It’s troublesome to find birds using your window air conditioner as their stomping grounds or building a nest in your air conditioning unit. Bird droppings are unsightly, carry disease and could even keep your unit from functioning properly. The constant noise that the birds make may disturb your sleep. No one wants to be responsible for the death of any birds, especially baby birds, so the best solution is to keep the unit sealed up and unattractive so that birds are not tempted to come near it and not able to roost on top.
- Remove any bird feeders or bird baths near your air conditioning unit that attract birds to the site. Take away any leftover nesting materials that the birds may want to reuse.
- Look for holes on the sides of the unit to see if there are areas where the birds can actually go inside. Remove any leftover nesting material and cover the holes with pieces of plywood or fine mesh.
- Fasten a board or piece of cardboard on top of your unit at a 45-degree angle so the birds can’t land on top of it. When they land on the angled side, they will slide off.
- Spread bird netting across the window ledge where the air conditioner sits. This will prevent the birds from landing. A child’s metal spiral toy works in the same way. Nail it to the ledge with the spirals two-fingers’ width apart. The spirals don’t provide a sturdy enough landing place for the birds.
- Stretch bird netting 1 inch higher than the entire air conditioner if it doesn’t interfere with the functionality of the unit. Since the netting is flimsy, the birds won’t be able to grasp it and stay upright.
- Look into distracting mechanisms. Hang some CDs from thin wire. The sun’s reflection off the silver scares birds away. Place some fake owls nearby. Look at other bird deterrents such as silver tape, bird spikes or bird gel.
- Remember that the birds’ development period in the nest is short — only three weeks at the most. If you find a nest in your unit, be patient until they are through with the hatching process. Eliminate any pieces of the nest after the young birds take flight and take immediate measures in preparation for spring of next year.
