Get Rid of Cactus Bugs – 5 Ways to Prevent and Treat an Infestation
Cactus bug damage often appears as sunken spots with brown edges and corky centers. To prevent an infestation, keep your plants healthy by providing them with plenty of light, humidity, and room temperature between 65 °F and 75 °F. To treat an infestation, follow these five tips for preventing cactus bug attacks and more effective bug control.
1. Change Your Cactus’ Environment
If you notice cactus bug eggs on your cacti, remove the eggs to prevent the bugs from hatching. If you notice adult cactus bugs on your cacti, try changing your cactus’ environment to make it less appealing to pests. Place your cactus plants in a more humid environment.
Since cactus bugs thrive in dry environments, adding more humidity to your cacti’s environment makes it less appealing to the cactus bugs. You can increase humidity around your cacti by placing them near a water source, like near a water feature or next to a humidifier.
You can also mist your cacti with water once a week. Avoid watering your cacti during the hot afternoon hours, as this may increase the risk of root rot.
2. Re-Pot Your Cactus
Cactus bugs feed on the cactus’ roots. By repotting your cactus, you can effectively treat an infestation by removing the pests’ source of food. You can treat an attack on your cactus by repotting it during the early spring or late fall when outside temperatures are mild.
When repotting your cactus, you’ll want to remove the cactus bug eggs and cactus bugs from the roots. However, do not damage the cactus roots while removing the pests.
You can also try placing your cactus in a greenhouse or indoors if you live in a cooler climate and the cactus bugs are prevalent outdoors.
3. Use Neem Oil
Neem oil is a natural insecticide that effectively kills cactus bugs. Apply neem oil to your cacti once a week for two weeks to effectively treat your cacti. Avoid applying neem oil when temperatures are above 85 °F to prevent the oil from burning your cacti.
While neem oil effectively kills cactus bugs, it may also cause damage to beneficial insects like bees. If you have many cacti growing in your garden, it may be best to treat each cactus with neem oil.
However, if you have only a few cacti, you can also apply neem oil to your garden soil to prevent cactus bugs from attacking your cacti.
4. Treat with Diatomaceous Earth
Diatomaceous earth is a natural pesticide that kills cactus bugs by dehydrating pests. You can apply diatomaceous earth to the cactus soil or the cactus’ leaves to effectively treat an infestation.
Avoid applying diatomaceous earth to the cactus flowers, as it may damage the plant. Diatomaceous earth is effective at killing cactus bugs because the pests ingest the powder, and it cuts their insides.
You can apply diatomaceous earth to your garden soil to prevent cactus bugs from attacking your cacti. Diatomaceous earth is safe for people and pets, but it is harmful to insects.
5. Try Pesticides
If cactus bugs have severely damaged your cacti, you can try using a chemical pesticide. When using a chemical pesticide, always follow the product’s instructions precisely to avoid harming your cacti or yourself.
You can use a chemical pesticide like carbaryl, endosulfan, or malathion to effectively kill cactus bugs and prevent future attacks. You can also use neem oil, which is a natural insecticide that effectively kills cactus bugs, which we discussed above.
Be sure to carefully read all product labels and select the product that is right for your cacti.
