Mosquito Prevention
Minimize bite exposure and suppress vector habitats around your home using active, evidence-based physical barriers and chemical protectants.
Personal Protection
EPA-Registered Repellents: Always use repellents certified by the EPA. The most effective active ingredients are:
- DEET: The gold standard. Provides hours of protection. Safe for children over 2 months.
- Picaridin: Comparable efficacy to DEET without the oily residue or odor; safe on gear/synthetics.
- Oil of Lemon Eucalyptus (OLE): Natural plant-derived option providing long-lasting deterrence (do not use under 3 years).
Protective Dress: Wear loose-fitting, long-sleeved shirts and thick-weave pants. Mosquitoes can bite through tight-fitting athletic fabrics like yoga pants.
Permethrin Treatment: Pre-treat clothing, hiking boots, and camping gear with 0.5% permethrin spray. It bonds to fabric fibers and repels or kills insects on contact.
Residential Safeguards
Eradicate Standing Water: Mosquitoes lay eggs in containers as small as a bottle cap. Weekly, empty and scrub:
- Flower pot saucers and plant drip trays.
- Pet water bowls, bird baths, and dog kennels.
- Tires, tarps, toy buckets, and garbage can lids.
Maintain Physical Barriers: Fit all windows and doors with tight-fitting screens (18x16 mesh or smaller) and seal gaps with weatherstripping. Repair tears immediately.
Treat Non-Drainable Water: If water cannot be drained (such as in ponds or rain barrels), apply biological larvicides containing Bti (Bacillus thuringiensis israelensis). These tablets target mosquito larvae without harming birds, fish, or pets.
Do Any Plants Repel Mosquitoes?
While many sources claim that growing specific plants like citronella, lavender, rosemary, or marigolds in your yard will keep pests away,there is no strong scientific evidence showing that living plants reliably prevent mosquito bites. Simply having these plants in your garden does not release a high enough concentration of volatile oils into the air to establish a protective barrier.
A clear distinction must be made between living garden plants and their extracted active compounds. Essential oils extracted from plants (such as citronella, lemongrass, or eucalyptus) do possess insect-repelling properties when refined and applied to the skin or evaporated in high concentrations. However, raw essential oils evaporate rapidly, providing protection for only 20–30 minutes, and can cause skin irritation if applied undiluted.
For reliable, long-lasting defense, always use EPA-registered formulated repellents containing active ingredients like DEET or Picaridin, or botanical derivatives likeOil of Lemon Eucalyptus (OLE), which are scientifically tested and clinically proven to protect against vector species.
