1. Pull everything out of your cupboards and throw away anything that is out of date or that you know you will never use again. Have a good nose through packets you haven't used for a while.

2. If you see insect webbing, it's a sure sign of flour moths. They will have got into everything stored in packets and boxes so you'll have to throw them away. Wash and dry the cupboard well (paying extra attention to corners, where eggs are laid) before putting stuff back. Any open packs of flour, sugar, matzo meal etc should be stored in plastic containers – less likely for beasties to invade.

3. Buy dry ingredients such as flour in small quantities (see above!)

4. Don't store nuts in the cupboard – they keep longer in the freezer. Use straight from frozen
