These beetles appear in our food cupboard periodically. I assume they are larder beetles, but I don't know how to get rid of them succesfully.
I saw a mention of residual pesticides, but I'm not sure an example is and whether using it in a food cupboard would be safe.
Thanks for your help
I think this is a Scolytid beetle - one of the 'bark beetles' so-called because their larvae burrow under the bark of trees, generally causing injury or death. The adults can be found indoors sometimes after they emerge from the tree. Do you live near a wooded area? It doesn't look like one of the Dermestidae, which are the beetles which infest stored food in the kitchen.
There are beech lime and oak trees about 20 metres away. They seem to be around in the summer rather than the winter. They go for sugary things, eg honey, where you get an infestation of 20-50, though often they are around in 2-3 appearing without finding any nest. There isn't any damage to the chipboard cupboard frames as far as I can tell. No sign of wood dust.
Your various images of Dermestidae seem to show white and dark bands, whilst these seem to be dark brown all over. Size is 2-3 mm: I haven't seen any bigger ones.
Any thoughts on pesticides or how to eradicate them once we've cleared any infestations? Borax gel traps?
I forgot to mention my location in case it matters which is St Albans.
I have 'perked' the image up a little and inserted below. It's looking like The Bread beetle, Stegobium paniceum, which would indicate that you have an infested product in your food cupboards. They feed on a great variety of stored products including herbs and spices and are usually introduced to your home through purchase of an infested product. Find the source, throw it out and check that other foodstuffs are not affected and all be well in the kitchen cupboard again.
Excellent! We shall have a clear out and find where these bread beetles are lurking. My wife suspected they started when she got some dried petfood, but that is a while ago.
Out of interest, I found this link which describes where to find them and how to deal with them.
Wow, what a website! So very helpful. Thank you very much indeed.
