Plant lice can be a real nuisance, but don't worry, I've got some great news for you. Getting rid of them naturally is definitely possible.
First, let's talk about what plant lice are. They're tiny insects that feed on plant sap, causing curled or distorted leaves and stunted growth. This can be especially frustrating if you're trying to grow a specific type of plant.
To get rid of plant lice, you'll want to use a combination of methods that target the insects and their eggs. One effective approach is to use neem oil, which can be applied directly to the affected areas of the plant.
Removing Aphids
Aphids can be a real nuisance in the garden, but there are several ways to get rid of them naturally.
One of the most effective ways to remove aphids is to use a strong spray of water to knock them off your plants. This method is easy and inexpensive, and it's also a great way to rinse off the "honeydew" they leave behind, which can attract ants.
You can also use a twig, tissue, or implement to remove aphids manually, especially for small colonies. Alternatively, grab the hose pipe and spray them from your plants with a strong stream of water. A hose-end sprayer attached to the end of your hose pipe might work a little better.
Aphids have weak legs, so most of them will be unable to crawl back up the plants to feed after being sprayed with water. You can repeat this process every few days as needed until the population is visibly reduced.
If you prefer not to use water, you can try removing aphids by hand. Put on some garden gloves and knock them off of stems, leaves, flower buds, or wherever you see them, and into a bucket of soapy water to kill them.
Some other natural aphid treatments include insecticidal soap, neem oil spray, and neem oil concentrate. These can be sprayed directly on the aphids to kill them.

Natural Control Methods
Aphids are a common problem in gardens, but the good news is that there are natural control methods that can help get rid of them without harming the environment or your plants.
You can start by growing young plants under row covers, which will prevent aphids from reaching them. Remove the covers when the plants begin to flower, as aphids are less likely to be attracted to blooming plants.
Using aluminum foil or reflective mulch on the ground beneath the plants can also be an effective deterrent. This method is particularly useful in vegetable gardens.
Some plants, such as nasturtium, aster, and mum, are actually attractive to aphids. You can use these plants as a trap crop by growing them far from your garden, which will lure the aphids away and keep your garden aphid-free.
Here are some plants that are known to repel aphids:
- Nasturtium
- Aster
- Mum
- Cosmos
- Hollyhock
- Larkspur
- Tuberous begonia
- Verbena
- Dahlia
- Zinnia
Another option is to plant garlic or onions near infested plants, as the smell of these plants will drive aphids away.
Organic Aphid Control
Growing young plants under row covers is a simple and effective way to prevent aphids from reaching them. Remember to remove the covers when the plants begin to flower.
You can also use aluminum foil or reflective mulch on the ground beneath the plants to deter aphids. Reflective mulch in the vegetable garden is a very effective deterrent.
Some plants are actually attractive to aphids and can be used as a trap crop by growing them far from your garden. These plants include nasturtium, aster, mum, cosmos, hollyhock, larkspur, tuberous begonia, verbena, dahlia, and zinnia.
Planting garlic or onions near infested plants can also help to drive aphids away with their smell.
Using insecticidal soap is another effective way to kill aphids. You can make your own insecticidal soap at home with this recipe: mix one cup of vegetable oil or a pint of water with two teaspoons of dish soap.

A strong spray of water can also knock aphids off your plants. This method is easy and inexpensive, and can be repeated every few days as needed until the population is visibly reduced.
Another natural remedy for getting rid of aphids is neem oil. The organic compounds in neem oil act as a repellent for aphids and other insects, and can be used to control different types of fungus.
Diatomaceous earth, a fine white powder made from fossilized remains of tiny aquatic organisms, can also be used to kill aphids. It works by cutting through the waxy outer layer of an insect's body, causing fatal dehydration.
Here are some natural predators that can help control aphid populations:
- Ladybugs
- Green lacewings
- Yarrow
- Wild buckwheat
- White sweet clover
- Tansy
- Sweet fennel
- Sweet alyssum
- Spearmint
- Queen Anne's lace
- Hairy vetch
- Flowering buckwheat
- Crimson clover
- Cowpeas
- Common knotweed
- Caraway
These plants can be grown in your garden to attract these beneficial insects and help control aphid populations.
Keep Healthy
Keeping your plants healthy is key to preventing aphid problems. Healthy plants are better equipped to fight off pests, and that's a fact.
Reduce aphid-attracting plants to minimize the population. This means removing any plants that might be drawing in aphids.
Maintain plant health by providing adequate nutrients, water, and sunlight. This will help your plants grow strong and resilient.
Don't over-fertilize your plants, as this can make them more susceptible to pests. A balanced diet is what they need to stay healthy.
Manual and Trapping Methods
Manual and Trapping Methods can be a simple and effective way to get rid of plant lice naturally.
You can manually remove aphids by using a twig, tissue, or other tool to physically remove them from small colonies on your plants. Alternatively, grab the hose pipe and spray them off with a strong stream of water.
Using a hose-end sprayer can make the process even more efficient. This is a much better option than reaching for chemical solutions.
Planting a trap crop is another effective method. A trap crop is a sacrificial plant that attracts aphids, keeping them away from your more valuable plants. Good trap crops for aphids include nasturtiums, calendula, and nettles.
Here are some plants that are attractive to aphids and can be used as a trap crop:
- Nasturtium
- Aster
- Mum
- Cosmos
- Hollyhock
- Larkspur
- Tuberous begonia
- Verbena
- Dahlia
- Zinnia
Plant these trap crops around the perimeter of your garden early in the season, and they will help keep aphids away from your main crops.
Manual Aphid Removal
Manual aphid removal is a simple and effective way to get rid of these pesky pests. Use a twig, tissue, or implement to remove them physically from small aphid colonies. A strong stream of water from a hose pipe is also a great option to knock them off your plants.
You can use a hose-end sprayer for better results. This is a much better option than reaching for chemical solutions. A strong blast of water will knock most aphids off the plants, and the weak legs of aphids won't allow them to crawl back up.
Putting on some garden gloves and knocking them off of stems, leaves, flower buds, or wherever you see them is a great way to remove aphids. Drop them into a bucket of soapy water to kill them. Cutting or pruning off the affected areas and dropping them into the bucket is another effective method.
Here are some tips for manual aphid removal:
- Use a strong stream of water to knock aphids off your plants.
- Put on garden gloves to protect your hands.
- Knock aphids off of stems, leaves, flower buds, or wherever you see them.
- Drop them into a bucket of soapy water to kill them.
- Cut or prune off the affected areas and drop them into the bucket.
Remember, a strong blast of water is often the most effective way to remove aphids from your plants.
5. Trap Crop
Using a trap crop is a clever way to keep aphids away from your valuable plants. Planting a sacrificial crop around the perimeter of your garden can be an effective way to lure aphids away from your main crops.
Aphids tend to work their way from the outside in, so it's best to plant trap crops around the perimeter of your garden early in the season. This will give them time to spread and bloom before your main crops get going.
Some good trap crops for aphids include nasturtiums, calendula, and nettles. These plants are attractive to aphids and will lure them away from your main crops.
Once the aphids swarm the trap crops, pull them up and throw them in the trash. This will help prevent the aphids from spreading to your main crops.
Here are some good trap crops to consider:
- Nasturtiums
- Calendula
- Nettles
Remember to compost aphid-infested plants only if your compost pile gets to a high enough temperature to kill the aphids (around 140°F is optimal). Be sure to keep the compost far away from your garden area to prevent any remaining aphids from spreading.
Natural Pest Deterrents for Gardens
Aphids are one of the most common garden pests, and they can cause a lot of damage to your plants.
They feed on a wide range of plants using their piercing mouthparts to suck out all the juice, causing foliage to warp and curl.
A larger aphid infestation can also open the door to aphid-transmitted viruses, which can be incurable.
To control aphids naturally, you can take advantage of their weaknesses by using essential oils.
Create your own spray mixture with essential oils like peppermint, clove, rosemary, and thyme, using 4 to 5 drops of each mixed with water in a small spray bottle.
Spray on affected plants to target adult aphids, as well as aphid larvae and eggs.
Aphids also secrete a sticky substance called honeydew, which quickly becomes infested with black sooty mold.
Using natural pest deterrents can be more effective than chemical methods and is better for the environment.
Understanding Aphids
Aphids are tiny, soft-bodied insects that feed on plant sap, often occurring in colonies underneath leaves or on new growth. They can cause wilting and yellowing of plants, and their sugary waste, called honeydew, attracts ants and can lead to sooty mould growth.
Aphids have pear-shaped bodies, are usually around 1/16 to 1/8 inch in diameter, and can be various colors including brown, black, red, yellow, or green. They can also have a furry appearance and tube-like structures at the end of their abdomens.
If you suspect you have aphids, look for curling and stunted leaves, a sticky substance on the leaves called honeydew, and/or distorted flowers/fruit. You may also notice slowed growth or young plants dying altogether.
Here are some common signs of aphids:
- Curling and stunted leaves
- Sticky substance on leaves (honeydew)
- Distorted flowers/fruit
- Slowed growth
- Young plants dying altogether
Grow the Right
Growing the right plants can be a game-changer when it comes to managing aphids. By planting varieties that attract beneficial insects, you can create a balanced ecosystem that naturally keeps aphid populations under control.
Beneficial insects like ladybugs and lacewings are attracted to clover, mint, dill, fennel, and yarrow. These plants are like a welcome mat for beneficial bugs.
Planting natural aphid repellents like catnip, garlic, chives, onion, and allium can also deter aphids from your garden. I've seen this work like a charm in my own garden.
Some plants, like zinnias, dahlias, cosmos, asters, mustard, and nasturtium, are actually aphid trap plants. This means they lure aphids away from your prized plants, giving you a break from aphid management.

What Are They and Why Do They Love You?
Aphids, or plant lice, are tiny, soft-bodied insects that feed on plant sap. These usually green, yellow, brown or black lice occur in colonies, and you will often find them underneath leaves or on new growth.
They can lead to wilting and yellowing of plants, especially if the infestation is heavy.
Aphids will generally not harm healthy and well-established garden plants and trees.
Variety in Appearance
Aphids don't all look the same, which can make them tricky to spot. They come in a range of colors, including green, yellow, gray, red, brown, and black.
Some aphids have waxy, pear-shaped bodies that are only 1/16 to 1/4 inch long. Their bodies vary widely in color, depending on the species.
Green aphids, also known as greenflies, are often the most damaging because they blend in so well with leaves and stems. They can go unnoticed until their numbers grow out of control.
You might also spot yellow, gray, red, brown, and black aphids, and even the wild-haired, fluffy white woolly aphids that resemble mealybugs.

Signs of
Aphids are sneaky little pests, and it's essential to know what to look for to catch them early. Aphids have pear-shaped bodies, typically about 1/16 to 1/8 inch in diameter.
They can be a variety of colors, including brown, black, red, yellow, or green, which can make them hard to spot. But if you get up close, you'll notice tube-like structures at the end of their abdomens, called cornicles.
If you do have aphids, you'll likely notice curling and stunted leaves, which can be a giveaway. Aphids can also cause a sticky substance to form on leaves, known as honeydew.
