bugs in native soil

so i will be starting a grow of about 4-6 plants outdoors this weekend i buying clone's tomorrow put them in party cups for a week or two while hardening them off to stay outside

the spot i choose is about 3x10 and i will be adding a bag or two of ffof to the native soil

anyway last night i went out to turn the soil that i will be planting in and noticed a bunch of ladybugs Rollie pollie's and spider's

i assume that these are all predatory insects that will eat the bad bugs

but if there in there then they must have stuff for them to be eating right?

what can i do to the dirt before i plant them too avoid bugs ruining everything

If you want you could soak the dirt with sum neem oil but I wouldnt even bother if there are other native plants growing just fine in the area.
