Inspector Jason Booth, of the Sheffield South East Local Policing Team, said: "I know the weather is good but remember to close windows when you go out and keep doors locked if you are down the garden."
A spokesperson for the Sheffield South West Local Policing Team, added: "You will have noticed from recent updates that a number of burglaries we've listed have happened at properties left insecure.
"Please remember to lock all doors even if you are in the house and close or lock windows when leaving rooms unoccupied. Whilst we're all making the most of the recent weather it seems unfortunately so are our burglars.
"A number of valuable items have also been taken recently from vehicles. Again, please ensure that items are not left in vehicles wherever possible especially on show. If you have a vehicle alarm make sure it is working and set as this does deter thieves.
"Lets not make life easy for them."
