Natural Pest Control for Bougainvillea: Alcohol and Soap Sprays

Home Remedy Spray

Mix 1 tablespoon liquid dish soap per quart of water, OR use 1 part rubbing alcohol to 5 parts water with a squirt of soap. Spray thoroughly—tops and bottoms of all leaves—daily for 7 days, then every other day for 10 more days. This targets hatching eggs and mobile pests.

Why It Works

Alcohol and soap disrupt insect cell membranes and dissolve protective coatings. They're low-toxicity and safe for plants when not applied in direct sun or high heat.
