I am looking for organic / plant solutions (no DEET or citronella
candles because of kids) to the bug problem for a small apartment
backyard (surrounded by yards all around. There are many, many bugs.

If anyone has experience (positive or negative) with Thai lemon grass
(Cymbopogon citratus), catnip or marigolds
whether it grows outside in NYC (Brooklyn), potted or planted
he yard is small 10 x 16
how many plants to be effective
shade or sun
can I plant in the ground now?

or maybe any other plants like insectovores (i've seen some very small
ones for sale at Lowe's)
