This year again my first ripe strawberries in the polytunnel are being eaten by little black beetles, which I think must be sap beetles. Is there a biological control, like nematodes, I could use to kill them off, and if so, how long would that take ? Can I spray them with anything, eg soapy water, garlic (don't think I fancy the combination of tastes !) or anything ? The plants are loaded with small unripe fruits at the moment.
