Using a vacuum cleaner on a large spider is a common and relatively safe method for capturing and removing the spider from your immediate area. Here's what would likely happen if you used a vacuum cleaner on a large spider:
Capture: When you turn on the vacuum cleaner, the suction will draw the spider into the hose or the vacuum's collection chamber. The spider will be trapped by the force of the airflow.
Containment: Once inside the vacuum cleaner, the spider will likely be unable to escape, as the vacuum's design is meant to prevent debris from exiting.
Asphyxiation: Spiders breathe through tiny openings called spiracles located on their abdomen. The strong suction and the lack of air circulation inside the vacuum will likely lead to the spider's asphyxiation over time.
Removal: After capturing the spider, you can turn off the vacuum cleaner, detach the collection chamber or bag, and dispose of it safely, ensuring the spider cannot escape.
It's essential to note that using a vacuum cleaner is a humane method for removing spiders and other insects from your living space. It avoids direct contact, which can be useful when dealing with potentially harmful or venomous spiders. However, if you're dealing with venomous spiders or are unsure about the type of spider you're encountering, it's better to exercise caution and avoid any potential risks.
If you prefer not to harm the spider and want to release it outside, you can remove the vacuum cleaner's collection chamber carefully and release the spider in a suitable outdoor location away from your living space.
