Controlling mosquitos naturally Photos and text courtesy of EarthEasy.com.
The first line of defense against mosquitos is to seal their point of entry. Mosquitos are most active in the early morning and early evening. They seek areas of still air because they are hampered by breezes. Close windows and door on the side of your house which is opposite the breeze. Then try:
Remove standing water sources. Change your pet's water bowl regularly.
Buy a small jar of citronella oil at your local hardware store and a roll of small sticky-backed felt circles from any craft or picture framing shop. (The felt circles are used on the back of frames as wall protectors.) Using an eyedropper, put a few drops of citronella on the felt and stick it near areas where mosquitos congregate - usually wind-sheltered areas. Only use a few drops - too much oil will cause the glue-backed felt to unstick and fall. Add a few drops of oil once a week during mosquito season.
If you're using the barbeque, throw a bit of sage or rosemary on the coals to repel mosquitos.
Make your own natural bug repellent using crushed fresh parsley in a jar of apple cider vinegar. Rub into skin on exposed areas or dip a kerchief in and wear around your neck or as a hatband.
Another effective natural bug repellent can be made using garlic juice. Mix one part garlic juice with 5 parts water in a small spray bottle. Shake well before using. Spray lightly on exposed body parts for an effective repellent lasting up to 5 - 6 hours. Strips of cotton cloth can also be dipped in this mixture and hung in areas, such as patios, as a localized deterrent.
