Rodents in cavity walls of terrace ‘blay’ house.

[joannerooks]

Good morning,
We have been struggling to rid our property of rodents who have managed to get into the cavity walls. We finally got rid of the decking and hoped that would solve it but they are still entering. We now are considering the possibility they are entering through an air brick under the floor. We have a 1930s terrace ‘Blay’ house in sw London which has a 3 m single storey extension. We have wondered if there is a broken air brick under the floor connecting to the property next door (entry seems to be on one side) Any advice would be very helpful.

- Massive job but is it possible to lay a concrete floor throughout a property (which has a floating floor) I’m concerned about damp.

- we have a drain running under extensions. Is it possible they can enter through there? Thames water did survey with camera and no damage to pipe.

Thanks for any suggestions.

Laying a concrete floor without curing the source problem means that it will be much more difficult and expensive to repair it later.

This is sometimes found when a leaking pipe or drain causes damp and has been concealed under a slab.

Rats need constant access to water so are fond of leaks.

The food source might be bins, bird table, drains or animal feed.
