I’m on the monarch migration path and had wild milkweeds with monarch butterflies for a few years but the last 2-3 years oleander aphids exploded in population and I’ve seen a single caterpillar since.
Are there ways to mitigate that while not killing the monarchs or am I just shit out of luck?
I release ladybugs every year and that seems to help. You can buy them online if they are hard to find locally.

The ones available online are from the western U.S.; depending on where you live, that may be counterproductive to the locally native species that are struggling.

Grow some yarrow, dill, or sunflowers and get ladybugs to lay their eggs all over your garden naturally, and I imagine you'll start to see much better results! Larval stage ladybugs are significantly more ravenous than their adult forms.

A lot comes up when you search for the BluMorpho tags. Some random links:

Looks like there is an app you can download too that can do stuff like scanning for tags nearby.
