Finding pests on your houseplants can be very worrying. In most cases all house pests are unwanted (except maybe if you live in Australia). We want to do our best to keep our houseplants healthy. Learning about the possible pests that could infect your houseplants, will help you look after them in the long run. Pests are a pain especially when they start causing problems to the health of your plant.
If you notice any pests on your houseplants you must isolate the plant to ensure the pests don’t spread to the neighbouring plants.
It’s good to get into a habit of checking your houseplants weekly for pests. This could be on watering day or when you clean the leaves for dust.
It is hard to know where pests come from. Sometimes they are already in the soil when you bring a new plant home. Others can be brought in with the fruit and vegetables from our food shop. All plants will react differently depending on their environment. Regular pest checks are so important. The sooner you find them the better chance your plant has of surviving.
Mealybugs are insects that are small, white and fluffy resembling cotton wool on your houseplants.

Treatment: The best remedy for getting rid of mealybugs will depend on how badly they have affected your plant. The first thing you will want to do is isolate this plant from your other plants.
If you find just one or two,you can wipe them off with a cotton bud or small towel. If the bugs have taken over your entire plant, the best thing to do is place your houseplant in the shower. Thoroughly clean your houseplant’s leaves with water.
It can be hard to get rid of all the sticky dew. Rubbing alcohol can help with this. After the pests have been cleared, you will want to spray your plants with a diluted neem oil. In most cases the packaging will give a proper description on how to dilute it.
Keep a close eye on your plant for the next couple of weeks. It’s important to make sure the soil is free of mealybug eggs. You can go ahead and re-pot your plant for peace of mind. Keep washing and spraying your plant with neem oil regularly until the bugs appear to have vanished.
Spider mites are very small and hard to see. They look like little yellow/white dots moving around your houseplants. Ivy is a plant that is prone to having spider mites.

When the leaf is damaged, it will eventually yellow, wilt and fall off. If your plant is losing leaves and you are unsure of the reason, you may wish to search the foliage for cobwebs.
Treatment: Firstly you must isolate your houseplants to prevent other plants from infection. The good news is spider mites are very easy to treat. Firstly use a cloth or towel to thoroughly get rid of cobwebs and all visible spider mites. If possible, clean every single leaf. The spider mites will form webs on the underleaf. After all visible signs of webs and spiders have vanished, spray with a diluted washing up liquid.
