What To Know
- Dish detergent can be used on most plants, but it is always a good idea to test it on a small area first.
- Use a hose with a gentle spray setting to rinse the detergent off your plants thoroughly.
- While dish detergent can be effective in controlling aphid infestations, it is not a preventative measure.
Aphids, tiny sap-sucking insects, can wreak havoc on your plants, leaving them weakened and unsightly. While there are numerous chemical insecticides available, many gardeners prefer a more natural approach. Dish detergent has emerged as a surprisingly effective and eco-friendly solution for controlling aphid infestations.
How Dish Detergent Works on Aphids
Dish detergent contains surfactants, which are molecules that disrupt the waxy coating on aphids’ bodies. This coating protects them from dehydration and desiccation. When surfactants break down this coating, aphids become vulnerable to water loss and eventually die.
