Earwigs, also known as pincher bugs or pincer bugs, are a common sight in many Canadian households. These small insects are known for their distinctive pincers, which they use for defense and mating purposes. Despite their prevalence in Canada, many people don’t know when earwigs first arrived in the country. In this article, we’ll explore the history of earwigs in Canada and what you should know about these pests.
Earwigs are believed to have originated in Asia, although they can now be found all over the world. They are commonly found in warm, humid climates and are particularly prevalent in tropical regions. Earwigs can be found in a variety of habitats, including gardens, forests, and urban environments.
Earwigs in Canada
Earwigs were first observed in Canada in the early 1900s. It is believed that they were introduced to the country through imported goods or on ships traveling from Asia. Since their arrival, earwigs have become a common pest in many parts of the country. They are particularly prevalent in British Columbia and Ontario, but can be found in other regions as well.
Earwigs are nocturnal insects and are most active at night. During the day, they hide in dark, moist places such as under rocks or logs. Earwigs are omnivorous and will eat a variety of foods, including other insects, plants, and decaying matter. They are also known to feed on crops and can cause damage to fruits and vegetables.
Preventing Earwig Infestations
There are several steps you can take to prevent earwig infestations in your home or garden. These include:
- Removing debris: Earwigs thrive in dark, moist environments, so removing piles of leaves or other debris can help prevent them from taking up residence in your yard.
- Sealing cracks: Earwigs can enter your home through small cracks and crevices. Sealing these openings can help keep them out.
- Reducing moisture: Moisture is essential for earwigs to survive. Fixing leaky pipes and ensuring that your home is well-ventilated can help reduce humidity levels and discourage earwigs from taking up residence.
Treating Earwig Infestations
If you already have an earwig infestation, there are several treatment options available. These include:
- Insecticides: There are a variety of insecticides on the market that are effective against earwigs. Be sure to follow the manufacturer’s instructions carefully when using these products.
- Traps: Earwig traps can also be effective in reducing populations. These traps are typically placed in areas where earwigs are known to congregate, such as under rocks or in gardens.
