Why is it a good idea to have wool in carpets?

[minkah]

Why not just have cheaper polypropylene ones?

I need to carpet my living room and am bit puzzled by choices.

It's fatiguing my brain cell.

We had moths in the wool carpet we inherited with the house.
We used this stuff: www.johnlewis.com/acana-carpet-fabrics-moth-killer-and-freshener/p231892921.

It killed them all very dead. They are the same moths as the ones that eat your clothes. We didn't know we had them until we moved a piece of furniture and there was no carpet left behind it.

This is what moths did to our carpet.

Try again.

Thanks for the tip Pipbin. A good moth is a very dead moth.

I just ordered a robot vacuum thingie to get under the sofas and no more floor clutter will be allowed.

Having carpet moths..DO NOT WANT.

Looking forward to the robot vacuum!

Not sure how to get all the wires off the floor, there are lots of extension leads lurking under the sofas..really don't know what to do about them.
The cat sometimes dumps a dead mouse under the sofa, too. Don't know what a robot vacuum would do in response to a corpse...

Oh, just saw your posts pipbin.

Well done for getting rid.

I have had cashmere jumpers eaten through... And wool ones ignored.

Moths seem to me to be very very selective about what they eat.
