Deer and rabbits have been reported to eat milkweed leaves, and there are many other insects that feed on milkweed such as milkweed bugs, tussock moths, queen butterfly larvae, and more. Nectar and pollen from milkweeds are important food sources for many pollinators, in addition to monarch butterflies.
Brush the bugs aside with a detail brush to get rid of them. Use a spray bottle filled with water and a couple tablespoons of mild dish soap to remove the insects. Soapy water usually does the trick quite nicely. If there aren’t very many bugs on your milkweed plant, you could try to pick them off manually.
Additionally, how do I get rid of aphids on milkweed without harming caterpillars? A mild solution of dish soap and water can also be used to kill aphids on milkweed plants (again, after monarchs have been removed). Spraying this solution directly onto the aphids effectively kills the insects.

Do slugs eat milkweed?
Slug Problems While resistant to disease, milkweed does attract slugs. These slow-moving, leaf-eating garden pests damage leaves and flowers when given a chance. As you pick off the slugs, drop them in the bucket. The soap kills the slugs, eliminating the unpleasant task of crushing them.
Are milkweed tussock moths bad?
The adult Tussock Moth has a unique defense against bats, one of its main predators. Instead of tasting bad like many moths and butterflies, the moth imitates high pitched clicking sounds used by other bitter tasting moths.
Are milkweed tussock moths harmful?
The Milkweed plant sap that the moth feeds on contains a toxic chemical called cardenolide and it accumulates in the body of whatever eats it. Monarch butterflies, Milkweed Bugs, and this moth are prime examples of insects that benefit from this toxicity. Adults are active from late spring to early autumn.
Where do milkweed bugs come from?
Large milkweed bug. Oncopeltus fasciatus, known as the large milkweed bug, is a medium-sized hemipteran (true bug) of the family Lygaeidae. It is distributed throughout North America. It ranges from Central America through Mexico and the Caribbean to southern areas in Canada.
What are the orange and black bugs on my milkweed?
The large milkweed bug, Oncopeltus fasciatus, is colored orange-red and black. It has a long proboscis and is a piercing sucking insect. It feeds on the seeds, leaves and stems of milkweed (Asclepias). The bodies of milkweed bugs contain toxic compounds derived from the sap which they suck from milkweed.
What is the life cycle of a milkweed bug?
Milkweed bugs go through simple metamorphosis. This life process has three stages: egg, nymph and adult. A milkweed bug’s body changes form three times during simple metamorphosis. The milkweed bug’s life begins on a milkweed plant.
What eats a milkweed bug?
Small (common) milkweed bugs are mostly herbivorous, but can occasionally be scavengers. These insects have been reported feeding on a wide variety of other insects, such as honey bees, monarch caterpillars and pupae, and dogbane beetles.
What are the yellow bugs on my milkweed?
The bright yellow aphids found on milkweeds are destructive, non-native pests. Natural controls for the pests, sometimes called oleander aphids, include the ladybug, especially in the larval stage, as well as the lacewing, syrphid fly larvae and the tiny wasp Lysiphlebus testaceipes.
Are milkweed bugs harmful to humans?
Similar to the Monarch butterfly, the Large Milkweed Bug protects itself by consuming milkweed sap–which is toxic to most predators. For the most part, these bugs aren’t dangerous. They don’t bite or sting, nor do they cause any real damage to the plant.
How do you protect monarch caterpillars?
Avoid touching your eyes and wash your hands after handling milkweed. To keep the milkweed from drying out, keep eggs (on the milkweed on which you collected them) in a container lined with a moist paper towel. Monarch caterpillars can be kept in an aquarium, large jar, bug cage, or other roomy containers.
Where did all my monarch caterpillars go?
If disappearing caterpillars are 5th instar caterpillars, odds are they moved away from your milkweeds to find a safe place to form their chrysalis (they typically do not pupate on milkweed plants). If earlier instars or eggs are disappearing, a more likely culprit is a monarch predator.
What percentage of monarch caterpillars survive?
Yes, the percentage of monarchs that survive from egg to adulthood is very low. Researchers agree that less than 10% of the eggs that are laid survive to become adult butterflies, and some feel that this number may be significantly under 10%.
Why do monarch caterpillars leave the milkweed?
Well, this is another reason that milkweed is so important to monarchs. Monarchs become toxic to predators by storing toxins from the milkweed plants that they ate during their caterpillar stage. Milkweed contains toxins called cardenolides which can be harmful to predators and also make monarchs distasteful.
Do Monarch caterpillars eat each other?
It turns out that monarch caterpillars can be cannibals. They are very hungry, especially after the 3rd instar, so if food is scarce they will eat each other.
Do Daddy Long Legs eat monarch caterpillars?
They prey on insects and caterpillars. A daddy longlegs cleans up plant and animal debris, eats small insects and drinks plant juices. A couple years ago we started raising monarch butterflies at our house – providing a safe place for the larvae to mature.
