We have a Concord (?) pear, which can produce very tasty, juicy fruit

The last 3-4 years, as the fruit begins to ripen, wasps start eating the

Any suggestions for preventing the little black and yellow ^&%*£!! from
doing this.

You just have to pick them just before they are ripe.

The wasps start on them well before that, sometimes when they are only
half grown .....
