Signal word
4 The Birds Bird Repellent: Warning[1]

Keeping small birds out of the gel

Don't apply it anywhere desirable bird species might get stuck. Oversized beads raise the risk, so the label repeats that beads must never be wider or deeper than half an inch.[1]

Where it is used

Clean first. Wipe or scrape off dust, dirt and droppings so the gel sticks, and seal porous surfaces with one coat of shellac or a 50% white-glue solution before applying.[1]

On ledges and sills, run beads no closer than 2 inches apart, starting 1 inch in from the outer edge. On roofs, peaks and cornices, one bead along the highest point is enough.[1]

Heavy bird traffic can flatten the beads, and a second treatment may be needed. Recap a partly used tube on its tip.[1]

Use mineral spirits to remove the gel from treated surfaces, tools or anything else it gets on.[1]

Safety and environmental hazards

People

Signal word WARNING: causes substantial but temporary eye injury and is harmful if absorbed through skin. Wear goggles or a face shield, avoid skin contact, and wash up before eating, drinking or using tobacco.[1]

Pets

Store it in the original container where children and pets can't reach it. The label's skin and eye warnings apply to people and domestic animals.[1]

Bees and pollinators

The label carries no bee statement; it is a sticky gel laid on building surfaces, not a spray on plants.[1]

Fish and water

Its key environmental hazard is to birds: small birds can become fatally trapped in the tacky gel. Following the directions helps protect species covered by the Migratory Bird Treaty Act.[1]

One 10-ounce tube treats about 10 linear feet with half-inch beads.[1]
How do I get polybutene gel off a ledge?
