Post bagging to stop apple maggot
I read about using plastic sandwich bags to prevent apple maggot and codling moth. Has anyone tried this method, if so was it successful?

Post bagging apples
Yes, I have used the ziplock sandwich bags for several years now. They are
the best methog I have found for covering fruit. Although they are not
inpervious to apple maggot or codling moth attack, they keep out all but the
most determined insects from entering. I may try the plain sandwich bags
next year with twist ties, because some insects enter the zip lock bags at
the stem where the closure is not tight.


I have also tried footsies this year and will not use them again. First of all,
they deteriorate in the outdoors over time. They can stetch out leaving big
openings for bugs to enter. They did much more poorly in protecting my
apples from codling moth and apple maggot than the zip lock bags. The other disadvantage is that if the apple falls to the ground, the rabbits and
squirrels have no problem getting at a footsie covered fruit. They tend to
keep away from the zip lock covered apples. I have actually added the
zip lock bags over the footsies for added protection. The footsies appear to not doing the job, and I can't recommend them.

Do you vent the plastic bags somehow so they don't fill with rain water and cause the apples to spoil? I thought about using the fold-lock sandwich bags with one of those hand grip staplers to fasten them around the apple stem but was concerned about the water issue.

I did provide two drainage holes at opposite sides of the bottom of the zip
lock bags. They still need a little attention, as sometimes they get blocked
up with debris.

I'm not sure if there is a major problem of bugs entering the ziplock bags
at the stems of the fruit. It may be more secure to used a non-ziplock bag
and use twist ties for closure, but it will take a bit longer to attach these vs.
the zip lock bags. I think that the thickness of the plastic bag may be a factor, as I have seen a few cases where the bug penetrated through the
bag into the fruit directly opposite the entry point. However, as I stated
earlier, the footsies were more prone to this kind of entry. I may try
experimenting next season with both the ziplocks and twist tie coverings.
I may also have to return to limited spraying as the coverings did not protect all of the fruit. The longer the fruit is on the tree, the more susceptable it is to penetration. Also, the codling moths and/or apple maggots have their favorite varieties. They went for the more aromatic apples and left my Williams Pride pretty much alone. At worst, I have
had about 25% of my apples attacked, even with bags on them. No more
footsies for me.
