What I'm reading says the bright red "apple" ball attracts the apple maggot fly... Maybe I could use this https://www.amazon.ca/Ortho-Tanglefo...s%2C102&sr=8-9 although the price is a little steep but 1 can is over $90!!.. and maybe I could get some fruit fly traps like this https://www.amazon.ca/dp/B07HP94VCP/...s_B07SFK79TJ_0 to spray and hang on the tree. Don't really have any other options that I can think of....
