Rats can become unwelcome guests in Florida homes, searching for food and shelter in our warm climate.
Many homeowners are turning to natural solutions that work with nature instead of against it.
Certain plants have properties that rodents find unpleasant, making them excellent additions to your garden and yard.
Here are fourteen plants that Florida residents are successfully using to keep these pests at bay naturally.
1. Peppermint
The strong menthol scent of peppermint creates an invisible barrier that rats absolutely cannot stand.
This aromatic herb thrives beautifully in Florida’s climate, especially when planted in areas with partial shade and consistent moisture.
You can place peppermint plants near entry points like doorways, garage openings, and foundation cracks where rodents might try to sneak inside.

Growing peppermint is one of the easiest and most effective natural methods Florida homeowners use for rodent control.
2. Lavender
Lavender’s sweet fragrance delights humans but sends rats running in the opposite direction.
This Mediterranean beauty adapts surprisingly well to Florida’s warmer zones, particularly when planted in well-draining soil with plenty of sunshine.
The essential oils within lavender’s flowers and foliage create a scent profile that overwhelms rodents’ sensitive noses.
Florida gardeners often plant lavender near patios, walkways, and outdoor living spaces where they want to enjoy time without worrying about pests.
Spanish lavender and French lavender varieties tend to perform better in Florida’s humidity compared to English lavender.

With its pine-like aroma and woody stems, rosemary stands as a powerful natural deterrent against rats.

The flowers come in shades of yellow, orange, and red, creating stunning visual displays throughout the growing season.
French marigolds and African marigolds both work effectively, though French varieties stay more compact for smaller spaces.
Regular deadheading encourages continuous blooming and maintains the plants’ protective properties.
Marigolds also deter other pests like aphids and mosquitoes, making them multi-purpose garden heroes.
Many Florida residents plant fresh marigolds each season as an affordable and beautiful way to maintain natural rodent control around their properties year after year.
5. Daffodils
Daffodils contain alkaloids throughout their bulbs, stems, and flowers that make them toxic and repellent to rodents.
While daffodils typically prefer cooler climates, certain varieties can succeed in North and Central Florida with proper care.
Rats instinctively avoid areas where daffodils grow because their keen sense of smell detects the unpleasant compounds.
Planting daffodil bulbs in fall gives them time to establish roots before Florida’s mild winter.
