If you have confirmed weasel or snake pressure, prefer 1\/4-inch on vulnerable openings.<\/p>\n<h3 id=\"faq-chicken-wire-under\">Can I use chicken wire under hardware cloth?<\/h3>\n<p>You can, but it is usually wasted effort. Hardware cloth alone, properly fastened, is the barrier. Chicken wire alone is not enough for exterior openings.<\/p>\n<h3 id=\"faq-apron-distance\">How far should a dig apron extend?<\/h3>\n<p>Many backyard setups use about <strong>12-24 inches<\/strong> outward. High-pressure sites may need more. Continuity at corners matters as much as width.<\/p>\n<h3 id=\"faq-inside-outside\">Should hardware cloth go on the inside or outside of the frame?<\/h3>\n<p>Outside is usually better so predators cannot pry mesh away from the frame as easily. Some builders sandwich mesh between layers. Either way, edges must land on solid wood and be washer-fastened.<\/p>\n<h3 id=\"faq-ventilation\">Will hardware cloth block ventilation?<\/h3>\n<p>It reduces free area slightly but should not replace your vent plan.
