Bird Repellent

posted this on Aug 4, 2016

4 THE BIRDS® is a transparent compound which is applied to places where pigeons and starlings rest, roost or nest.

4 THE BIRDS® contains polybutene which is used in chewing gum, surgical bandages and lipstick and will not kill birds when used according to package directions. Also, because of its unique chemical formulation, 4 THE BIRDS® will retain its effectiveness for up to one year (under most weather conditions). Therefore, birds learn to avoid areas treated with 4 THE BIRDS® and seek new locations for roosting.

Many pest control experts recommend 4 THE BIRDS® as the best way to solve pest bird problems.


4 THE BIRDS® gel bird repellent is applied with a standard caulking gun. Before inserting a cartridge of 4 THE BIRDS® into the caulking gun carriageway, simply trim the end of the plastic spout to a taper. Leave the lip on the spout for replacing the cap on partially filled cartridges, and puncture the seal. Always remember to replace the cap on the tip of any partially filled caulk tube.


To apply 4 THE BIRDS®, keep the tapered, flat section of the cartridge spout upper-most, but resting lightly on the surface to be treated. Then, draw the caulking gun slowly towards you while applying steady pressure on the trigger during the full distance of travel.

This technique provides a solid bead (strip) of 4 THE BIRDS® repellent approximately 1/2" wide and ensures satisfactory results.

Don't waste 4 THE BIRDS® with haphazard applications. Instead, be systematic:

• Clean surfaces before application; remove dead birds, nests, etc., then wire brush or scrape the surface to remove dust, dirt, loose paint, droppings, etc. Wearing rubber or other nonporous gloves and the use of a respirator is recommended. On porous surfaces, such as stone or unpainted wood, the surface should be sealed prior to 4 THE BIRDS® application; brush or spray on a coat of shellac or a 50% solution of white glue, then allow to dry. The use of drop cloths to protect areas below applications is highly recommended.

Treat all the landing places on the entire building for best results.

such as rain gutters, roof peaks, ornamental trim, rose windows, portholes or column caps, generally one 1/2"bead (strip) is enough;

such as eaves, chimneys, downspouts, dormers, bell towers, fire walls (parapets), electrical signs and related structures, I-beams and braces, air conditioner and heating ducts, additional beads may be needed. Furthermore, some birds tend to overshoot their intended landing spots requiring additional strips of repellent. To be effective in these situations, apply 4 THE BIRDS® as follows:

a. Surfaces four inches wide or less, apply a 1/2 " inch diameter bead approximately 1" in from the outside edge.

b. Surfaces four to eight inches wide, apply two beads about 2" apart, with the first bead 1" in from the edge and the second bead located about 2" in from the first, (3" in from the outside edge).

cWider surfaces, apply three beads, with the third bead located about 2" in from the second (5" in from the outside edge).

- Where the tops of railings require bird-proofing, first protect the railing by covering with cloth tape; then apply 4 THE BIRDS®over the tape. Also treat floors of balconies beneath railings 1" in from the outside edge. Be sure to caution residents to stay clear of treated areas. Remove the tape from the railing after the birds no longer return to the area and remove any adhesive residue left by tape.

- Apply where birds have been roosting or are likely to roost.

- Apply 4 THE BIRDS® along the outside edge of the chimney cap and along the flashing where the chimney joins the roof, a place where birds nest and seek warmth and shade. On the chimney cap, apply a single bead 1" in from the outside edge.

- When birds nest in these areas, they clog the natural flow of water. This often results in expensive roof and interior water damage.

Treat the outermost tip of gutters, laying a continuous 1/2" bead the full length of the gutter. There should be breaks in the bead to allow water to flow into the gutters. Downspout curves under roof overhangs are occasionally the sites of nests and concentrated droppings. In order to treat the area properly, it is important to remove all nests and clean the surface before making application of 4 THE BIRDS®. After this has been done, apply two beads, beginning 1" in from each outside edge.

­In the cases of pitched roofs, treat the entire length of the roof ridges (including eaves and dormers) with at least one continuous bead of 4 THE BIRDS®. Don't forget to treat the flashing where eaves and dormers join the roof. Lay a series of broken beads 2" to 3" apart. Protrusions, if any, under the eaves of a dormer require treatment because birds build nests in these sheltered areas.


Although they vary in shape and size, these areas are treated like any other pitched areas of buildings. Steeplejacks can be hired on an hourly basis to work on ridges and other normally inaccessible areas where rigging and ladders cannot be used.

If gutters surround the tower, remove nests and debris and treat the gutters and tops of downspouts.

Screening in front of bell tower openings may be required after 4 THE BIRDS® application, since birds will not alight on treated areas, but instead may seek shelter inside the bell tower itself.


Usually capped with stone, tile, asphalt, shingles, wood, tar, metal, etc., a parapet is the extension of a wall above the roof line of a structure. On parapets four inches wide or less, apply one 1/2" bead of 4 THE BIRDS® approximately 1" in from the outside edge; on parapets four to eight inches wide, apply 4 THE BIRDS® in two parallel beads 2" apart, beginning approximately 1" in from the outside edge; on wider parapets, apply three beads 2" apart, beginning 1" in from the outside edge.

(i.e. "ginger-bread") -

Be sure to clean all droppings from the ornamental trim before applying "4 THE BIRDS"® to all landing and nesting areas. Remember also that in order to retain the beauty of ornamental trim, it is imperative to be as neat as possible. Since ornamental trim is usually narrow, simply apply one 1/2" bead of 4 THE BIRDS® to surfaces.where birds land.


Since birds do not roost on vertical surfaces, it is only necessary to treat the horizontal roosting areas of rose windows with 4 THE BIRDS®.Generally, one 1/2" bead along the edges is enough. Wider ledges may require two or more beads. Treat portholes in the same manner as rose windows. If there is a cornice wide enough to serve as a landing site for birds, it should also be treated.

HINT: Pay extra careful attention to church rose windows when applying 4 THE BIRDS®. These windows are extremely expensive to replace and are considered works of art.

- Birds are likely to roost and build nests in these areas, found on the fronts and sides of buildings where letters have been mounted to spell out the company's name. Bird droppings make the signs and areas around them unsightly.

To calculate the amount of 4 THE BIRDS® required to treat a sign, measure the lineal footage from one end of the sign to the other, and multiply by three for estimating purposes.

Don't forget to
 add rods, pins, or structural steel frameworks that support the letters for applying the Birds®.

LETTERS - Be sure all electrical current is turned off before attempting to apply 4 THE BIRDS®to lighted signs. Tar flashing, as well as the rest of the deck, may have to be cleaned thoroughly prior to application (this should be considered a billable expense). Apply 4 THE BIRDS® to all supporting beams and braces above and below the sign or marquee; the number of beads (strips) will depend on both the severity of the bird problem and the width of the surfaces.

It may be helpful to have representatives from the sign service company present during application to ensure that 4 THE BIRDS® is not applied where personnel will be walking.

Apply 4 THE BIRDS® in 1/2" beads approximately 1" in from the outside edge of the cap and all areas adjacent to it, wherever evidence of birds is found. Remember, besides being functional, columns and caps are often designed to be attractive; therefore, neatness and attention to detail are both important considerations!
