Indoor plants are just as susceptible to insects and pests as outdoor plants. The best way to combat diseases and pests is to make sure that plants are healthy. Plants that are watered and fertilized properly and have dead foliage removed regularly are less likely to be attacked by insects. Place plants in cooler temperatures, since pests are more likely to invade in warmer temperatures. Check regularly for insect damage, and take immediate steps to control problems. A number of homemade insecticides can help with indoor plants.
Soap Spray
Add one tlbsp dishwashing soap to one gallon water. Mix well and use as spray to get rid of mealy bugs, aphids, scales, and thrips. Test a few leaves first before spraying whole plant. (Reference 2)
Ammonia
Mix together one part household ammonia to seven parts water to make a spray. Use to get rid of aphids, mealy bugs and thrips.
Baking Soda
Indoor plants are often afflicted with fungus such as blackspot and powdery mildew. Make an effective fungus spray by mixing 1 tsp. baking soda, 1 qt. warm water and 1 tsp. dishwashing soap. Spray on affected plants.
Garlic
Mix together 85 g minced garlic with 2 tbsp. mineral oil and leave for 24 hours. Strain mixture and remove garlic. Add remaining liquid to 1 pt. water with 1 tsp. liquid dish soap and mix well. To make spray, mix 1 to 2 tbsp. of mixture with 1 pt. water. This spray is very effective for getting rid of a number of insects, including aphids and white flies. The antifungal properties of garlic control fungal diseases like mildew and leaf spot.
