A guide to non-toxic pest control 6

You know how it goes: you’re in your kitchen, happily chopping veggies for that night’s meal, when an ant comes wandering by to check out the menu. Or you turn on the light in the bathroom and spot a silverfish scuttling away. Or you finally lie down for a well deserved rest, only to be plagued by the incessant whine of a bloodthirsty mosquito.

mosquito biteThis sucks.dr_relling via flickrThere’s a reason they’re called pests, and modern science has come up with plenty of sprays, baits, and potions to kill them or keep them at bay. But those remedies aren’t just bad for the bugs, they’re bad for you, too. Conventional pesticides contain toxic ingredients that can, according to the EPA, affect the nervous system, cause skin and eye irritation, affect hormones and the endocrine system, and cause cancer. As the New York State Department of Health delicately puts it, “The improper storage, application, or disposal of pesticides present potential health risks to the entire family, especially children.”

Yuck. So are there alternatives?

The short answer is yes. The longer answer is, it might take some experimenting on your part to find out what really works. Here are a few “natural” suggestions people seem to swear by; leave your own solutions in the comments section below.

ANTS

Get out: Things ants do not dig include citrus, mint, cinnamon, cucumber, dried chili pepper, and paprika. Try spraying or sprinkling these in anty areas. Other effective combat-ants include diluted liquid soap or boric acid (but keep the latter out of the reach of children and pets).

And stay out: Keep ants away by storing food in tightly closed containers, vacuuming crumbs, and putting pet food away for the night. Try spraying their usual pathways with a citrus-derived cleanser or vinegar. Some swear by the use of dry grits—ants apparently explode after eating them. Whatever sits easiest with your conscience.

BEDBUGS/ DUST MITES

Get out: Heat is the best weapon against these pesky critters; wash infested items in hot water or seal in plastic and place in the sun.

And stay out: Vacuum and wash bedding regularly, and clean up clutter. When buying used furniture, examine it thoroughly—and when it comes to mattresses, you can cast your “secondhand only!” rules aside.

EARWIGS

Get out: Two “natural” traps include a clean cat-food or tuna can filled with water and vegetable oil (if you can stomach a can full of drowned earwigs) or a damp, rolled-up newspaper (they’ll crawl inside to escape the heat). Or sprinkle boric acid or diatomaceous earth along known thoroughfares.

And stay out: Seal cracks in windows, doors, and screens, and remove wood piles or leaf piles by your house (earwig he love the damp and dark). Put up birdfeeders to entice more feathered friends to visit—they’ll spot the earwigs and chow down.

FLEAS

Get out: There are a few herbal remedies said to work for dogs (though they may not be safe for cats): spray diluted eucalyptus, rose geranium, or tea tree oil on your dog’s fur. Rub diatomaceous earth powder on your pet, or use an herbal shampoo. Or comb your pet’s fur with a comb dipped in soapy water, then freeze the water to kill the fleas—just warn your ice cream-hunting roommates first.

And stay out: Vacuum carpets and furniture frequently. And if you’re really up for an adventure, spray your yard with freeze-dried nematodes; the tiny worms eat flea larvae. Yum!

FLIES

Get out: Deterrents include citronella, pine oil, eucalyptus, cloves, basil, and bay leaves. And you can make your own flypaper by spreading a mixture of boiling water, corn syrup, and sugar on strips of brown paper bags! If you’re feeling really sadistic, suck flies up with your (solar-powered) hairdryer and listen to ‘em fry.

And stay out: Cover trash with a tight-fitting lid, and remove it regularly. Keep an especially close eye on compost and your fruit bowl—your bruised pear is a fertile fly’s dream.

LADYBUGS

Get out: They’re harmless, and they eat other pests—so don’t be too quick to get rid of them. But if you’re tired of a windowsill full of ladybugs, you can ward them off with essential oils (eucalyptus, lavender, cedarwood, etc.), lemon, or ammonia.

And stay out: Make sure screens are intact and properly sealed. The magical diatomaceous earth can come in handy here—sprinkled around the perimeter of your house—and planting cilantro, fennel, dill, and geraniums can help keep the ladybugs happy in the garden instead of seeking sustenance in your home.

MOSQUITOES

Get out: Ye olde essential oils come in handy once again; apply them straight, or look for natural insect repellents that contain them. Citronella candles or torches are a tried-and-true method for outside gatherings. And inside, sometimes just turning on a fan can do the trick.

And stay out: Make sure screens are intact and sealed. Remove standing water from gutters, pet dishes, toys, wheelbarrows, plant saucers, etc. Spray garlic oil on the shrubs and plants around your yard; this step is said to repel mosquitoes for up to four weeks. Of course, it might also repel your friends.

SILVERFISH

Get out: Plant-based repellents include cucumber (try placing strips or peelings in cabinets, closets, and basements, replacing them when they dry out), camphor, rosemary, cloves, and costmary. If you’re feeing trappy, set out a glass container with tape on the outside—the tape gives them enough traction to climb in, but leaves them with no way out.

And stay out: Like earwigs, silverfish thrive in dark, damp environments. They also think wallpaper paste is a mighty yummy treat. So repair or replace old wallpaper, seal cracks in walls and floors where possible, and consider a dehumidifier.

SPIDERS

Get out: They might creep you out, but most spiders are harmless—and are actually a good bet for keeping other insect populations down. Still, if you’d prefer to keep your house web-free, spraying a citrus essential oil in spider-prone areas can help keep them out. Placing chestnuts on windowsills and around exterior walls could also do the trick.

And stay out: Clean up clutter—especially wood and cardboard, which spiders find quite alluring. Dust regularly. But mostly, get over your arachnophobia! Ultimately, spiders might be the best form of non-toxic pest prevention you can find.

    Ants- mix up about 2 cups of cat food with 1/3 cup of boric acid powder. Place in empty, dry, beer or soda bottles and place on their sides against the foundation on the exterior of the house. Renew on solstices and equinoxes. (it gets moldy after a while) A friend swears by tansy planted under the kitchen window as ant bane.

    Cockroaches-If you see more than a single cockroach there is a water leak, pipe with condensation or some other source of water available to that roach within about 20 feet. Eliminate all possible water sources and moist mulch beds adjacent to the house/foundation, sweep the roof and check the gutters for good operation. Ruthless elimination of water sources will eliminate roaches even if food is available. Elimination of food sources may involve partial dismantling of the stove to clean all grease deposits. Keep all pet food in airtight metal containers. Cockroaches also can be suppressed with boric acid feeding stations. Freezing your house (drain the pipes first) in the winter will also kill roaches.

    Fleas- A handful of dried pennyroyal tossed into the dog bed cover (like a pillowcase) eliminated a long-term, persistent flea problem for me. The dog smelled better too. A quick Google reveals there may be a caution for pennyroyal use with cats. Do not apply directly to the cat.

    Flies- Place fly traps out when you see your first fly in the spring and renew/maintain several times over the warm season. Empty kitchen compost to an active pile daily. Add crushed charcoal to compost and animal manure piles to speed composting and deny fly larvae habitat.

    Relatives- Put a bit of red Thai curry paste in all food items. Keep adding more at each meal until they go away.

    Be cautious of using the garlic-oil trick to keep away pests. Spraying any type of oil on foliage in the summer can cause serious damage. It's kind of like rubbing baby oil on your skin and then laying out in the sun between the hours of 10 and 3. Maybe a water-based garlic spray would be better. Your Friendly Neighborhood Arborist

    Recently I just about ripped my hair out from a persistent ant infestation (I'm all respect when they're not in my kitchen or my laundry). My housemate and I had a lot of success with Dr. Bronner's peppermint (ants hate it) biodegradable soap spread around the exteriors of our windows and doors. You can also spray the ants directly with a dilution of the soap and water to kill them on contact.Next we found their trail toward our house and put a line of Dr. Bronner's around it to isolate them. We then placed dollops of a mixture of water, sugar, honey, and Borax inside that with them. This wards them off and reduces their numbers for several weeks, but you have to be vigilant and re-apply if it rains or starts to break down. And don't let your pets or kids eat it obviously! (It's not Raid, but it's also not for non-ant consumption.) Good luck!

    Fleas - Place flat pans (like baking pans) on the floor around the house, and fill pans with vinegar.  The smell can take some gettin' used to, but usually within a few days, all the fleas have sucessfully drowned themselves.Ants - Grits.  Spread generously over a mound.  Ants will gorge themselves until they die.  Ants will eat grits and will not stop eatin' grits until their stomachs literally explode.

    Mosquitos - These guys have always been the biggest problem for me. In the past I've used deet products, but I've been in search for a non-toxic alternative that really works for a long time. Citronella candles work ok when you're staying within a couple feet of them, but then as soon as you walk away the blood suckers attack. Another alternative I've tried is eucalyptus oil. It works well but leaves my skin feeling really greasy after a while.Recently my friend let me in on his secret weapon, Vitamin B1. Apparently it is a natural repellant and I had great results when i tried it in a patch form that I found at http://www.greenhome.com
