Flea beetles are pests that can wreak havoc on your plants. They are small, dark brown insects and they feed on the leaves of your vegetables, fruits, and flowers. If you have flea beetles in your garden, you need to know how to prevent them from eating up all of your crops.

Flea beetles can be an annoying and frustrating pest to gardeners, but there are some effective methods to combat swarming insects. Tachinid flies and braconid wasps are excellent predators for flea beetles and are also useful in combating tomato hornworms. However, these predatory insects can be hard to obtain commercially.

There are several ways to get rid of them if you have them in your garden now; however, it is important that you take steps now so that they do not become a problem later on this summer when they are more active and hungry. Here are some tips on how you can get rid of these pests before they ruin all of your hard work.

Neem oil

Neem oil is a natural insecticide and can be used on plants to control flea beetles. This oil can be applied to the top and bottom leaves of the plant. It is important to test a small area first before spraying the whole plant. This oil is highly toxic to larvae. It also affects the plant’s fragrance, which will make it less attractive to flea beetles.

This insecticide is also effective against fall armyworm, a major pest of food crops in the western hemisphere. However, to prevent insect damage, the treatment must be applied before the insects arrive in the field. This will cause the insects to march past the field rather than take up residence. Additionally, neem extracts can control the Colorado potato beetle, a significant pest in North America and Europe. This pest is largely resistant to broad-spectrum insecticides, so using neem is an effective way to control it.

Another beneficial effect of neem is its antifeedant and growth-regulatory properties. Neem also inhibits the development of eggs in insect pests, making it an effective way to protect plants. In addition, the oil has no residual effects, and it breaks down rapidly when exposed to sunlight or rain.

Diatomaceous earth

Diatomaceous earth is a natural deterrent that works to prevent flea beetles from infesting plants. It works by damaging the exoskeleton of these insects. Depending on the size of the insect, the diatomaceous earth can kill it in 24 hours. It is not effective on plants that are actively growing, however.

You can also use a natural repellent that kills flea beetles by spraying the area with nematodes, which attack the flea beetles before they hatch. Adding a coating of diatomaceous earth to your plants can also help. This organic powder can be applied to the top and bottom of your plants. You can also sprinkle it on the soil if you have a heavy infestation.

Flea beetles usually live in dead garden foliage and trash, so it’s important to remove these sources of food. Another natural solution is to use diatomaceous earth, which is a natural deterrent and harmless to humans and pets. It works by scoring the outer shell of the insect, causing it to die. However, diatomaceous earth is not as effective when wet, so you may need to reapply it to get the desired effect. Another way to deter flea beetles is to use neem oil or horticultural oils.

Diatomaceous earth is available in several grades, with food grade being the safest for humans. Food-grade diatomaceous earth is safe to touch and does not contain crystalline silica, which is hazardous to the respiratory system. Diatomaceous earth is also available in swimming pool grade, which is used for filtering pools.


Catnip can be grown easily and is easy to care for. It is very hardy and can be grown in a wide variety of soils. You can buy catnip seeds from many seed companies. Seeds are small and can be directly sown in the garden or started in flats. Once the seedlings have five leaves, you can transplant them. During their early development, you should keep them safe from cats. You can also divide plants by cutting their root mass in half.

Basil and catnip are great repellents for flea beetles and other insects. These plants also smell great and can be used in cooking. Catnip extract is also an effective insect repellent. It is a great ornamental plant that loves the full sun.

Flea beetles are tiny, shiny black bugs that can cause damage to your plants. The beetles are about the size of a flea but are so small that they can’t be easily seen. Some types have white stripes and others have stripes. These critters can cause serious damage to your plants.


Sage is a natural insect repellent and can be used in the garden to protect plants from fleas. The foliage of this herb is grayish-green and contains a distinctive odor. It is also used in herbal teas and incense. In addition to repelling fleas, sage can also attract beneficial insects such as spider mites. Sage is a perennial that grows best in hardiness zones 5 to 8 but can be grown as an annual in warmer regions. It produces a strong smell that is disliked by many animals, including fleas. Adding sage to your herb garden will make your flowers smell fragrant, keeping mosquitoes and flea beetles away. Sage has downy gray-green leaves and purple to blue flowers. It is also used for medicinal purposes and for culinary purposes.

Sage is also useful for repelling cabbage moths and carrot flies. It is a perennial herb that is difficult to intercrop with other plants. However, it is possible to find varieties that work well with a variety of plants. Common sage is a strong deterrent but winter sage is less effective. In addition to sage, savory and thyme are great for repelling insects. Thyme and savory plants are easy to grow and inter-crop.


Hyssop, a natural remedy, can keep flea beetles from feeding on your plants. It can also be used as a trap crop in the garden. It grows rapidly and can be planted between eggplants. It is a good idea to sprout the seeds before planting eggplants in your garden. To spot flea beetles, check the leaves of radishes and eggplants. You will notice that they have holes in their leaves.

If you can’t find any beetles on your plants, you can try covering them with row covers. This will keep them from accessing your young plants. If you can’t avoid the problem, you can also spray the soil with diatomaceous earth. In addition, if you see a heavy infestation, you can also try spraying pyrethrum on the underside of the leaves of your plants. Similarly, you can try applying hot pepper spray to your plants to repel the flea beetles.

Flea beetles are the biggest threat early in the planting season. They emerge from underground when outdoor temperatures reach 50oF and feed on seedlings and young plants. Their eggs are laid at the base of stems, while the larvae feed on the roots. They can easily destroy leaf greens, and they usually attack new leaf growth first.


Flea beetles can be very destructive to your Nasturtium plants, so you should take steps to prevent this problem. Using a trap crop, such as radish, can be very effective in keeping this pest under control. By planting these plants early in the season, you will allow the seedlings to grow quickly and the predatory insects will feed on them, thus preventing flea beetles from infesting your plants.

Nasturtiums can also be infected with aphids, which are common garden pests. Aphids prefer wet, cool weather and plants with thick foliage. You can identify aphids by looking for their yellow or black eggs. You can easily remove these eggs by scratching them off with a fingernail or washing them with dish detergent. Aphids are not dangerous to humans, but you should avoid letting your Nasturtiums remain infested.

Flea beetles usually eat the foliage of the plant. They leave shot holes in the leaves, which may indicate the presence of nymphs. Flea beetles are most dangerous to seedlings and young plants. They can cause extensive damage to young plants and can cause the plants to die. Adult flea beetles lay their eggs at the base of stems, and the larvae feed on the roots of the plant. Usually, they attack the new leaves, which are also the most vulnerable.


Flea beetles are small critters that cause small holes in the leaves of plants. They are a type of leaf beetle and are found throughout North America. They are small and have powerful hind legs that cause them to jump. When disturbed, the flea beetle will move on to a new host plant. These insects feed on the roots and tubers of young plants, and some species can cause viral diseases in plants.

One tried and true method for preventing flea beetles on plants is to use neem oil. This substance contains a naturally occurring chemical called Azadirachtin that repels flea beetles. Combine neem oil with half a teaspoon of Castile soap. Mix the mixture and spray the plant. Before applying the mixture to plants, it is best to test it on a small leaf and observe its reaction to the spray. If you notice any damage, then lessen the amount of neem oil.

Another natural way to prevent flea beetles is to sprinkle wheat bran meal around the plants. This is an effective natural way to kill flea beetle larvae without harmful side effects. Applying the mixture around the plants will ensure that the flea beetles do not breed in that area.
