Fire sounds like an awesome step, but I am a bit worried. In part because my wooden deck is RIGHT near the hole they are flying into, I don't want any thing to set fire and spread to the house, you know? I should probably take a couple courses on fire safety before trying any thing like that. Plus, theres a chance the fire wouldn't even reach far enough into the hole to hit whatever nest they're sitting on. Ugh, they ARE terrifying! I've been observing them fearfully and increasingly insanely through the window.
