1. Plant lots of palm trees
- this should be obvious and you’ve probably already done this step
2. Remove all flowers
- butterflies won’t spawn after this however if you are so inclined they don’t spawn around hibiscus shrubs so you can leave them
3. Cut down all deciduous trees and remove all stumps
- leave as few trees as you’d like if you want to catch scarab beetles, rainbow stags and giant stags
- if you do leave some, actively scare away cheap bugs as soon as you see them!
That should be a general rule. There’s a limit to the number of bugs on the island so scare off the cheap bugs actively. That way you force the game to respawn more bugs (which are hopefully big beetles).
So good so far… but what about stuff like wharf roaches, tiger beetles, locusts, and hermit crabs? Well remember, if you don’t give them a place to spawn they won’t spawn
Just litter crap all over every walkable tile on your island. Bugs can only spawn on empty spaces. I’m working on getting the beach covered too but I’m going p casually about it (ie each day just throw coconuts and shells into the center). In a pinch you can dig holes but they don’t stay on the island and you can’t walk through them (duh).
The way the algorithm works it seems that bugs tend to spawn in the same place so if you walk around and a roach has appeared onscreen, just drop an item on that spot. I dunno if covering every single tile will mean no more ground bugs but in either case, if you see them, chase them into the water.
In my experience this made beetle hunting go so much faster that I rarely circle the beach more than once before seeing something worth catching (whereas before I’d be lapping the beach constantly). God knows I should spend more time working IRL to earn actual money rather than bells T w T. Anyway, hope this helps and saves you some time.
