Six animals most people treat as pests. Here's what an exterminator would charge to replace each one.
BAT — A single bat eats hundreds of mosquitoes and other flying insects per night through the summer. Commercial mosquito fogging for a suburban property runs several hundred dollars per season. The bat does it nightly, from May through September, for free.
TOAD — One American toad eats roughly a hundred insects per night — slugs, cutworms, beetles, ants. Slug bait costs money per application and requires reapplication after rain. The toad is self-sustaining. 🌿
BARN SWALLOW — An aerial insect specialist. A single barn swallow catches hundreds of flying insects per day — flies, mosquitoes, gnats, beetles. Fly control in agricultural settings is a recurring line item. The swallow nests in the barn and works the air column from dawn to dusk.
GARTER SNAKE — Eats slugs, earthworms, and small rodents. Non-venomous, docile, and present in most suburban yards. Rodent control pricing starts in the hundreds for a single visit. The garter snake patrols continuously.
GARDEN SPIDER — A single orb-weaver web catches dozens of flying insects per day — moths, flies, mosquitoes, gnats. The web is rebuilt every morning. No chemical input. No application schedule.
CENTIPEDE — The house centipede is a predator of cockroaches, silverfish, moths, and other household insects. Pest control for cockroaches is among the most expensive recurring services. The centipede does it for the cost of being left alone.
🐾 The common thread:
Each of these animals is killed, removed, or driven off by homeowners who then pay for the service the animal was providing. The exterminator replaces a free system with a recurring bill.
Six invoices. Six animals that cancel them. The math isn't close.
