XPCARE105 Feet Bird Spikes, Stainless Steel Bird Spikes Fence Spikes for Crow Robin Pigeon Squirrel Raccoon Defender Spikes (100 Packs)

Self-assemble. It's an IKEA version of bird spikes. Very time consuming to thread through all of the spikes and click to them to the base. However, once assembled, the spikes are very effective and cost effective compared to other on the market. It definitely deters the pigeons from gathering on our rain spouts.

These work great deterring birds and squirrels. (This is my second time ordering this product.) Easy to assemble. Thread the spikes through the holes and then squeeze together and pull until you hear a snap.

You will need to use pliers to snap most of the spikes into place. The spikes that run parallel to the strip are ok to push in with just your fingers, but the perpendicular holes are “off” in that you need pliers to snap the spikes into place. As you could see in the picture, the perpendicular spikes don’t push all the way in… need pliers to snap them down and in. This makes a tedious task even more difficult. If the spikes aren’t snapped into place, they move around too much. I have some of these bird spikes from another company and did not have this problem.

The holes where the spikes go in are little too small. I had to use a hammer to drive them in.

I think the item will work just fine deterring dogs from doing their business under my tree. However, my fingers got sore & dirty from putting all the spikes in. I didn't read that they needed to be put together. It was time consuming as I had to put together 20 strips & tightly fasten them, some were hard to push & make them snap. I'm just glad I didn't need to do anymore.
