In areas which are covered like under the sofa, I keep finding small white soft things which look and are the size of grains of white rice. I kept hoovering them up but then decided to collect some and put them in a jar to see if they were larvae which would transform into some sort of bug. I could see that there were tiny caterpillar-like creatures in the white 'cocoon' but then they stopped wriggling and eventually died after a few days. The caterpillers had black heads. Have googled 'carpet bugs' and images do not match up to anything I have seen. Any ideas?
I agree, moths. Found them under a wicker basket in DD's room, 3 weeks after we laid the carpet. I did get rid of them though by steaming the carpet every day for a week and then every week for a couple of months. They have not returned and I am super vigilant. The carpet was left with horrid patches but luckily only under the basket, which I disposed of pretty quick!
