Spiders in your home?

Spiders and predatory pests like centipedes and ants can be a nuisance and even a threat to homeowners in Medicine Hat. These creepy crawlies not only make our living spaces uncomfortable but also pose potential health hazards. At On Guard Pest Control, we are committed to providing efficient and safe pest control solutions to help you reclaim your home from these unwelcome guests.

It's important to remember that spiders and predatory pests, such as centipedes, and ants, do play an essential role in the ecosystem by keeping the population of other insects in check. So before considering control, you need to evaluate their impact on you.  There can be beneficial impacts to having them on your property.

However, when spiders and predatory pests enter our homes, they become a cause for concern. Here are some common species found in Medicine Hat, Alberta:

House Spiders:

These small, brown spiders are often found in dark, secluded spaces like basements, closets, and corners. Though their bites are not usually dangerous, they can be a nuisance and a source of fear for many homeowners.

Black Widow Spiders:

Known for their distinctive red hourglass marking on their abdomen, these spiders are the most venomous spiders in Alberta.  While they can pose a risk to humans, especially children and the elderly, they will only bite if their web is disturbed and they rarely bite humans. However, if they do bite, they can cause severe pain and, in rare cases, may even be fatal if left untreated.


These many-legged creatures often enter homes in search of food and shelter. Remember though, while they may look creepy, they can have beneficial effects by keeping other insects from invading your home.  We understand their presence can be unsettling for homeowners. 


Ant infestations can lead to damage to your property and contaminate your food. Carpenter ants, in particular, can cause structural damage by tunneling through wood.

Spiders and predatory insects are attracted to cluttered and untidy environments, as they provide excellent hiding spots and breeding grounds. Here's how you can maintain a clean home to deter pests:

  • Regularly clean and vacuum your living spaces.  Especially corners and dark spaces under furniture/appliances.
  • Keep your kitchen and dining areas free from food crumbs and spills.
  • Store food in sealed containers and promptly dispose of garbage in tightly closed bins.
  • Declutter your home, especially in basements, attics, and storage areas, to reduce hiding spots.


Preventing spiders and predatory insects from entering your home is crucial in keeping them at bay. Here's how you can create a barrier against these pests:

  • Inspect the exterior of your home for cracks, gaps, and holes, and seal them using caulk or other appropriate materials.
  • Ensure that window and door screens are in good condition and fit tightly, repairing or replacing them as needed.
  • Install weather stripping around doors and windows to prevent pests from entering through small gaps.
  • Maintain your home's exterior by trimming overgrown vegetation, cleaning gutters, and removing debris from your yard.


Employing natural repellents and traps can be an effective way to control spiders and predatory insects without using harsh chemicals. Here's how you can utilize these methods:

  • Use essential oils, such as peppermint, lavender, or eucalyptus, as natural repellents. Mix a few drops with water in a spray bottle and apply around entry points and known hiding spots.
  • Place glue traps or sticky tape in strategic locations, like corners and under furniture, to capture crawling insects.
  • Introduce benevolent natural predators, such as ladybugs or praying mantises, to your garden to help control insect populations.
