Use effective deterrents to keep chipmunks and other pests away from your tomato plants. Adding a water feature to the property is one way to keep pests out of the garden. Make a spray with cayenne pepper, garlic and water to chipmunks and other pests. The spray takes about two days to make and should be used weekly and after rains to dissuade pests effectively.
- Mix cayenne pepper and garlic
Mix 1 quart of water, 2 tablespoons of cayenne pepper and 2 finely minced cloves of garlic in a lidded container. Leave the container closed for two days, then strain the mixture into a spray bottle or a garden sprayer.
- Spray plants in the garden
Coat the stems, leaves and fruit of the plant with the mixture at least once per week. Reapply the mixture after heavy watering or rainstorms to maintain its effectiveness.
- Install a water feature
Chipmunks may enter gardens in search of water during the hottest months of the year. Add a water feature, such as a birdbath, in an area away from the tomato beds as an alternative for chipmunks and other pests. Keep fresh, clean water in the birdbath during summer to prevent damage to tomatoes.
