Being a city of animal lovers and along with its sandy soils and hot climate, Perth experiences huge flea problems. Added to this is its healthy rental market whereby there is constant movement and changeover of pets. With the vacation of resident dogs and cats, any fleas left on the property will await new hosts.

The Bubonic plague that killed millions of people throughout Europe was spread by fleas. Fleas are covered under both Pest Packages.
