Spider mites in gardens are frequently eliminated by ladybugs. They can provide a lasting solution to the issue with the right quantity of patience. Spider mites are consumed by other predators like ladybugs, spined soldier bugs, and lacewing larvae.

Do Ladybugs Eat Spider Mites?

Ladybugs do indeed consume spider mites. Since they are voracious eaters and don't harm plants, ladybugs can be a great help in pest control. There are two things you can do if ladybugs aren't already present in your garden. You have two options for attracting ladybugs: either buy them from a specialized retailer and release them into your garden, or use lures to attract them naturally.

If your garden already has spider mites, luring ladybugs there shouldn't be too challenging. Like all animals, ladybugs will seek out food. When there aren't enough pests to eat, ladybugs will also consume pollen and flower nectar. Planting some of the plants that ladybugs like, like dill, cilantro, cosmos, and tansy, will entice them to come to your garden.

If you intend to release ladybugs, planting these flowers can be helpful as well. This is due to the possibility that ladybugs released into a garden may not remain there, which is one of the two main problems. Making sure they have plenty of food and a water source, releasing them close to plants with the worst mite infestation, and releasing them at night can all greatly improve the likelihood that they'll stay.

The other main problem with releasing ladybugs is that if they have been caught, bred, or raised incorrectly, they might have diseases that they could spread to any wild ladybugs in your area. If you purchase your ladybugs from a reputable company or specialty retailer, you can be sure that they are healthy and won't unintentionally endanger the ladybugs that already exist in your neighborhood.

How to Get Ladybugs to Eat Spider Mites?

You can either buy some ladybugs or lure them to your garden if you're interested in having them in your garden.

Luring Ladybugs

Make sure your garden has food for ladybugs to draw them. Of course, the spider mites already provide food for them, but you can also add any flowers that attract pollinators or flower nectar.

Your favorite food plants should be planted. This could be cilantro, cosmos, tansy, or dill. Providing them with a permanent home in your garden by growing the plants they like will entice them there and keep pests at bay.

Buying Ladybugs

Ladybugs can be purchased in bulk from specialized plant stores and online retailers like Amazon. In order to purchase them and plant them in your garden.

When you release these ladybugs, it is crucial that you provide them with food and water. You will need flowers and plants like cilantro or dill for the same purpose as luring ladybugs.

So that your purchase does not go to waste, these plants will keep ladybugs in your garden for a long time.

But bought ladybugs might have been bred incorrectly. This could cause additional problems, such as sick or diseased ladybugs. This could endanger the local bugs and ladybugs in your garden and cause further issues.

It's crucial to do your homework on the supplier of the ladybugs. It will be easier to buy ladybugs if you find a reputable retailer with lots of positive reviews.

5 Reasons Ladybirds Should Not Be Used to Control Spider Mite

Here are a 5 key reasons why adult Ladybirds should not be used in an attempt to control Spider Mite infestations:

1. Spider Mites are not the Ladybird's preferred food source

Although Ladybirds may eat a small number of these pests, they are not their preferred food source. Accordingly, ladybirds won't gorge themselves on spider mites and are much more likely to flee in search of a more palatable food source.

2. Spider Mite populations increase too quickly for Ladybirds

It can take a ladybird several weeks to complete its life cycle from egg to adult. Populations of spider mites can multiply tenfold in just 10 days and can double in less than 3 days. There can be no control because of the complete imbalance between the slow population growth of ladybirds and the rapid population growth of spider mites.

3. Ladybirds will not eat enough Spider Mites to quell infestations

Ladybirds will not eat enough Spider Mites. When combined with the ladybirds' lack of interest in spider mite as a food source, pest populations can grow quickly. This is because spider mite infestations are a problem that is increasing in population quickly.

4. Ladybirds are too sensitive to temperature and light conditions

Ladybirds are sensitive to temperature and day length so may go into hibernation or choose to migrate under certain conditions. For example, during the winter, plants may grow indoors or in heated greenhouses.

5. Consistent Ladybird application will be an expensive commitment

When compared to specifically bred Spider Mite predators, ladybirds are a very expensive investment. When we look at the number of spider mites eaten by each predator, this is especially clear. Phytoseiulus persimilis predators, for example, will consume up to 5 adult Twenty eggs or young spider mites per day!

By releasing ladybugs in your garden, you can quickly and efficiently combat a spider mite infestation there. The spider mite population will be controlled thanks to this. Most garden centers and nurseries sell ladybugs that are prepared for release around cannabis plants. If you want to ensure that your population adapts well to their new environment, be sure to follow the suggestions that are listed below:

  • Utilize a large number

Despite the fact that a single ladybug can consume a large number of spider mites, you must release a large number of them at once to complete the task. The number of spider mites is increasing quickly, and some ladybugs may die or disappear as a result.

  • Early morning/evening release

The best time to release ladybugs is early in the morning or early in the evening because they don't like the heat. There is a good chance that they will fly away to find a cooler place to rest if you let them out in the middle of the day. There is a higher likelihood that they will stay in the area if you release them at the right time.

  • A fine mist should be sprayed over your plants

Put a layer of moisture on top of your plants to encourage creatures that are beneficial to your garden to settle in and stay.

What Does An Infestation of Spider Mites Look Like?

Due to their small size, spider mites cannot be seen by the human eye, unlike larger pests like squash bugs and June bugs.

They prefer to hide where there is cover from the leaves.


Spider mites come in many different varieties, and each has its own distinctive coloration and pattern. You would need a microscope to see that much detail, though.

Small, dark brown or "burnt" patches on the leaf surface are a telltale sign of the early stages of an infestation caused by spider mites. In the early stages of a spider mite infestation, these spots can be seen. The bug that caused these small charred patches can currently be found by swiping them with soft tissue. You should be able to see tiny streaks of mite blood if it is caused by mites.

The eggs will then materialize after that. These are rather tiny, transparent, and spherical in shape.

Spider mites create a sticky, thin, and dense web. This web serves to protect the eggs of the spider mites and can quickly cover the entire plant. Because of this, your plant won't get enough sunlight and won't be able to breathe or transpire properly. It is not advised to wait until the illness has progressed this far, though.
