dude, there's an option called debug in the pause menu that rests the spawns, but they tend to get stuck again rather fast, so do it in the area where you want to hunt for things. Mites spawn in dead grass "biomes", wold spiders by the oak tress, especially under it, and by the flat rocks in the south east. lady bugs spawn between the Koi pond and the oak tree, grubs spawn around the tree, and larvae by the water, around the marshes near clay deposits. they also spawn by the berry hedge, near the power plug. Koi fish get stuck under the map sometimes and you need to debug respawn them, which is once per save load, so save and load if you need to do it again.
