You won’t be getting less arthropods. Only a lower diversity of them.
For example. Most people in my city do it like the above. And 93% of the houses still have highly venomous Gaucho spiders. On the other hand since I’m trying to have a garden like the below, my garden has less of them but more of completely harmless stuff - garden spiders, native bees, crickets, butterflies, and the likes.
I guess OP enjoy swarmed by bugs and spiders
