One man who is opening his home to Ukrainians says Irish people were once homeless and hungry.
James Murray from Co Mayo says his three grown up children have all left home in the last six to eight months.
He told The Pat Kenny Show he felt he had to do something.
"We have a four bedroom house - one bedroom is full of rubbish from the other two rooms.
"So we've cleared two rooms and got them ready for a family that hopefully will be with us in the next couple of days
"It is of course a big thing to do... we will have language barriers and we'll have different things to cope with.
"But which of us would swap our life here for their life there?
"I have to compliment Poland in what they've done, it's absolutely brilliant and they're really shining a light for us.
"And so whatever we can do here, why wouldn't we?
"Our nation and our history left us homeless at one stage, and hungry, and we really should do what we can if we can".
'We all wanted to do something'
James says he has also being donating whatever he could.
"When the war kicked off originally, I think we all wanted to do something - whatever we could do.
"Initially our very first thought was to donate whatever we could.
"We have an ambulance company ourselves, so we boxed up as much ambulance equipment and bandages and whatever to donate to Ukraine."
James says he came in contact with the Castlebar-based charity Candle Of Grace, which has helped children from the Chernobyl area.
"On speaking with Lily, the organiser there, she was inundated with donations at the time.
"She also said it will be very apparent, very quickly that refugee families needed somewhere to stay.
"And at that stage, around this day last week, there really wasn't any firm direction coming from Government."
People are being asked to provide accommodation for Ukrainian refugees for up to one year.
The Irish Red Cross is encouraging people to pledge offers as Ireland is expected to take in around 100,000 refugees.
The charity says support will be provided to those who open their homes to a Ukrainian refugee.
The UN High Commissioner for Refugees says the flow of people who have left Ukraine has reached two million.
Poland's Prime Minister Mateusz Morawiecki says 1.2 million people have arrived at its border since Russia's invasion began.
His department says border guards processed over 140,000 new entrants on Monday alone.
