The top priority for many gardeners is keeping their garden safe from pests. It’s something most, if not all, gardeners can relate to. There are many methods and techniques for pest control, but some only work on specific pests, while others aren’t very accessible. Beneficial insects, like ladybugs, that eat pest insects can save you a lot of time and effort, but knowing which ones eat the pest that’s troubling you can be tricky. Luckily, we’re here to help. Here’s everything you need to know about spider mite pest control and how ladybugs can help.
Spider mites are tiny pests that can cause quite a bit of damage. True to their name, they’re arachnids, although they look more like insects than spiders. Spider mites enjoy many plants, including fruit trees, berry bushes, vines, and even some ornamental houseplants. In small numbers, they’re a nuisance, but warm weather with little to no wind causes an increase in population that can be devastating. This means spider mites, while existing in almost every state, are particularly troublesome for southern and southwestern states.
Due to their small size, spider mites can be difficult to spot. Instead, check your plants regularly for signs of damage. Spider mites drink the fluids from leaves, which results in lots of small light dots, called stippling, on them. In a healthy plant, this stippling won’t have any real effect. However, in young, weak plants, it hinders photosynthesis, weakening the plant further. Leaves that are stippled may also begin to brown and curl at the edges.
In severe infestations, you may notice small webs, similar to what a spider might leave. These webs most commonly appear when a sizable population of spider mites is present. Spider mites reproduce quickly, so by the time the population reaches such sizes, it’s difficult to control. This makes spotting the early signs all the more important.
Yes, ladybugs do eat spider mites, along with several other small pests. Ladybugs can be a great asset for pest control, since they’re voracious eaters and don’t damage plants. If you don’t have ladybugs already in your garden, you have two options. You can either get ladybugs from a specialty store and release them into your garden or lure in ladybugs from the surrounding area.
Luring ladybugs to your garden shouldn’t be too difficult if you already have spider mites in your garden. Ladybugs, like all animals, will go where there is food. However, ladybugs also eat pollen and flower nectar when there aren’t enough pests for them to eat. You can encourage ladybugs to move into your garden by planting some of their favorites, including dill, cilantro, cosmos, and tansy.
Planting these flowers can also be helpful if you plan on releasing ladybugs. This is because one of the two main issues with releasing ladybugs into a garden is that they simply might not stay there. Making sure they have plenty of food sources and a water source, releasing them near the plants with the heaviest infestation, and releasing them at night can significantly increase the odds that they’ll stay. The other main issue with releasing ladybugs is that if the ladybugs have been improperly caught, bred, or raised, then they may have diseases which could pass to any wild ladybugs in your area. Getting your ladybugs from a reputable brand or specialty store helps ensure that you get healthy ladybugs.
Spider mites are soft-bodied pests, which makes them fairly easy to deal with as long as you know where they are. Insecticidal soaps, which are made from potassium salts of fatty acids, are a common method. You can find them in most gardening and lawn care stores, or make your own from vegetable oil and a natural, bleach-free soap. Neem oil is another natural pest control method that works on spider mites. It’s made from the neem tree, also called Indian lilac. The neem tree is a relative of mahogany native to India and most countries in Africa.
Since spider mites are so small, they can also be blown off with water or air. A water hose can be used to knock spider mites and their eggs off of plants. Adjust the water pressure and test it before spraying to avoid spraying too hard and harming the plant. Additionally, this method isn’t ideal for delicate plants or those that hate wet leaves, like succulents.
Spider mites are obnoxious little pests, but with these tips, they don’t have to be. It’s best to act quickly to avoid them establishing a permanent home on your plants, so keep a keen eye out for stippling. Luring ladybugs to your garden can be a great preventative measure, and releasing ladybugs or spraying your plants with insecticidal soap, neem oil, or even just your water hose can keep them at bay if they’re already present.
