Succulents are very hardy, but that doesn't make them immortal. Just like other plants, succulents are prone to pest infestations. Some of the most common succulent attacking pests are listed below:

1Mealy Bugs are unarmored, scaley insects found in moist, warm climates. They are the most common pest that feeds on succulents. They spread quickly from plant to plant and can be difficult to get rid of. 

How to get rid of them - 

The safest and most effective way to get rid of the mealy bugs is by using a 70% Isopropyl Alcohol. Empty the contents of the alcohol to a spray bottle, then spray the alcohol on your bug-infested succulent. You can also lightly sprinkle the alcohol directly onto your plant. The alcohol penetrates the sticky barrier that the mealy bugs have, killing them almost instantly. The alcohol evaporates quickly leaving only water on your succulent. 

2. Red spider mites are not spiders, they are actually mites that spin small, wispy webs to protect them from predators. Their webs are usually designed with an intentional pattern. They’re also particularly difficult to treat because, not only are they on the protected underside of leaves, but they are also protected by their web! Some chemical treatments won’t work unless applied directly, so you’ll probably have to deal with the webs first.

How to get rid of them - 

if your plants are infested by red spider mites, the best way to do it is to apply Neem Oil. With Neem Oil usage, reapply every 2-3 days until the infestation is gone. 

3. Scale Insects are many scale species are serious crop pests. Scale Insects are nasty pests because they spread quick, and are relatively difficult to remove. Scaled Insects' hard armored shell is very effective at keeping away predators.

How to get rid of them - 

If your succulent is infected with hard-bodied Scale Insects, the simplest way to treat them is to remove the branch or leaves that are affected. If this is distasteful to you, instead use a credit card or a knife (gently). You might damage the stem of the plant, but a little scar tissue will not harm the plant. You can also use Isopropyl Alcohol, Neem Oil and insecticidal soap. 

 4. Aphids feed on plant sap. They travel from plant to plant tasting different crops before settling into their chosen host. 

How to get rid of them - 

Just like mealy bugs, the safest way to get rid of Aphids is to spray isopropyl alcohol. 

5. Snails are the slimiest pests you will ever encounter in your garden. They’re so sneaky that you’ll almost never see one with your own eyes. They look harmless, however, they are anything but - chomping on your precious plants like it's their favorite past time.  

How to get rid of them - 

One of the most environmentally friendly and effective ways to keep snails and slugs from nibbling on your plants is by using egg shells. Crush eggshells into small pieces and scatter them around the base of the plant, the pot, or even on the plant itself - it acts as a deterrent. As slugs and snails have delicate skin, the sharp and piercing shards of the shell are unpleasant for them to navigate across and will help you to deter them.
