Certified ExpertA.Here is a good explanation of "oils."
https://extension.unr.edu/publication.aspx?PubID=3029
White oil generally refers to mineral oil but can refer to an insecticide used to smother insects such as aphids, scale, mealybugs, and mites. It is not the same as Neem Oil but both can smother insects. Horticultural oils are generally petroleum based whereas Neem oil is plant based.

I never hear of anyone using white oil so I would recommend Neem oil.

Certified ExpertA.If you are having heavy infestations of bagworms you may want to apply the pesticide every week for four weeks beginning in late May, according to a Kansas extension publication. The Ohio publication mentions two applications, because they don't all hatch at once, but the second one is soon after the first application. The Nebraska publication also mentions two applications - one in mid June and again in early July for best control.
So it is up to you. If you are achieving control with one application, stay with it. If you aren't seeing any bags, you can skip a year. A few bags won't defoliate a tree, but it does leave the possibility of more than 1,000 eggs left for next year. Here is lots of info about bagworms. :)

Certified ExpertA.Florida extension says they are difficult to kill with pesticides because of their ability to fly away. It suggests contacting your local extension office for the latest pesticide to use. It also suggests shaking a tree branch over an open umbrella, then dropping them in soapy water. Here is how to contact them:

AustraliaQ.Can I Use Jar Garlic To Make Garlic Spray To Deter Grasshoppers? Or Do I Have To Use Fresh Garlic?
I have a plague of grasshoppers in my relatively new garden I need to get deter. I don't want to harm them, but they have destroyed nearly everything I have planted since moving in. Citrus and stone fruit, pelargoniums, passionfruit, geraniums, buddleia, heliotrope - you name it, they've completely defoliated it. There are so many of them I feel like it's going to take a long time to move them along. If I do end up spending weeks making batches of garlic spray, it would be convenient to just spoon it out of a jar. I'm also trying to attract lizards and birds to predate on them naturally, but the yard I bought was completely barren, so it will take a while for the trees and micro-habitats to become established.

Certified ExpertA.Jarred or pickled garlic should be just fine if it still has its pungent smell. These articles will help:
