Squirrels and mosquitoes are considered major garden pests, since squirrels eat flowers and seeds, and mosquitoes swarm above gardener’s heads, administering painful bites to the skin. To prevent insect bites and damage to prized plants, certain flowering bulbs and herbs are planted in the garden to naturally deter mosquitoes and squirrels.

Narcissus flowers are in the same family as daffodils and jonquils. They thrive in areas with full sun and require minimal maintenance. The flowers have a flavor that squirrels detest because of the plants’ poisonous bulbs. After eating the plants, squirrels exhibit signs of vomiting, diarrhea and skin rash.

Crown Imperial
Crown imperials are perennial flowering bulbs with glossy green leaves and red, orange and yellow blooms. The plant grows 2 to 3 feet tall and thrives in areas with well-drained soil and full sun. The fragrant foliage of the crown imperials emits a musky odor that repels squirrels, deterring them from entering the garden.

Lemon Balm
Lemon balm is a sweet herb that belongs to the mint family. The green and golden leaves of the lemon balm contain citronella oil, which repels mosquitoes and deters them from swarming the garden. The plant also prevents mosquito bites when a handful of lemon balm is crushed and rubbed on the skin.

Catnip is a perennial herb found in various cat toys and foods. The oil from the plant’s leaves contains the compound nepetalactone, which repels mosquitoes. According to ScienceDaily.com, nepetalactone is 10 times more effective than DEET. Catnip requires minimal maintenance and is grown in containers near patios and decks to deter mosquitoes.[1]

Lavender is an aromatic herb that is grown in outside containers and garden beds. The plant is comprised of greenish-gray foliage and lavender-blue flowers. Lavender plants repel mosquitoes because of a compound found in the flower known as linalool, which is toxic to the flying insects. Linalool is also used as an ingredient in cosmetics and perfumes for its flower-like odor.

Scented Geranium
A variety of scented geranium known as lemon rose is effective at repelling mosquitoes, since the rose-scented leaves contain citronella oil. The annual herbal plant grows 6 inches to 4 feet tall with pale pink and white flowers that bloom in the summer. Scented geraniums are planted in clay pots and plastic containers near patios to deter mosquitoes and to freshen the air with the plant’s sweet scent.
