I found lots of info from spraying with soapy water to the good old vacuums but they hide under my siding where I can't get to them. I tap on it and when they scramble out I get them with my Dyson! But it's just the tip of the iceberg! Is there a spray, natural or chemical that I can use on my siding for a residual affect? Thanks!
