The aphid often is just one of multiple insect species that weakens a milkweed plant during a season. A species of parasitic wasp has been approved and introduced that feeds specifically on this aphid but it is currently not being sold by any company in North America. The wasp is not widespread as a result of the introduction. Certain other species parasitic wasps that feed on aphids have been observed to sometimes feed on the oleander aphid.

Highway expansions have been a source of destruction for the plant and its habitat. In 2019, this issue came to the fore again. A highway expansion will destroy some of the plant's remaining habitat, so ecologists are trying to move the plants, a practice that has, so far, not been effective.
