So something is eating your milkweed plant and it's not a Caterpillar?

FIRST OF ALL Important Note:
Don’t use insecticides or pesticides on milkweed, they can kill monarch eggs, caterpillars, or pollinators!
Common Pests That Damage Milkweed:
1. Aphids (especially Oleander Aphids)
Tiny yellow/orange insects with black legs
Suck the sap from stems and leaves, weakening the plant
Often found in big clusters on new growth
Solution: Spray with water, introduce ladybugs, or wipe off gently
STORY TIME: I had to spray with water, wipe off gently + buy ladybugs to help eat the Aphids!
See my instagram for my post on the ladybugs I bought:)
2. Milkweed Beetles (Tetraopes spp.)
Red with black spots, long antennae
Chew on leaves and stems
Not usually a huge problem unless there’s a large infestation
3. Milkweed Bugs (Large and Small Milkweed Bugs)
Orange/red with black markings
Feed on seeds and seed pods, not leaves — so less damaging to caterpillars but can reduce future plant growth
Solution: Hand-pick or remove seed pods if needed
4. Spider Mites
Super tiny, hard to see without magnification
Cause stippling (tiny yellow dots) and leaf curling
Thrive in hot, dry weather
Solution: Hose them off, increase humidity, or use insecticidal soap
5. Slugs & Snails
Feed on tender young leaves or seedlings
Solution: Use crushed eggshells or copper tape as a barrier
STORY TIME: This is also something we did, we crushed up some eggshells- Rinse your eggshells well– Remove any egg residue to prevent attracting unwanted pests or odors.
Let them dry completely– Air-dry or bake them for a few minutes at low heat (optional, but helps make them brittle).
Crush the eggshells finely– Use your hands, a rolling pin, or a food processor to break them into small, sharp bits — not powder, but not big chunks either.
Sprinkle a ring around your milkweed– Create a barrier circle around the base of each plant.– Slugs and snails hate crawling over the sharp, jagged surface.
Reapply as needed– After heavy rain or watering, refresh the ring to keep it effective.
