Bird B Gone MMSWALLOW Swallow Shield, Clear | Transparent 3"x11" Adhesive Strips, Physical Nesting Prevention, Virtually Invisible Protective Barrier for Eaves & Overhangs

Amazingly difficult to see even although just above my front door, so pleased with that. Swallows don't like it and have disappeared 🙂

These don't work its just piece of plastic and fishing line the house Martins just fly through it and build there nest in it they definitely don't work I bought 3 of them and took them down there no use at all.

Works very well and is invisible so does not interfere with the look of your home. Easy to install with the sticky pads and feels secure.

The fast delivery is all I can give this item. Swallows are still building nests within the area, it doesn't seem to be stopping them at all.

Sadly this product didn’t work. The swallows built a nest behind it !! Persistent little chaps !!

This product is almost invisible when installed. It completely deterred cliff swallow from nesting under our roof peaks. Yes the swallows are lovely but they make huge mud nests and are very dirty. Best they nest in actual cliffs. This product worked perfectly.

Repeat customer here. A couple years ago I solved a recurring problem with phoebes building their nasty nest in the corners of my front porch. Nothing had worked until I installed these simple filaments. Two years later the filaments are still in place but no more phoebes. I just bought some more to deter them from a new location: above an exterior light. The perfect product: it's cheap, it's simple, and it works! I cannot speak to its use with swallows or bats.

The bat crawled right up through the stuff and is happy with it there. does not work with bats!

We have barn swallows that like to build nests under our eaves and around our porch support posts. For the most part we enjoy having them there to help keep down the insect population. They are aerial insectivores, catching their prey while flying. This includes a variety of insects such as flies, beetles, wasps, wild bees, winged ants. They also consume moths, damselflies, grasshoppers, and other insects, as well as some spiders and snails.However, they also like to attempt to expand their neighborhood every spring by adding new nests. And that is where we draw the line. We have found that these strips of plastic with clear monofilament line and an adhesive surface to attach them have proven to be very effective at limiting their expansion to unwanted areas of our porch.They effectively prevent them from landing on the parts of the porch we want to keep clear by confusing them when their wings hit the clear lines hanging down about 10 inches from the surface. In order to build their mud and grass nests, they need to be able to land to build the nest.I can highly recommend them as a natural, non-harmful, effective way to control access to areas you want to protect from them building upon. The strips are very durable and the stickiness of the adhesive they use is very good, having survived the heat and cold of central Texas for over 3 years since we started using them. This makes them a very good value for the money in my opinion.

Update, the swallows knocked down this junk and built their nest where it used to be. I reiterate, this is junk! So we installed these just outside our front door where the barn swallows nest each year. About an hour after the installation, I see a barn swallow sitting on the start of a brand new nest, directly behind the little strings, (which is just fishing line by the way) and I swear that flipping bird smiled at me. Well year after year I have to wait until the little birds hatch and defecate all over the brick and the porch and then I get to power wash the leftovers and bathe in their filth. This product deterred nothing! I knocked a full blown nest down today and the birds are constantly flying in and out (no eggs, don’t panic). What a total waste. The product stayed in place but the birds used it as a curtain so they could make more birds behind it. My suggestion is get your own fishing line and hang a few for less than a buck.
