A portable, battery powered elongate strip is provided for deployment at the boundary of an area to be protected from crawling slugs and pests. The strip is formed by an elongate base of dielectric insulating material for placement on the ground or other boundary surface. Electrical conductors are mounted in parallel spaced apart relationship on the base in the elongate direction. The upper surfaces of the conductors are exposed for contacting a crawling slug or pest passing over the strip. Odd number conductors are electrically connected together through a first coupling and even number conductors are electrically connected together through a second coupling to provide parallel open circuits which are closed by crawling slugs or pests passing over the strip. The end of the strip is secured to a reel hub which rotates within a portable reel and reel housing for storage of the strip in rolled up position in multiple turns around the reel hub inside the reel housing. The strip is deployed by pulling and unrolling the elongate strip from the reel housing and hub. A battery is mounted on the reel hub coupled to the conductors of the strip through the electrical couplings so that all elements of the open circuits move together.
