Signs of a Termite Infestation to Watch Out For




Termites have been rated as one of the most ravaging pests in homes. Although the climate in Canada is colder, thus lowering the risk of infestation throughout the year as opposed to in warmer areas, termites are in no way nonexistent. Some forms of it, like the subterranean termites, can live and prosper in most areas of the country, particularly in regions that do not have harsh winters, like the gentle coast of British Columbia or the GTA in Ontario. Termites may cost you thousands of dollars in structural damage before you even become aware that they are present, especially when they are not detected.



Understanding the signs of a termite infestation is your first line of defence. The sooner you notice their existence, the simpler and cheaper it is to get rid of them and restore the damage.



In this detailed guide, we will discuss the nature of a termite, the most common indicators they leave behind, their habits in Canadian weather and what you should do if you think you have an infestation.




About Termites in Canada


It is good to know your enemy first before you are able to detect infestation. These are small insects with a soft body that eat mainly on cellulose, which is the basic compound of wood. Although they are good in the sense that they decompose dead plant materials, they would be a nightmare when they shift to your home's wooden structures.



The common species in Canada are:




  • Subterranean termites- These colonies make mud tubes to travel to and from their nests and food.




  • Dampwood termites- These are found in damp and already-decaying wood, usually along the beach or other damp places.




  • Drywood termites- Rarely found in Canada, may be imported as part of wooden furniture or other wooden material.



All types of termites have somewhat different behaviour, yet the three may result in severe damage should the termite infestation be neglected.


Regions with Higher Termite Activity


Though termites exist in most parts of the country, certain areas register high levels of presence, due to their climatic conditions, in addition to the type of soil and buildings.




  • Southern Ontario: Southern Canada, including some Greater Toronto Area, Windsor, and the Niagara Peninsula, is are good area with termites. They are more prone due to urban development, old housing stock, and the gentler winters in these regions.




  • Coast British Columbia: The wet, moderate climate on the Pacific Coast favours populations of dampwood termites, especially on Vancouver Island and coastal communities.




  • Southern Manitoba: Smaller-scale infestations of occasional subterranean termites have been reported to occur around Winnipeg.




  • Southern Regions of Quebec: Warmer areas of Quebec, e.g. Montreal with its suburbs, present conditions under which termites can survive, especially when they are found in old wooden houses.



In case you reside in any of these more likely areas, a regular inspection coupled with preventative controls is highly recommended.


Termite Behaviour in Canadian Climates


Termites in Canada are more active in warmer months and inactive in the coldest months of winter, although in heated houses and basements, they may feed throughout the year.



These are some of the main details concerning their activity patterns:




  • Seasonal Swarming: Most swarming infestations of termites in Canada occur later in the spring or the summer when things heat up.




  • Moisture Dependence: Subterranean termites live and flourish in a moist environment, where they put leaky homesteads and homesteads with poor drainage at risk.




  • Urban Risk Zones: Older housing stocks or those towns along water bodies normally have increased levels of termites.


Why Termite Infestations Are Difficult To Detect


Termites are referred to as silent destroyers since they operate quietly. They may spend months, years burrowing through wood and soil and make no contact with people. As opposed to carpenter ants, which are very vocal and cause the wood to have obvious heaps of sawdust, termites feed the wood inside out, leaving the surface until the structural damages are so serious.



In most instances, this is realised when visible symptoms of the infestation have set in, and thus there is a high probability that substantial structural damage has already been caused. That’s why knowing the early signs of a termite infestation is crucial for homeowners.


Factors That Increase The Risk Of Termite Activity


Although termites may end up in virtually all premises, some circumstances make them more likely to arise:




  • Contact with the soil at the foundation 




  • Unsafe ventilation in crawl spaces and basements




  • Wood rot, water leaks in pipes or gutters




  • Firewood piled right up to the house




  • Unstained wooden decks/fences



Dealing with these risk factors is a preventive measure in overcoming the likelihood of having a termite issue.




Early Signs of a Termite Infestation


The secret clues that show that termites may be near or inside your residence:




  1. Mud Tubes Along Walls or Foundations



Subterranean termites construct pencil-sized mud tubes of soil, wood particles and saliva. The tubes defend them against their predators and keep their surroundings wet during their journey between their nest and the wooden setting.



They will be found commonly over foundation walls, within crawl spaces or within basements. When facing live termites within a mud tube that you opened up, you can count on having an active infestation.




  1. Burned Wings Close to Windows and Doors



When the termites have grown up, they reproduce winged swarmers (alates) whose duty is to form new colonies. Having swarmed -normally during spring or early summer in Canada- they lose their wings.



When piles of fragile, homogeneous wings are found around windowsills, door frames, or in lighting fixtures, it is a high-quality indicator that a termite colony is close.




  1. Hollow or Papery-Sounding Wood



Since termites eat what is on the inside of the wood and leave the outer cover to seem fine, your wooden furniture could be hollow in the interior while still having the outer appearance that it is fine. When you tap on the wood, beams, floors or furniture and they sound hollow or papery, termites may be causing the problem.




  1. Scruffed Paint



Feeding may produce moisture, and paint may bubble or peel as a result of termite damage. This may also be a result of water damage, but it may be worth checking out in case you observe other signs, too.




  1. Snug Doors and Windows



When termites eat up the wood used in frames of doors and windows, the wooden material may warp, so doors and windows will be difficult to open or close them. Once again, this also may be simple humidity, but with additional symptoms, it may mean termites.


The Importance of Early Detection


The early detection of termites will save thousands of dollars from being spent on repairs. Pest control professionals believe that a termite infestation that is not treated may lead to structural problems that affect safety and the value of a property. Termite insurance is generally not provided in Canada, and therefore, it is even more crucial to watch out.




Advanced Signs of a Termite Infestation


In case termites have already lived in a long period, you are likely to observe more severe warning symptoms:





  • Termite Droppings (Frass)




Drywood termites leave a trail of frass- small wood-coloured sawdust-like pellets. Drywood termites do not occur frequently in Canada, but they can be found in coastal locations or imported on infested furniture.





  • Visible Tunnels in Wood




In case wooden structures contain grooves or channels visible in case of damage or separation, it is highly possible that termites exist. Subterranean termites usually make maze galleries on and in beams and floorings.





  • Sagging Floors or Ceilings




When the damage is extensive, colonisation of the termites may weaken the structural supports, thereby producing floors that will become slanted or ceilings that will bow. It is a serious level of the infestation, which may involve not only the elimination of pests but also significant improvements.





  • Crumbling or Damaged Wood




Severely infested wood is easy to break with fingers or even crumple. You can see this on skirting boards, support beams or furniture made of wood.





  • Sounds in the Walls




You may notice faint sounds of gentleness, clicking, rustling objects in the walls in calm settings. Termite soldiers head-bang as an alarm signal against wood, and termite workers make gentle feeding clicks.




Identifying A Termite Infestation


Seeing one or two symptoms is not necessarily a guarantee because other insects can result in similar symptoms, not to mention environmental factors. You can, to be sure:




  • Scrape or probe with a screwdriver: Gently probe suspect wood to see how it feels; verify hollow places.




  • Employ a moisture meter: Termites can be detected by the level of moisture in wooden structures, which is high.




  • Get a professional inspection done: Pest control professionals come equipped with such tools as thermal imaging cameras to help find signs of termite activity on the inside of walls.




What to Do If You Suspect Termites



  • Do not disturb them a lot- Breaking the wood or tubes may make termites move away and become harder to treat.




  • Contact a certified pest control company- Licensed people can survey the extent of the problem and advise on the treatment method.




  • Think prevention measures- Preventive measures would help, even though termites have been eliminated, so that future intrusions can be prevented.


Treatment Options in Canada


Canadian professional termite control services have the option of using:




  • Liquid termiticides - These are put on the ground in order to establish a fence around the house.




  • Bait stations - Isolate termites using cellulose and low toxicity, barely acting as an insecticide that is transferred throughout the colony.




  • Direct wood treatments - Injection or spraying of chemicals into the wood that is already infested.



There are treatment methods that need to be checked only after a year to guarantee the efficiency of the treatment.


Termite Prevention Tips



Although you may never have had termites, prevention pays in time, stress and cash:




  • Clean gutters and downspouts to avert water puddling.




  • Replace crawl spaces with good, ventilated areas and attics.




  • In place of your home, keep a distance of 20 feet between the store firewood.




  • Perfect time of annual professional inspections, especially on the high-risk venues.




Professional Inspection and Treatment Insights


When you suspect any termite activity, the safest thing to do is to hire a licensed pest control specialist. This is what to look out for:




  • Full Inspection - Termite inspectors go into the basement, crawl spaces, attics, external ones, etc, searching to see evidence of termites.




  • Moisture Testing - They measure the level of humidity in susceptible locations.




  • Recommended Treatments - This may include soil-applied termiticides, bait systems, or direct wood-treated wood preservatives.




  • Follow-Up Visits - Various companies then offer follow-up with the aim of clearing up colonies completely.



Prices in Canada depend on the nature of the infestation and the method of its treatment, although preventative schemes can be as low as rehabilitating structural damages.




Final Thoughts


In Canada, termites might not rank high in comparison to those of tropical environments, but the danger is grave nonetheless. Recognising the signs of a termite infestation, from mud tubes and discarded wings to hollow-sounding wood, can help you act before the damage becomes severe. Periodic checks combined with prophylaxis and timely assistance by specialists are the key to the prevention of these quiet killers at home.



The point is to act early. The earlier you realise the red flags, the more likely you will be able to reduce the costs of fixing the problem and make sure that your property remains structurally sound throughout the coming years.
