I have a spider's web on the balcony that I feed with flies or mosquitoes, inserted with tweezers, I rely on the geckos to keep the population of them down to a manageable level, but I still get bitten regularly by mosquitoes, and the flies are a pain when eating outside. The moths here get into everything, including porridge oats, so they aren't encouraged either, but I do try not to kill anything, even the ants, which I strongly believe will eventually take over the world.
