For the most part spiders will not attack humans unless they feel threatened. Nonetheless, some spiders around the world are very dangerous to have in your home and can inflict serious injury, or even death, with a single bite to a human. Most of these dangerous spiders are found in tropical climates such as in Australia, South America or Asia.

Although it is less common, even Canada has one particular species of spider that can inflict serious harm to humans. This spider is known as the black widow spider and has even be found in homes around Toronto Ontario. A bite from the black widow spider can leave you in extreme pain for several days, but very rarely will it ever cause death.

If spiders have invaded your home be sure to call a pest control company right away so they can safely remove the spiders and any other pest that is present in your home.


Unlike spiders, termites do not cause direct harm to humans by inflicting injury through their bites. Instead, termites are dangerous to humans as a result of their dietary choice of eating wood, thus causing damage to the interior structure of homes.

Termites are also very social creatures that live in very large colonies and reproduce at alarming rates. Once they enter a home they can go unnoticed for a long period of time, eating the internal wood structure of the home. In many cases, termites are not noticed until it is too late and they have already caused severe damage to a home. Sometimes this damage can even be so severe that it makes a structure fall apart, potentially causing harm to the inhabitants of the home.

Since they are so difficult to spot and get rid of, it is highly recommended to call a termite extermination company upon discovering them in your home.


For thousands of years rats have been a huge nuisance to human populations. They always seem to be around where humans are living, hiding in our homes and eating any food they can get access to.

Rats are considered to be one of the most detrimental household pests in the world due to their tendency to carry disease. The diseases they carry can be spread in a variety of ways such as through biting, scratching, or by contaminating food and surfaces through their urine or feces.

One of the most devastating pandemics in human history, the black plague, which killed off between 30% to 60% of the European population between the years 1346-1353 has been largely attributed to rat infestations during this time.

If you find rats in your home call a rodent control company right away to ensure they are removed as soon as possible.
