Don`t let the bedbugs bite

Bed Bug on mattress
Spying a beautiful mattress abandoned by the roadside near her home, Nadia did not take it as a warning. It looked clean and relatively new, so she took it for her apartment. She lugged it up the steps, into her home in the Montreal Plateau, dragging it towards her bedroom. Then she happened to glance down and notice the felt marker writing, scrawled on the back-side of the mattress: BEDBUGS!

With bedbugs on the rise in many major cities, the bedbug has become the new bogey monster, haunting the media, and appearing in unexpected places like the cinema, the airport, and even the workplace. But is the scare really justified? Bringing the subject up to my grandfather, who had dealt with bedbugs prior to DDT, he chuckled and agreed they were a pest; it took 3 months cleaning to be free of the nuisance. Yet many recent cases, employing modern pesticides have offered less results. `The exterminator has sprayed five times already, and we`re still getting bitten. It`s been five months now. I`m really sick of this!“, said Dominic, a Montreal tenant, echoing the complaint of many apartment dwellers. When it comes to de-bugging, it is important to be well informed, and to engage a knowledgeable company, one that does at least two visits, and will take measures to prevent re-infestation from neighbouring living spaces. While bedbugs do present cause for concern, we should be able to travel, go to the movies, stay at hotels, hostels, and friends` homes without constantly worrying about catching the bug. It is possible to decrease the risk by taking some precautions.

• Make sure not to pick up any infested materials, such as furniture or electronics. Inspect items carefully before bringing them into your home. It is not advisable to pick up used mattresses.
• Keep in mind that bedbugs can be found in many places of transience, such as hotels, hospitals, residences, airports, and movie theatres.
• Keep luggage away from walls and furniture when staying somewhere that may be infested. Luggage may also be protected by placing in a garbage bag, tied shut.
• When returning from travels, do not bring backpacks and suitcases directly into the house. Bag items before taking them in. Any materials that can be machine washed or dried, wash them hot, and/or place them in the drier. Depending on the material, some bags and suitcases can be cleaned with a steam cleaner.
Infestations can begin with a single bug, so it is important to be thorough when dealing with this problem. Detection dogs, dogs trained to sniff out the offending critters, are able to pick up on bedbugs when even experts have trouble detecting low levels of infestation. If you think you have bedbugs at home, there is no need to use conventional pesticides. From our experience, many pesticides can aggravate a problem by causing the bedbugs to disperse, spreading throughout a building. A steam cleaner can be an invaluable tool in the fight against bedbugs, as it can be used to treat the mattress, bedframe, and other materials in the room. Bedbugs are very sensitive to heat and at just 46⁰C will die in less than 10 minutes! From our experience, steam treatment and heat treatments are the best approach, as they target even the eggs of the bedbugs, which most pesticides cannot do. Unavoidably, a bedbug infestation means time for some serious cleanup. Clutter will need to be removed and often much clothing and bedding needs to be washed hot, and dried to get rid of the bugs. Below are some tips for dealing with an infestation:

• Treat cracks and crevasses in room with diatomaceous earth. This can be found at the hardware store under the names Insectigone, or Insect Stop.
• Use a steam cleaner on your bedframe, especially to clean joints and screw-holes. Your mattress and furniture, if appropriate, may be cleaned with the steam cleaner. Note that dry steamers are often recommended.
• Use a zippered mattress cover for your mattress and box-spring
• Apply petroleum jelly around legs of bed. Place bowls, or trays under each leg of bed and fill with diatomaceous earth. See our site for more information: www.ecobugdoctor.com

When Nadia realized she had brought bedbugs to her apartment, she immediately threw out the infested mattress, washed her clothes and took a shower before cleaning the hallway she had dragged the mattress through. Luckily she saved herself from an infestation, and a visit with our bedbug detection dogs confirmed that no bedbugs were present. While bedbugs are a major problem, they can be overcome without using conventional pesticides, through thorough cleaning and use of ecological products. Though there is much debate as to the best ways of dealing with bedbugs, one thing bedbug experts can agree on is that it is much easier to prevent an infestation than it is to get rid of the critters once they are established.

Bug Free, Naturally

A Healthy Home is the Best Solution to Pest Problems
Pest problems can be resolved permanently, without using pesticides, by repairing leaky plumbing, and other structural deficiencies.

Using pesticides of any kind to kill off insects, such as sow-bugs, millipedes, silverfish or carpenter ants that have invaded your living space is much like using perfume to remedy a garbage spill. It may show immediate results but it is, by no means, a long-term fix. The reason being that unwanted pests in your home is usually a sign of structural deficiencies and until these deficiencies are addressed, the pest problem will keep coming back.

Back when city by-laws were first being enacted to protect people from pesticides, Paul Maloney, my father, and the original Eco Bug Doctor, got a memorable call at our office. A woman, a medical doctor, in fact, was upset by the fact that she was not allowed to use pesticides to get rid of the carpenter ants around the doorway of her home. Paul assured her that he could help the ant situation and although she was skeptical that a ‘soft’ ecological approach would have an effect, she agreed to a home visit.

An inspection of the ant-infested area revealed that water was seeping into the bottom of the wooden door frame, creating the perfect living environment for these wood-recycling ants. By finding the source of the problem, Paul was able to solve the problem, without the use of potentially harmful chemicals. The doctor was sufficiently impressed that she began promoting ecological solutions, discouraging friends and neighbors from using unnecessary toxic chemicals.

Water is the substance from which all life arises, but if you add water to a solid wood structure, over time, the wood begins to break down, releasing nutrients that allow mould (fungi) to grow. This in turn attracts detritivores (sow-bugs, millipedes, and silverfish), the insects and other small creatures that feed on decomposing matter. Then, to complete the ecosystem, the predators move in, the centipedes and spiders, that feed on the detritivores, just like wolves hunting rabbits. If you protect this wood from water infiltration and dry out the area, you will put an end to this miniature ‘ecosystem’ and permanently solve the moisture-bug problems in your house.
There’s another positive side-effect to this ‘ecological’ approach to ridding the home of pests; it may also rid the home of mould, which like man-made toxic chemicals, can trigger a host of symptoms, discomfort and health problems, including allergic reactions, asthma symptoms, irritant effects, headaches, respiratory problems and problems concentrating, etc. There is also good evidence that mycotoxins can be carcinogens, immune suppressants and neurotoxic agents. According to Dr. Schaller, author of many books on mould and illness, the most common cause of learning disorders and behavioral problems in children and adolescents that he has treated has been indoor mould contaminants.

Mould is usually not visible to the naked eye, and doesn’t always smell, although we are all familiar with the musty smell mould does give off. Washington’s Institute of Medicine, a non-profit advisory group, affirms what we have been telling clients for years: in order to prevent mould and associated creatures (such as sow-bugs) in a building you must keep materials dry, or use building materials that offer a poor substrate for growth in places where moisture is unavoidable. As we have found, in remedying a sick building, the task may seem daunting, but with a bit of creativity, lower-cost solutions can be found for addressing a whole host of structural deficiencies.

Carpenter ant nests are typically found where there is rotten wood

Here are some things to look out for, to uncover a carpenter ant problem:

 Big, black ants indoors (especially during cold weather)
 Piles of fine sawdust
 Trails of ants, or ‘ant highways’ on power lines leading to your house
 Trails of ants on outside walls of house (often you can find them by going out at night with a flashlight)

Wasp Season

Yellow Jacket WaspWasp season has arrived! Along with the blackberries, brown-eyed-susans, and construction holiday, the wasps are right on cue. Truth is they’ve been around for quite awhile, since early May, building their beautiful paper nests from scratch. But its only in recent weeks that most people notice, because ‘Whoa!’, now the nests are visible!

In early spring, the queen wasp is all alone, working hard to build some paper comb so she can lay eggs, then catching insects to feed to her larvae. These larvae grow to become the worker wasps that will continue to build the nest for her. Once the workers are in place, the queen just has to concentrate on making babies…and lots of them! Did you know that a yellow-jacket wasp nest, by the end of the season, can have up to 5000 wasps? At this point, the nest could be protected by up to 10 layers of paper! These layers are carefully constructed by the workers, who collect wood fibers from weathered wood decks, wood siding and other sources, mix it with their saliva and spit it out to make paper. You might notice streaks of colour, like greens and blues in some nests. That’s because the wasps took painted or stained wood fibers from a house and incorporated it into their nests!

Wasps are great predators and will remove many ‘pest’ insects from a yard, such as plant-feeding leaf-hoppers and caterpillars, among others. They also feed on spiders. Often if a visible nest is very high up in a tree or on a structure, it is perfectly safe to leave it. True, it may bring more wasps to the barbecue during an outdoor party, but generally it is a minor nuisance, unless someone is allergic. One particularly dramatic case had the wasps coming out into the baby’s room. We had to seal the walls in the little guy’s room before we went to remove the nest from near his window. When the wasps enter a house, they are not generally aggressive, but wander around, appearing rather lost. Still, their presence is often far from appreciated!

Honey Bee Fever

Honey Bee Larvae EcoBugDoctor

Workers inside the colony, tending to honey bee larvae

It’s a gorgeous day, the snow is melting, and critters are starting to emerge from their winter daze. I sure felt like one of them, blinking like an owl in the sudden sunshine outside. A visit to the apiary confirmed that our colony of honeybees has survived the winter. Wooohooo! It’s an amazing sight seeing them buzzing to and fro, it being just barely March! All in all, a good day for starting a blog, writing about our adventures as entomologists and some of our experiences working in the field of ecological pest control. I’d love to share some stories, tips, AND excitement about working with insects and wildlife, doing our detective work, and coming up with natural ways to help people out with their uninvited-creature problems.

Since I mentioned the honey bees, I think this would be a nice first post. Honey bees survive the winter by moving close together within the colony, forming a cluster. This cluster will expand or dilate, depending on the temperature. In the center of the cluster, where the queen resides, the temperatures are warmest, around 2o° C. The workers bees need to continually rotate, since things are much colder around the fringes of the cluster (~7° C) !

There’s been a lot of concern over the little fellas in recent years because of their decline, and the unsettling phenomenon of Colony collapse disorder (CCD), where worker bees in a colony abruptly disappear without a trace. The role of bees as pollinators makes this decline particularly worrisome; 80% of plant pollination is done by bees and other animals. Bees play an important part in pollinating crops such as melons, apples, blueberries and almonds to name a few.  Though there is no one factor identified as the cause of CCD, there are several theories attributing the problem to infestation by Varroa mites, insect diseases, pesticide exposure, migratory beekeeping practices, and global warming, among others. The combination of such stressors would at the very least weaken the colonies, making them more susceptible to any further attacks. Though we keep our bees on an organic farm, there are many neighboring orchards where pesticides are definitely used. In past years, our colonies have not enjoyed much success,  so this year’s off to a good start, with the bees already flying about ! I’m looking forward to spring, watching them leaving on their heroic ventures to visit a ton of flowers, and retuning with bright orange balls of pollen on their legs.
