{"title":"Woodworm \u0026 longhorn beetle","description":"\u003cp\u003eRound holes in a beam and a small pile of fine dust beneath: that is the classic sign of woodworm larvae living in the wood. In this category you will find products to treat affected wood in sheds, stables, lofts and outbuildings: the Edialux woodworm treatments Perfacs and Perwood, Resoluut Houtworm Concentraat and Wolsit KD 10. They differ mainly in pack size and in whether you buy them ready to use or as a concentrate.\u003c\/p\u003e\n\u003ch3\u003eWoodworm or longhorn beetle?\u003c\/h3\u003e\n\u003cp\u003eWhat you see determines how big the problem is.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eCommon furniture beetle (woodworm)\u003c\/strong\u003e leaves small, round exit holes of about 1 to 2 millimetres, often in furniture, floorboards and older structural timber.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHouse longhorn beetle\u003c\/strong\u003e makes oval holes of about 6 to 9 millimetres and mainly attacks softwood in roof structures and joists.

A whole roof structure or many square metres calls instead for a concentrate such as Resoluut Houtworm Concentraat, or for Perwood in a larger pack. Calculate consumption using the dosage on the label and the area you are treating. Some large packs and concentrates are aimed at professional users; check on the label who may use the product.\u003c\/p\u003e\n\u003ch3\u003eHow to tackle it\u003c\/h3\u003e\n\u003cp\u003eThe product must be able to soak into the wood. So first remove paint, varnish or wax and vacuum away bore dust and dirt. Then apply the product with a brush or sprayer, and in badly affected spots also into the exit holes. A suitable pressure or knapsack sprayer is in \u003ca href=\"\/collections\/pressure-sprayers-and-dusters\"\u003espraying equipment\u003c\/a\u003e.
