Don’t Let the Bed Bugs Bite: Bed Bug Prevention and Non-Toxic Eradication

“Bed bugs” are small nocturnal insects that feed on blood. (Cimex lectularius is the most common species of bed bug.) Some people who are bitten by them get itchy welts on their skin. However, the bugs have not been found to transit any diseases to humans.

Bed bugs are typically found on mattresses, box springs and bed frames, bedding, clothing, and in any dark cracks, seams, or crevices in beds, furniture, walls, or floors. They can travel through water pipes, wall voids, and ducts, and can spread from room to room.

Adult bed bugs are about 1/4-inch long and 1/8-inch wide; younger ones are smaller (often about 3/16 of an inch long or the size of a pinhead). They have flat, grayish-brown or reddish-brown bodies with six legs, and after feeding, they become round and red. They give off a sweet, musty odor. Their eggs are white and very small, and their excrement appears as tiny brown or black spots, which can look like small blood stains if smeared.

Here are some rules for prevention, as well as tips for getting rid of bed bugs if they do appear.

Keeping Bed Bugs Out

  • Consider getting a protective plastic cover for your mattress(es) and box spring(s) to keep bugs out/off of the bed. Tape up any tears or holes that appear in the mattress, box spring, or plastic covering.
  • Eliminate excess clutter (particularly near your beds and clothing), to reduce the number of places where the bugs can hide.
  • If you have been staying elsewhere or traveling, check your luggage and belongings for bed bugs before bringing them inside. Unpack your clothes directly into the laundry and wash everything with hot water.
  • If you are considering buying any used/second-hand items, check them carefully for bed bugs before buying them, and wash them before bringing them into your home.

Getting Rid of Bed Bugs

While some pests can pose health concerns for building occupants, so can many pesticides. Pesticides and insecticides are poisons, and as such they are often poisonous to humans (and pets) as well as to pests. Studies have linked some pesticides to cancer, birth defects, neurological disorders, and immune system disorders, as well as allergies. Therefore, pesticides should only be used as a last resort.

If the steps below are not sufficient to eliminate a bed bug problem and an insecticide must be used, ask an experienced professional to recommend the least-toxic insecticide that will be effective, and have it applied by a professional who will take safety precautions. The bed bugs’ eggs are not affected by insecticides, so the treatment will probably need to be applied several times to kill the hatchlings. Note: Bed bugs have become resistant to some pesticides, and using harsher pesticides could just end up making the bugs stronger, as they could build up resistance to those.

If you want to research insecticide options on your own, check out the EPA’s Bed Bug Product Search Tool.  As a general rule, avoid products that are labeled “Danger—Poison,” as those tend to be the most toxic to humans. Never use pesticides indoors that are intended for outdoor use. And don’t use (or allow others to apply) any product that does not specifically list bed bugs on the product label. Some sticky traps are designed for bed bugs. (Note: Baits for ants and cockroaches will not work on bed bugs.)

But before using any pesticides/insecticides, first try these non-chemical strategies:

  • If you think you’ve found bed bugs, first make sure that’s what they are. Have a professional identify them, or using a flashlight and ideally a magnifying glass, compare the bugs to photos of bed bugs to make a positive identification. (There are many websites with close-up photos of the bugs. Just do an online search for “bed bug” images.)
  • Infested materials can be rid of bed bugs by being heated to at least 113 degree for an hour (or by being frozen at less than 0 degrees for at least 4 days). Many bed bug extermination services now use cryogenic freezing methods (e.g. the Cryonite system) to kill the bugs.
  • Wash your bedding and clothing with hot, soapy water, and dry them on the hottest dryer setting.
  • Vacuum cracks, crevices, and other hiding places in walls, floors, and furniture where adult bed bugs or eggs are found. Dispose of the vacuum contents right away in a sealed trash bag, in an outdoor garbage bin.
  • Use hot, soapy water to wipe all surfaces and crevices where the bugs might be living.
  • Seal up any cracks where the bugs are living. Seal/tape up any tears in mattresses or other areas where the bugs could hide.
  • Eliminate excess clutter (particularly near your beds and clothing), to reduce the number of places where the bugs can hide.
  • Try sprinkling food-grade diatomaceous earth in areas where the bed bugs have been seen, to prevent them from hiding in those places again. (Food-grade diatomaceous earth can be found at many feed stores, garden centers, or hardware stores.)
  • If a mattress or box spring is infested with bed bugs, it will probably need to be disposed of (unless the entire thing can be put into a large freezer), as the bugs can live inside the mattress where they can’t be reached. Mattresses should never be treated with insecticides, unless a specialist verifies that the treatment is non-toxic to humans. Infested mattresses should never be donated, but can be recycled. When disposing of a mattress or other infested objects, deface them so that others will not be tempted to take them home.
  • Tightly wrap in plastic any infested possessions (including mattresses) before carrying them out of a room for disposal, to avoid spreading the infestation to other rooms.

Consult with a licensed, experienced pest control professional for further advice and treatment options.

Flea and Tick Treatments That Won’t Poison Your Pet

Fleas and ticks (and mosquitos) can bring severe itching, allergic reactions, discomfort, and even serious diseases (such as lyme disease) to your pets, so it’s important to protect your pets from them. However, studies have found that some common flea and tick control treatments—products that are readily available at stores and have been recommended by many vets—aren’t just harmful to fleas and ticks; they can actually poison pets, and some are also dangerous to humans and other animals.

Some conventional flea and tick treatments (including many of the topical, spot-on treatments that are applied directly onto pets’ skin, as well as flea collars, powders, and sprays, and even some ingestible products) contain highly toxic pesticides, some of which have been shown to cause a range of serious reactions in pets, from skin problems, vomiting, and excessive drooling to neurological problems (e.g., seizures or uncontrollable shaking), heart attacks, and death. So, tragically, some pesticides end up serving as pet-icides…

The Center for Public Integrity did a study in 2008, and found that at least 1,600 pet deaths related to spot-on treatments were reported to the EPA over the previous five years. According to the NRDC, cats may be more susceptible to adverse reactions than dogs, since they are more likely to lick the treatments off of their fur and they often lack enzymes for metabolizing or detoxifying the pesticides. Many of these pesticides are toxic to humans, as well, and children are especially vulnerable to exposure.

Avoid products that contain pyrethroid, pyrethrin, or permethrin pesticides, organophosphate insecticides (such as tetrachlorvinphos/TCVP; chlorpyrifos, dichlorvos, phosmet, naled, diazinon, and malathion), carbamates (e.g., propoxur, fenoxycarb, and carbaryl), or Amitraz. [This list was updated on May 26, 2010.] Many common flea/tick control products contain at least one of these ingredients. (Towards the end of this post, you will find a link to a listing of some specific products to avoid.) Please note: Never use products on cats that are meant for use on dogs (and vice versa), and never give your pet more than the recommended dose.

It’s disturbing that so many of us might have been unwittingly sickening our animals (and possibly shortening their lives) by using these products, often at the recommendation of our veterinarians, who trusted the manufacturers’ assurances of the products’ safety. It’s yet another example of how you can’t trust that a product is safe just because it’s been allowed into the marketplace. According to the Humane Society, the EPA did not start reviewing pet products for safety until 1996, and there is still a backlog of products that need to be tested. However, the overarching problem is that some ingredients that the EPA had deemed “safe” clearly were not. In 2009, the EPA announced that it would be developing stricter testing and evaluation requirements and could place new restrictions on flea and tick products.

Fortunately, there’s no need to wait for those changes to take effect. Safe and natural alternative products and methods for controlling fleas and ticks already exist. Here is some guidance from the NRDC on ways to prevent flea problems. And when treatments are necessary, some pet supply stores and many online sites (see links below) now carry flea and tick products that are made up of plant-based ingredients, such as peppermint oil, citrus oil, clove oil, or Neem, which is a natural insecticide that comes from a tree. See the NRDC’s Flea and Tick Product Directory to look up the ingredients and risks of specific products. Some flea and tick solutions can even be made at home. Fleas and ticks are repelled by rosemary, thyme, eucalyptus, and lavender. So to ward off the bugs, you can tuck sprigs of one or more of those plants under your pet’s bed cover (or under your rugs), or boil some of those herbs in water and pour the cooled water onto your pet, rubbing it into their coat. (Note: Some herbal or “natural” ingredients can cause allergic reactions or toxicity in animals. Be sure to test any treatment in a small dose first; and always apply treatments sparingly and only as needed. Also, never use pet products that contain pennyroyal oil, which is toxic to animals. Furthermore, while some sources say that adding a little bit of garlic to a pet’s diet will repel fleas, other reputable sources say that garlic can be toxic to dogs and even more so to cats, even in small amounts; so I steer clear of using garlic, just to be safe.) If your pet has a flea infestation that does not respond to any of the plant-based solutions listed above, look for the lowest-risk commercial products listed in the NRDC’s directory, which include Spinosad-based products, such as Comfortis.

NRDC’s research has identified many common products that should be avoided, due to their high toxicity risks. According to the NRDC, such high-risk products currently include K9 Advantix II, and a number of products made by Hartz, Sentry, Sergeant, Vet-Kem, Adams, Bio Spot, Happy Jack, Verbac, Zodiac, and other companies.

To take action on this issue, print out some of the info from the links below, bring it to your pet store and to your veterinarian, and ask them to stop selling flea control products that contain the most dangerous pesticides (and to start selling the lowest-risk products), to protect the health of pets and their people.

Sustainable Agriculture in the Spotlight: Fresh films, books, etc.

Building on what Super Size Me and Fast Food Nation did to expose the health problems associated with eating fast food, a veritable cornucopia of new documentary films have recently come out, bringing attention to a broader array of issues related to factory farms and feedlots and to the benefits of sustainable farming and ranching. These films include:

FoodInc-movie_poster

Update (8/13/09): A dozen other important food-focused films have just been highlighted by Serious Eats.

And on Showtime TV, Season 1 of This American Life had a great segment on factory-farmed genetically modified pigs. (The show can be rented through NetFlix, etc. I highly recommend watching both seasons.)

A fresh crop of books have recently been published on these topics, as well, including:

For additional information on sustainable agriculture and good, real food, check out resources such as: Organic Consumers Association, The Land Institute, Roots of Change, Slow Food USA or Slow Food International, Fields of Plenty, Animal Welfare Approved, and Certified Humane.

Please support small, organic farms and your local farmers markets; consider joining a Community Supported Agriculture (CSA) farm or growing some organic produce in your yard or a community garden; and if you eat meat or dairy products, choose products (e.g., Niman Ranch) that come from humanely raised, non-hormone-boosted animals. To sign the Declaration for Healthy Food and Agriculture (from Roots for Change), click here.

An Effective and Non-Toxic Solution for Getting Rid of Yellow Jackets’ Ground Nests

yellowjackets-groundnestI’m not someone who delights in killing pests, and I don’t often advocate for their demise. In fact, I usually do my best to avoid killing them (e.g., if an indoor spider gets too close for comfort, I usually capture it in a jar and release it outside). However, I recently had to make an exception to my pacifist policy, when I noticed that yellow jackets had built a ground nest right next to the front door of our house. It was an underground nest in a flower bed. There were so many yellow jackets coming and going from the nest throughout the day that we were scared to keep our front door open for very long, and I worried that our dog would inadvertently step on the entry to the nest and get swarmed and attacked. Furthermore, I learned that some yellow jackets raid honeybee hives to steal their honey, and they kill honeybees in the process. This was a sufficiently good reason to get rid of the ground-nest jackets, in my opinion. One of our neighbors has a honeybee hive, so it felt like getting rid of these yellow jackets was a just and neighborly thing to do. (Honeybees are suffering from a Colony Collapse Disorder. For info about it, click here. Note: If you have a problem with a swarm, nest, or hive, check out online photos of bees, yellow jackets, hornets, etc. to make sure you know which of these you’re dealing with. Honeybees and other pollinators are extremely important, and they almost never sting; please don’t kill them.)

Update: I have also recently learned some of the ways that wasps, including yellow jackets, also have ecological value and provide ecological balance; for example, they eat aphids (which are the scourge of many gardens). And I’ve learned that the type of yellow jackets that build ground nests is different from the type that builds honeycomb paper-like nests (under roof eaves or elsewhere). The ones that build the above-ground paper nests are not aggressive or interested in human foods (e.g., meat and sugary foods) like the ones that build ground nests. So I leave the paper nests alone. In fact, they built one next to our back door, and those yellow jackets never bothered us at all or even came inside.

Anyway, back to our ground nest problem: I didn’t want to use toxic insecticides, which could kill the flowers in our garden and poison our dog and the honeybees, along with the soil and groundwater around our house. So, thinking we were being clever, my husband and I tried putting the garden hose down the nest entry hole and flushing out the nest with water. This scheme did not work. We tried it a few evenings in a row, and the tenacious buggers would shoot out of the nest alive (seemingly unfazed by the water) and quickly rebuild a new entry hole. One evening, they went into attack mode and my husband got stung. They won these battles, but we were determined to outsmart them and win the war — without resorting to the use of Raid, professional chemical insecticides, gasoline, or any of the other toxic and hazardous substances that are commonly suggested.

drbronnersSo I started researching other non-insecticide solutions. Through my reading, I learned that mint oil can kill almost any insect, and that yellow jackets also don’t like soapy or boiling water… We happened to have a quart-size container of Dr. Bronner’s “magic” organic peppermint castile liquid soap in the house. The bottle was only half full, so we filled the rest of it up with water to make it a 50% diluted quart. Then we waited ‘til it was almost dark outside (this is the only time you should ever deal with yellow jackets, as they’re all inside the nest and inactive at night). We poured the quart down the nest’s entry hole (it’s best to do this with an extension device, like a hose or a gas can or watering can, to keep your body further from the nest opening — and you should also wear protective clothing). We immediately followed that up by pouring in a kettle full of boiling hot water, which washed the mint oil further down into the nest. We didn’t see a single yellow jacket emerge from the nest that night, and we haven’t seen any around here since. It worked!

RECIPE
1/2 quart (2 cups) Dr. Bronner’s organic peppermint castile soap, diluted/mixed with
1/2 quart (2 cups) water [poured into the nest via a hose or watering can with a long nozzle, at dusk or at night]
Followed by 1 tea-kettle full (approx. 1 quart or 4 cups) of boiling water

[NOTE: While this solution worked for this ground nest, it probably is NOT appropriate—and could be a dangerous method to try—for other scenarios, e.g., nests in the walls of your house, where you cannot find the exact entry spot. For those types of situations, try using Rescue traps or making a homemade soda-bottle trap instead.]

Dr. Bronner’s entertaining, pontificating text-filled label (I recommend reading all of the fine print if you haven’t before) states that the soap is good for 18 different uses: from washing pets and babies to washing dentures and cars. Yellow jacket / insect eradication isn’t one of the listed uses, but it seems that it should be. Soon I’m going to experiment with using the stuff to repel mosquitos, get rid of ants, and keep fleas and other bugs off of the dog.
