Tiny silver bugs crawling around in your houseplant soil are usually springtails. There are other common tiny silver bugs including Thrips, Pill Bugs, Springtails and Mealybugs. If left unchecked they can damage your house plants, they are also unsightly and annoying. To get rid of these tiny silver bugs you can reach for natural remedies like diatomaceous earth and Neem oil or chemical insecticides.
This article will also cover ways to stop silver bugs from damaging your houseplants.
4 Tiny Silver Bugs and How to Control Them
Here are 4 common tiny silver bugs that can infect your houseplants. Find out how to identify them and control them before they damage your plants.
1. Springtails
Silver bugs or springtails are usually silver or gray but can also look like tiny white bugs. They are challenging to see with the naked eye due to their tiny size and quick movements. However, under certain conditions and with good lighting, it is possible to spot them, especially when they jump. They thrive in moist soil conditions and are harmless to humans and pets but can cause damage to your plants if not controlled.
They are typically less than 1/16 inch in length and have a distinctive tail-like appendage that helps them jump which you cans see with a magnifying glass. You may also notice them in large numbers on the surface of the soil or crawling around the plant roots. To determine if you have springtails, you can try tapping the soil surface with a piece of white paper. If the bugs jump onto the paper, they are likely springtails.
They thrive in moist soil conditions and can multiply quickly if left unchecked. Other bugs that may be mistaken for springtails include fungus gnats and spider mites. Understanding the differences between these pests can help you choose the best method for eliminating them from your plants.
How to Control Springtails
Check out the following methods to control springtails on your houseplants.
Diatomaceous Earth
Diatomaceous earth is a natural substance that is made from the fossilized remains of diatoms, which are tiny aquatic organisms. It is a fine powder that is safe for humans, but deadly for insects. When insects come into contact with diatomaceous earth, it dries out their exoskeletons, causing them to die.
To use diatomaceous earth to get rid of springtails sprinkle a thin layer on the surface of the soil. Use a small brush to gently work the powder into the top layer of soil and repeat this process every few days until the silver bugs are gone.
Neem Oil
Neem oil is a natural insecticide that comes from the seeds of the Neem tree. The good news is that it is safe for humans and pets, but deadly for insects. When insects come into contact with neem oil, it disrupts their hormonal balance, causing them to stop feeding, mating, and laying eggs.
To use Neem oil the first step is to dilute it with water in a spray bottle. Follow the instructions on the pack. Shake the bottle well to mix the solution then spray it on the surface of the soil and the leaves of the plant. Repeat this process again in a week until the silver bugs are gone.
Insecticidal Soaps
Insecticidal soaps are a safe and effective way to control silver bugs. They work by penetrating the insect’s outer shell, causing dehydration and ultimately death. Insecticidal soaps are made from natural ingredients and are safe for use on most houseplants. You can also use an organic detergent to make up your own soap spray. Add 1-2 drops of organic dish detergent to a spray bottle and coat the insects with the soapy water.
To use insecticidal soap, mix the recommended amount with water and spray directly onto the affected plants and soil. Be sure to follow the label instructions carefully, as overuse can damage plants.
Insecticides
Insecticides are another effective way to control silver bugs. These insecticides are absorbed by the plant and when the silver bugs feed on the plant, they ingest the insecticide and die.
Insecticides are available in both liquid and granular forms. To use, simply apply the recommended amount to the soil around the affected plants. Be sure to follow the label instructions carefully, as overuse can damage plants.
2. Thrips
Thrips are a common houseplant pest. They are tiny, slender insects that belong to the order Thysanoptera. They are typically less than 1/16 inch (1-2 mm) in length and have fringed wings. They have piercing-sucking mouthparts that they use to puncture plant cells and feed on the plant’s sap.
This can cause stippling or silvering of leaves and affect plant growth. Thrips can also transmit plant viruses. Thrips can enter homes through open windows, open doors, in leaf litter or mulch or on infested plants brought inside. These tiny insects they can easily spread from plant to plant.
How to Control Thrips in Houseplants:
Neem oil is a natural and organic insecticide that can effectively control thrips on houseplants. It works by disrupting thrips’ feeding and reproductive processes.
Simply mix neem oil with water following the instructions on the product label. Spray the solution evenly on the foliage and stems of your houseplants, ensuring good coverage.
Repeat the application every 7-10 days or as recommended on the label to target newly hatched thrips and break their life cycle before they cause serious damage.
Neem oil is available from good garden centers.
3. Pill Bugs
Pill Bugs, (also known as sowbugs or woodlice) are terrestrial crustaceans. They live in damp, decaying organic matter and are usually less than 1 inch (2.5 cm) in length. Pill bugs are mostly scavengers that feed on decomposing organic matter, such as dead leaves, mulch, and decaying wood. While they are not plant pests themselves, they may indirectly affect houseplants by eating the mulch or other materials in pots.
Pill bugs are attracted to moisture and can thrive in overly damp potting soil. If soil conditions are consistently too wet, they may gather in plant pots, potentially disrupting the root zone.
They seek shelter in dark, moist environments during the day and may hide under pots, in saucers, or among plant debris and are more active at night.
How to control pill bugs in houseplants
The best ways to control pill bugs in houseplants is to let the top soil of your houseplant dry out between watering, avoid overwatering and make sure your pots have adequate drainage.
You can also remove excess mulch from the top of the pot and remove the bugs at the same time. Simply take the affected plant outside and pour the mulch off the surface out into your compost heap. You can take the time to manually remove the bugs with a small spade or gloved hand.
Pill bugs are generally harmless to houseplants and play a role in decomposing organic matter, contributing to nutrient cycling in the soil. In most cases, they are not considered pests of indoor plants. However, if their population becomes excessively large it is best to remove them.
4. Mealybugs
Mealy bugs are small, soft-bodied insects that are common houseplant pests. They are typically found on the stems, leaves, and in the leaf axils of plants. They have oval-shaped bodies, are usually colored gray or white and can be covered in a white, waxy substance. This wax gives them a cottony or mealy appearance and serves as protection.
Mealybugs feed by piercing the plant tissue with their needle-like mouthparts and sucking out the plant’s sap. This feeding can weaken the plant, causing stunted growth, yellowing leaves, and leaf drop. In addition to the physical damage, mealybugs excrete a sticky, sugary substance called honeydew, which can attract ants and promote the growth of sooty mold on plant surfaces.
How to control mealybugs
As soon as you notice mealybugs on one of your houseplants, isolate the infested plant to prevent the spread of the pests. Use a soft brush or a cotton swab dipped in rubbing alcohol to gently remove the mealybugs from the affected areas. Focus on areas where the insects are concentrated, such as leaf axils and the undersides of leaves.
If the infestation is severe, prune off the heavily infested branches or stems and dispose of them in a sealed plastic bag. Apply insecticidal soap or Neem oil to the affected areas of the plant. They help control mealybugs by suffocating them or disrupting their outer waxy layer. Mealybugs are persistent pests, and you may need to repeat treatments every 7-10 days to target newly hatched mealybugs and any survivors.
