edge-to-edge

Edge-to-edge feature of Spider-Trap-4 from Traps Direct has the sticky glue of the trap field all the way to the leading edge of the trap. Also referred to as Zero-Margin or an Ambush Edge, the design prevents ‘early warning escapes’ observed when insects detect a change in the surface they are traveling.
Most insect monitors and spider traps have a glueless entry margin that reduces trap effectiveness by alerting a crawling insect that something is different ahead of them.
Most studies point to a 50% improvement in catch rates through use of edge-to-edge traps.
