Cockroaches are common household pests that can quickly become a nuisance. They contaminate food, leave behind droppings, and emit unpleasant odors. While not inherently dangerous, they can exacerbate allergies and asthma symptoms.

Spiders are common arachnids found in homes and gardens. While most spiders are harmless and beneficial as natural pest controllers, some species like the Redback or Funnel-web spiders can deliver venomous bites.

Bees are generally beneficial pollinators, but their presence near homes or structures can be a nuisance or safety concern. Agitated bees may sting if they feel threatened, posing risks to individuals with allergies.
