. It’s bizarre but normal.

I still want to know what food you cook, I need some inspiration!

This.

I've worked with international students for many years in this age group. This isn't worth a fuss and agree with previous posters as to how to deal with it. It is simple teenage thoughtlessness and a breezy reminder to use the bin will suffice.

Alternatively, ask the organiser of the summer school who is dealing with pastoral care / accommodation to have a word. They will have seen it all before. Trust me, there are a lot worse things you could be dealing with as a host mother!

My grandmother hosted foreign language students for years.

She had very strict rules, similar to when she had her own kids living with her.

Rooms had to be kept clean and tidy at all times. Beds had to be made every morning and bins emptied. She would check their rooms every morning when they left and pick them up on it as soon as they returned if they hadn’t done something. Food had to be eaten in the kitchen and nowhere else. Laundry had to be brought downstairs and separated on set days. They had a strict evening curfew.

She was also very kind, generous and warm towards them and most returned year after year.

She said it was important to have clearly laid out rules and expectations and not to waiver from them. Especially as there was often a language barrier and cultural differences.

They may have enjoyed and appreciated your food, still been hungry and gone to the supermarket. Teens can have big appetites.

Did you not set some house rules when they got there. Ask them not to take food upstairs. Empty any rubbish out of their bag before taking it upstairs. I don't allow food in bedrooms it's. A brew maybe but never food.🤢🤮

Tell them to put the food in the bin & remind them throughout the week.

Teenagers are well known for not keeping their rooms tidy. I wouldn’t entertain the idea of hosting students of this age again as it sounds like it’s causing you stress.

irritated about rotting food I can understand.

You however have ZERO right to restrict their diet or get mad about where they get food from or what they eat... are you always that controlling?

You’re massively over reacting. Do you have children?

At least you only have one more week, nothing too horrendous will happen in that time.
If you are meant to be in their room, then just mention that food needs to go in the bin or you’ll get mice/bugs.

If you aren’t meant to be in their room then I’m not sure how you bring it up. Tell them you’ll be hoovering the next day and hope they have a minor clean up?

This. Cut them some slack. They don't like your food, they're a bit bad with rubbish but they're only 15 and away from home.
They're not 25 year old lodgers.

Mature ... :D

I usually am the one to say the MN bunch is sometimes ott but in this instance you sound like a 15 yo yourself. :D

Sorry don't get the fuss. Show them the bin, ask them to throw away left over food and done. They have a week left and will be out of your hair in no time.

I worked for a language school for a long time and these kinds of gripes were fairly common. You could maybe just have a polite chat with them about the mess, or you could contact the Accommodation Manager in the school, who might be able to advise you or chat to their group leader (if they have one).

You posted a vile post on someone else's thread and have the audacity to say people are being horrible to you when you posted a thread saying/complaining about one thing - including calling them disrespectful in your title - made a shit joke that no one got because it sounded exactly in line with what you'd posted in seriousness and are now backtracking. Sounds like instant karma ironically

NRTFT SO I suppose someone has already suggested this, but in case no one has…

Explain to them that this is unacceptable. If they are “Homestay” students and the issue continues despite the initial warning, call their Homestay Coordinator at their course provider and ask for them to address the issue with the students directly, if the issues continue ask for the students to be removed. Most of the times the threat to be moved to an emergency short term host or to a host far from the school/friends is more than enough to bring them in line.

OP, I would just ask the kindly NOT to leave food to rot in their room.
THEN ask them are there any other items you can get for them to eat for lunches etc.

Rotting food is not on in rooms.
Just ask them not to do it.

You also said I'm so annoyed I'm afraid I will overact with them. You would be VERY wrong to do this. They are very young. Stop and think.

I think it is fairly common, don't take it personally, I have had students often blatantly ignoring the no-food-in-bedroom rule I implemented after we had the first lot, who left rubbish including food in the drawers (I never cleared drawers for any more students after that but let them live out of the suitcases). Have a calm word with them and also let the family person from the language school know. Also ask them what they like to eat and get them to make their own sandwiches them food shopping with you if you are happy for them to choose stuff. Be patient. Good luck!

Just tell them not to keep food in their rooms and they need to make sure lunch boxes etc. are emptied in the kitchen bin, but don't make a big deal of it.

I had a teen relative stay and after she left I discovered multiple empty biscuit and chocolate wrappers in her room and crumbs everywhere. I felt quite bad that either she had an eating disorder or didn't like what we were feeding her ( she was a very polite vegetarian who didn't like vegetables so it was tricky).

You are presumably getting paid money to host these girls, so don't take it personally.

Just cheerfully say to them, "hey you guys, Let's make sure we throw out any food we have left over so we don't get bugs. Cool? Great! Good job!"

Although the general sentiment is good, this may confuse them and they’ll think they’ve landed up in the USA by mistake!

Well that's definitely not how your original post reads to other people !!!!!! You were very annoyed they ate other food

OP, I got it, tongue-in-cheek, check!

You've posted on AIBU. That makes you guilty of something no matter what you say... not many here do nuance or even basic comprehension.
