Defender® Bird Post and Wire Packs

The Defender® Bird Post and Wire Holder system keeps birds off ledges, sills, and flat roofing. It is a low visibility product that requires no measuring and no power tools, making it much quicker to install than other available bird wire systems. Our bird post and wire deterrent is favoured by architects as the base requires no drilling into the ledge. This system protects listed buildings from the damage that can be caused by drilling, which in turn can lead to water ingress and stress fractures.

Easy Install

Each 33 cm moulded strip can hold up to 11 posts. This system means the first post is taken right up to the very front of the leading edge to be protected, even if the ledge is rounded or part-missing. Any small sections that are uneven or damaged are simply bypassed and supported by the rest of the base.

Silicone Fixing Holes

There are 43 holes along its base through which the fixing silicone oozes when the base is pressed in place. This creates a lock to give a strong, permanent hold.

Snappable Sections

There are 11 breakable sections along the base of the Defender® Bird Post and Wire system that can simply be snapped apart with your fingers to shorten the strip if required. The bird wire strip is then just glued into position.

Anti-Topple Stabilisers

The patented base has anti-topple stabilisers to prevent the posts from inward collapse. If a large bird attempts to land on the wires, the force of the bird is shared down the length of the strip and the anti-topple stabilisers, making it impossible for the Defender® Bird Post and Wire system to collapse in on itself.

    Defender® Bird Post and Wire Pack - Key Info

    Which birds do Post and Wire work for?

    • Pigeons
    • Seagulls

    Previous bird wire systems were notoriously difficult and complicated to install and required professional bird control technicians to put them into position. These systems required precise measuring, drilling, and specialist tools. The Defender® Bird Post and Wire Holder has been designed to simplify installation and make it accessible for all property owners.

    Why should I use a post and wire system?

    Post and Wire bird control systems are often preferred by customers who require a low visibility system to deter birds. Often post and wire is the go-to solution for listed buildings and can be specified by architects and project managers. It is also a good option when there is a large flat area such as a roof, that needs protecting from pigeons or seagulls.

    Why is the Defender® Bird Post and Wire Holder System innovative?

    The Defender® Bird Post and Wire Holder system comes in pre-formed 33 cm strips complete with 11 posts. Using a full strip means the first post can be positioned on the front of the leading edge, and the posts behind it will be perfectly spaced so no measurements are needed. The strip itself adds stability to the posts and also bypasses any sections of the ledge that might be uneven or damaged. It is fixed onto a ledge using silicone, ensuring there is no damage to the stonework. Traditional install methods would drill into the ledge, which can cause water ingress and splitting.

    How can post and wire systems protect large flat roofs?

    Flat roofs can be quite tricky to proof against pigeons and seagulls. Using Defender® Bird Post and Wire Holder systems, large areas can be proofed quickly and easily. The wires that connect the strips can be tied off every 2 metres and for a longer stretch, the wire is simply attached to the other side of the strip and carried on to the next post strip.

    Convenient Pack Sizes

    Defender® Post and Wire System can be purchased in 3 convenient pack sizes containing everything you need to carry out a successful install. All packs include all the tools needed to install the post and wire. Pack sizes come in a 2 m² pack (containing 75 metres of wire), 6 m² pack (containing 200 metres of wire), and 12 m² pack (containing 400 metres of wire).

    How to install Defender® Post and Wire

    Defender® Bird Post and Wire Holders - Photographic Installation Guide


    Defender® Post and Wire Strips are the favourite bird-proofing system recommended by architects, especially on listed and historic buildings. The reason for this is due to the low visibility of the wire from the ground. Traditionally, Post and Wire was a complicated system that required drilling and specialist tools. However, Defender® Post and Wire negates the need for all specialist knowledge and equipment.

    Step 1 - Clean the Area: Before you begin, the area needs to be properly cleaned to ensure the Defender® Post and Wire strips can be siliconed securely to the surface and not stick to any loose debris. Scrape and brush any loose dirt off the ledges. We recommend using warm soapy water and a disinfectant spray like Germ Clear™ Bird Droppings Disinfectant Spray especially if the ledges have pigeon or seagull droppings on them. Leave the area for 24 hours to fully dry.

    Step 2 – Spacing: Work out where you are going to place the strips - 2 rows of strips is ample to use for a ledge up to 2 metres long. The strips are placed with the double-headed post as close to the leading edge as possible with the anti-topple feet pointing towards each other to aid stability. If the width is smaller or wider than a strip, it can simply be broken into smaller pieces or additional pieces added to the row.

    Step 3 - Silicone: Use Defender® Fixing Silicone Adhesive to glue the Defender® Post and Wire Strips into position. It is important to check the suitability of surfaces for use with Defender® Silicone. Always do a tester of one strip if you are unsure. For more information, please visit the product page Defender® Pigeon Spike Fixing Silicone. Press the strips into position allowing for the silicone to ooze through the silicone locking holes, creating a strong bond and lock. Continue to silicone into position all the strips along the ledge or surface that is being proofed. Leave for 24 hours to cure before starting the wire install.

    Step 4 – Attaching Wires: Working towards yourself, wire up every post including the double-headed posts on the leading edge. Unravel enough wire to cover the length between the posts allowing for a little extra for attaching and crimping. Thread a single crimp onto one end of the wire, then through the closed loop on a spring. The wire is then threaded back through the crimp. Push the crimp closer to the spring and using the crimping tool, squeeze the crimp shut, creating a secure tight fix, and locking the wire into position. Attach the spring to the eye in the post using the open loop on the spring.

    At the other end of the wire, thread on another crimp and then through the opposite post's eye. The wire is then pulled through the eye in the post and pulled taut, but not so taut that it causes the post to lean inwards. The wires have a little bounce in the perfect install. Push the end back through the other crimp and push the crimp closer to the post, then secure using the crimping tool. The ends of the wires can be trimmed leaving 2.5 – 5 cm spare. Add a wire to every post along the strip and alternate the side the spring is attached.

    Step 5 – Lengths longer than 2 metres: Two metres is the maximum length the wire can be run between 2 rows of Defender® Post and Wire. For longer lengths more rows can be added, each up to 2 metres distant. Wire up the first two rows as described above. You do not need to add an additional strip to the centre if you need 3 rows. The eyes in the centre row can be used again and are double-stringed. Again, alternate the spring. If one side already has a spring attached, start with just the wire and vice versa. The third row should be installed with the anti-topple pins facing the other rows.

    How to Calculate Which Pack Size to Buy

    Simply measure the length of the ledge or area to be proofed in metres and multiply it by the width.

    Example 1
    A flat roof is 8 metres by 0.74 metres so 8 X 0.74 = 5.92 m²
    Therefore a 6 m² pack is required.

    Example 2
    A wall top is 5 metres long by 0.25 metres wide so 5 X 0.25 = 1.25 m²
    Therefore a 2 m² pack is required.

    Remember the bases can be easily made smaller by snapping between your fingers so every size length ledge or space can be fully protected.
