Might get some peace from their squawking! The birds 'round here are mental.
Tell me about it. I live by the beach so we get a mix of all different types of birds shitting all over the place (mostly seagulls). Lots of fishermen too who leave dead fish in the sand so they fatten up then come shit on my house and leave eggs everywhere.
HOWEVER. I figured out a very effective solution to get rid of all birds within like a 300 yard radius... somewhat accidental.
Last summer, I built a very powerful 4 gallon (gas) per minute HHO steel cutting torch. It runs off water and electricity (12V, 100A), uses KOH as a catalyst which splits the water into 2 parts Hydrogen and 1 part Oxygen. The gas itself is
ridiculously powerful. It gets hot enough to cut through anything. Steel rebar, fire brick, master locks, fence posts... etc. I used it to take out a HUGE tree stump in my backyard. I had tried EVERYTHING trying to get rid of that stump. Saws, stump remover, axing at it for hours on end. Then I drilled over 100 holes in the stump, started a coal fire over it and let it burn for 2 days straight. Came back and notice it didn't do shit. It only burned through the outer 2 inches. Tried a rope and my brothers pickup truck. Nothing worked. Then months later when I made this torch, I was able to cut right through the dirt ground, cut through all the roots and the center of the stump itself in less than 30 minutes and pull out all the pieces. I was amazed.
Anyway, if you run the gas through soapy water, then light the little HHO bubbles EVERY SINGLE TIME the detonation BLOWS OUT YOUR EARDRUMS.
Here's an example:
So naturally, if you put it in a balloon, the sound is sooo fucking loud, the concussive wave so strong it tricks the birds into thinking a thunderstorm is coming and they all evacuate and seek refuge.
Here's how the pro's do it: (FF to 29:50):
