A pest barrier comprises a back plate having a top and bottom ends and a channel formed by front and rear walls with a bottom arcuate base therebetween. The pest barrier further includes an arcuate top cap extending between the top of the back plate and the front wall such that the rear wall of the channel is located between and spaced apart from the back plate and the front wall of the channel. The rear wall includes a free distal end spaced apart from the arcuate top cap back plate to provide a gap therebetween. A kit for forming a pest barrier comprises at least two pest barrier members and a connector for securing the at least two pest barrier members to each other.
