Just to let people know that the pantry moth infestation has now been eradicated. For those who have this problem this is what I did to get rid of it.
1. Throw away all grains whether infected or not. Check under the lids of any jars of herbs, vinegar etc as I found grubs here.
2. Clean the cupboard out with bleach and I also used Cif Power Cream. If possible remove the shelves as I found grubs on the side of the shelves.
3. Wash out every container and examine every bit of the container as I found grubs in holes in the handles of some containers. Remove these with a cocktail stick as washing does not get rid of them.
4. Put everything in a plastic container unless a tin or a jar.
5. After filling new containers with rice, flour etc put in the freezer for a couple of days to kill anything which may be lurking there.
6. I now wipe everything before putting in the cupboard ie tins and jars. I also wipe packets of biscuits and examine the packets for grubs before putting in the container.
