Read this article to learn how you can tackle this menace in your garden. With our expert tips, you can get rid of these bugs and prevent them from coming back once and for all.

How To Get Rid of Milkweed Bugs

Get rid of milkweed bugs by washing the plant thoroughly, immediately isolating it, and removing the infested leaves. These bugs are tropical and feed on the sap of the plant leaves, so it is important to fix this problem before it becomes worse.

Continue reading for in-depth details on how you can tackle them before they end up weakening your plant.

– Act Quickly

As soon as you spot these pests, act immediately and take charge before they spread and damage the plant. The more you delay treatment, the more they will weaken the plant by ingesting the sap from the leaves.

– Isolate the Plant

You need to prevent the spread of spider mites by isolating the plant. Quarantine it in a separate area so that other plants around it don’t get affected as well.

– Remove Infested Leaves

Snip away all those sections of leaf foliage that have been heavily infested. Do not mix the infested leaf with other garden trash. Instead, seal them in a plastic bag before disposing of them to prevent further spread.

– Give the Plant a Thorough Wash

The easiest way to get the mites off the plants is to wash them off. Spray the plant completely with water. Pay especially close attention to the under-surface of leaves where the mites predominantly thrive and lay eggs.

– Use an Alcohol Mixture

Clean the plant with a mixture of alcohol and water. Apply directly over all spider mites and leave them on for a few minutes before wiping them off with a lightly damp towel.

– Remove the Layer of Mulch

If you have a layer of mulch or humus at the base of your plant, you will need to remove it. Mulch serves as a perfect destination for the bugs to hide and thrive, even after a wash. Thus, clear them away by digging out an inch of the soil.

– Use a Pesticide

Diatomaceous earth is a mineral pesticide that proves beneficial in removing spider mites. It kills the pests permanently from the plant by dehydrating them.

– Get Bugs as Allies

Ladybugs, lacewing, predatory mites and bugs are natural predators. They can prove to be quite handy in getting rid of spider mites. They feed on the mites, with the capability of removing over five thousand mites at one go.

You don’t need to worry about them being around as they do not cause any harm to the milkweed plant. Remember, bugs work as perfect allies when the pest infestation level is still low to medium.

– Use Soapy Water

Another interesting way to get rid of these milkweed insects is to use soapy water. Make a mixture with dishwashing soap and water.

With the help of a spray bottle, apply directly to the milkweed beetles. It will prove to be an easy and effective way to make these pests fall off the plant.

– Manual Removal

In case there aren’t many bugs on milkweed, you can pick them off manually. Wear protective gloves and scoop them off the plant, provided you are sure that there are only a few of them there.

– Sanitize the Area

Sanitize the area around the plant to prevent further infestations. Change the potting mixture, wash the surface and inspect the plant well before you replant it elsewhere.


Kill Spider Mites Organically

Get rid of spider mites organically with the use of essential oils and sprays. With their strong natural smell, they are a chemical-free way to tackle bugs. The beetles get repelled by the natural smell of these products. Here is a list of organic sprays for direct application on the pests.

– Essential Oils

A few essential oils you can use are listed below. A point to note here is that essential oils tend to burn the plant. Before you go ahead with this, test a portion of the plant with it first.

  • Neem oil
  • Lavender
  • Peppermint
  • Tea tree oil

– Natural Garlic Spray

Garlic is an amazing ingredient to combat pests. You can make a natural garlic spray by mixing four crushed garlic pods with liquid soap and water. With the help of a spray bottle, spray liberally on the area of pest infestation to effectively and organically get rid of the mites.

– Cayenne Pepper Spray

Another organic spray that can be used is cayenne pepper. Make a mixture of one teaspoon of cayenne pepper with water and spray the solution all over the plant to control the spread of mites.

Identifying Spider Mites on Milkweed

The first thing to do before you even get started on tackling the menace is to learn to correctly identify the pests. In this section, we list out the distinctive visual features of a spider mite infestation on milkweed plants.

  • Spider mites are white or light green bugs.
  • The mites weave fine silk webs, especially on leaf undersurfaces.
  • They have an elongated, oval-shaped body of around 0.4 mm in length.
  • Nymphs look similar to adults but do not have fully-grown wings.
  • Infested plants develop discolored leaves with a white and leathery texture.
  • Further signs of infestation are curled or burned leaf edges.
  • You will most likely spot them around the summer months.
  • Another infestation sign is black eggs on milkweed leaves.

How To Prevent 

Misting the plant, removing litter, and regular pruning can help prevent insects from attacking a milkweed plant. Aside from these, you can avoid milkweed bugs by taking a few more easy preventive measures. Read on for the details.

– Provide the Right Environment

Spider mites thrive in dry, dusty and hot environments. Thus, keeping your plant away from heat and dust can reduce the problem considerably.

Move the plant into the shade and provide a greenhouse effect so that these plants remain cool. Keep the plant well-hydrated as well.

Removing Spider mite from milkweed

– Mist the Plant

Settled dust will increase the chances of mites. Prevent dust by misting the plant regularly, paying close attention especially under the leaves. If you spot dust, gently wipe it with a moist cloth.

– Remove Leaf Litter

Clear leaf and twig litter especially after the fall season. The litter promotes the breeding of these pests.

– Prune Regularly

Pruning regularly keeps pests at bay. It is a good practice that essentially keeps the garden healthy and fresh.

Pruning can stop pest infestation in large numbers. The spider mites won’t be able to latch on in clusters around any specific spot of the plant, so by regularly pruning and removing extra foliage, you can prevent all other bugs and beetles as well.

– Space the Plants Out

Plant milkweed plants away from each other by keeping a space of about 10 to 20 inches between them. By spreading the plants out, one infected plant will not be able to infect another.

– Limit Their Food Source

Spider mites ingest the sap of milkweed leaves, but they also feed on other insect larvae. Limit the occurrences of these food sources. With limited food, the insects will not be able to multiply to create a large population infestation.

– Use Essential Oils

Essential natural oils such as neem oil can repel insects with their smell. Thus, the mites will not be able to create colonies in your plant. The ideal time to spray neem oil will be during the spring and summer seasons, once every two weeks.

– Maintain a Proper Watering Schedule

As mentioned earlier, spider mites thrive in dry conditions, so make sure that your plant is well hydrated and watered regularly.

– Maintain Moisture

Try to make the air humidity around the plant higher. Spider mites will not be able to thrive in humid conditions.

– Use High-quality Potting Soil

Potting soil such as Sterlite can be used to avoid not only spider mites but also other soil-borne pests.

– Inspect Plants Regularly

As they say, prevention is better than cure. Therefore, inspect your plants regularly to catch the appearance of spider mites early. Check for dry soil conditions, nutrition and brown spots. Address the needs of the plant to prevent any pest infestations.
