Does growing in a green house protect at all from bugs?

I want to know your opinions on growing in a green house to protect from bugs.
Does it help keep the moths away that lay eggs that turn into the bud worms?
I plan on doing next years out door in a small green house and plan on using a bug zapper outside the green house to try and kill the moths. I always use safer brand caterpillar killer, but it seems real questionable if it even helps. I hate bud works more than anything else about OD growing. I always get so over run with them.

if its fully sealed should keep all bugs out unless you keep the door open

Nice, that's what I was hoping to hear.

I keep a very healthy population of paper wasps in the eaves of the shed next to the garden, they keep caterpillars and grasshoppers down.
Of course, not recommended if you're allergic or have children.

Screen all openings. ie, doors, windows, intake and exhaust fans and the like.

It will reduce the amount of bugs, but will increase your ambient temps and will increase humidity. This may increase the chances of moldy or mildewed bud. You will need to have excellent ventilation and an ability to shade.

Completely enclosing it brings its own issues. 1st time I tried was more for stealth but for worms as well. Instead I had a major aphid infestation, only time I had that issue. Still not as bad as bud worms but the following year we replaced the plastic walls with screen & ran more fans, that worked much better. Good ventilation is a major key.

I don’t live in that house anymore but I am still fighting those worms big time, thinking of doing a pollination cage next year, all netting so good ventilation. Thinking of a PVC hoop frame covered with net.
