I decided a nuc because it's very high off the ground and I didn't want to deal with weight and bulk of the separate pieces of a deep set up. Plus it is early in season. If the nuc fills up quick, i"ll stick another one up there and another frames of eggs.
As far as why waiting for the eggs. This is my first trap out and G3 suggested it above

. I do have 3 drawn frames of brood comb and lemongrass oil in the small box. I am not going to put funnel on until it warms up. I don't want bees or eggs/brood to get chilled.
I have watched both you and G3's videos on trap outs.
So, you suggest the eggs the same day I put the funnel on?
