Frequently Asked Questions

Common questions about pest controllers in Castle Hill.

Who are the best pest controllers in Castle Hill?

We've ranked the top 43 pest controllers in Castle Hill, NSW based on our composite reputation score combining Google ratings, review volume, and online presence. Our rankings are updated daily.

How do you rank pest controllers in Castle Hill?

Each business gets a reputation score out of 100 from three things: its Google star rating (up to 47 points), how many reviews back that rating (up to 35), and whether customers can reach it via a website and phone number (up to 18). Review volume is the one part that can subtract: below 15 reviews it costs points, because a near-empty review record gives a stranger very little to go on. No score falls below 0, nothing else is counted, and placement cannot be bought. The score measures the strength of a business's public review record rather than the quality of its work, so it is worth reading the reviews as well — every listing links to them on Google.

Why does a pest controller with all 5-star reviews score lower than one with a lower rating?

Because review volume counts as well as rating, and below 15 reviews it counts against you. Five perfect reviews are encouraging but thin evidence; three hundred reviews averaging 4.7 tell a stranger far more about what to actually expect on the day. That is a judgement about how much proof exists, not about the quality of the work, and a newer business with a handful of excellent reviews may still be the right choice. The star rating and review count sit next to every score so you can weigh both yourself.

Why does the same business not appear several times?

Some businesses run more than one Google listing, often one per suburb they service. Those are the same company, so we group them and show the business once, using the listing with the strongest review record.
