Termites finally arrive

Well the termites finally found where I live and invaded with enthusiasm. They politely come in through the front door, under it actually, go the length of the lounge, and into the kitchen, a distance of 40 ft. They are into everything, especially ginger biscuits and the bin bag, they are tiny but hunt in such large numbers it’s quite impressive. I haven’t tried to kill them off, just thrown out the food they got into and check everything regularly.
