8 Ways to Get Rid of Cactus Bugs and Bring Your Succulent Back to Life

Most cacti grow in the southernmost states of the USA, like Arizona, California, and Texas. They are also highly adaptable as indoor plants.

These plants are specialized in retaining moisture for long periods, and their attractive patterns and colors make them desirable houseplants.

Cactus Bugs

Cacti and succulents have tough adaptations that protect them from predators and allow them to survive in harsh environmental conditions.

However, they are still susceptible to various pests and diseases.

Among these pests that can feast on your cacti are Chelinidea vittiger or cactus coreid.

These are brown or black bugs with yellow veined wings and yellow stripes on their heads.

These bugs are thick, roughly 10 mm long, and have a teardrop shape.

The cactus bugs are similar to the well-known squash bugs. But the latter lacks the distinctive yellow pronotum, which is a stark indication of a cactus coreid.

If your houseplant has become a victim of this bug infestation, you can employ a few steps to save your cacti.  

Physically detaching the bugs, employing insecticides and other chemicals, and watching out for other pests can help bring your cactus back to life.

Physical Treatments

Natural treatment is the easiest and most effective solution to eliminate these bugs from your plant.

1. Use a Garden Hose

You need a garden hose to help you direct the stream of water towards the bugs to get them off the cactus pads.

  • Remove the cactus bugs before they are firmly attached to the arm of your cactus.
  • A stream of water easily removes the crawling bugs.
  • Set your garden hose to a gentle water velocity and monitor the stream’s pressure.
  • Direct the water towards the bugs to blast them off the leaf surface.
  • Make sure that the stream of water isn’t directed with too much pressure, or else it might break off a part of your cactus.
  • Cactus have many hidden areas, making it easier for these bugs to hide.

Some cactus bugs that are too strongly attached to your plant will withstand the water pressure. For those, you will require manual removal.

  • Garden tweezers can help you remove individual bugs faster and easier.
  • The pests reside at the base of your cactus in huge amounts. This is the area where you must pay extra attention.
  • Pick the bugs and put them in a bag so that you can easily dispose of them far away from your cactus with no chance of recolonizing.
  • Alternatively, you can drop the bugs in a bucket of warm soapy water, killing them instantly.
  • Grab your garden tweezers and treat your plant early in the morning or at night to make the treatment easier for you.

  • Ensure that you are using a natural dish soap and not a formula with harsh chemicals that can damage your plant.
  • It is essential to spray a small part of the plant with this mixture first and monitor the area for a day.
  • If there is no damage to the cactus pads, you can continue spraying the rest of the plant.

4. Treatment With Rubbing Alcohol

Before applying concentrated insecticides, it is better to use a natural solution to get rid of cactus coreid bugs.

  • If the bugs have infested parts of the plant, you can treat them with a cotton swab and a mixture of alcohol and water.
  • Mix 1 cup of rubbing alcohol with 4 cups of water and fill this solution in a spray bottle.
  • Test by spraying a leaf with the solution and then leaving it for a few days for signs of burn from the alcohol.
  • If you do not see any damage, continue spraying the affected parts of your plant.
  • Similarly, you can spot-treat visible cactus bugs by dipping a cotton swab in concentrated rubbing alcohol and applying directly to the pests.

  • Treat the affected parts of your cactus as soon as you spot any pests and diseases.
  • Ensure correct fertilization, ventilation, and correct watering schedule for your cactus.

8. Check for Diseases in New Plants

  • If you see signs of bug infestation after a few days, you can get rid of the new plant or return it to the nursery.
  • Do not allow the new plant foliage to touch your cacti because it is easier for bugs like cactus coreid to crawl from the new plant and hide in your old cactus.

Mealy bugs are white insects, fuzzy in appearance, and can lay their eggs in the soil.

  • To get rid of mealybugs on the cactus, spot treats the visible mealybugs infestation with 70% rubbing alcohol.
  • If the infestation is spread over the plant, pour the alcohol solution into a spray bottle and mist the whole plant every week for 2 to 3 weeks.
