Pest Control Services in Delaware, Maryland and Pennsylvania

For more than 50 years, Diamond Pest Control has helped homeowners and businesses across Delaware, Maryland, and Pennsylvania deal with the pests that show up uninvited. We are a family-owned and operated company, and every technician we send to your property is licensed, trained, and focused on solving the actual problem rather than just spraying and moving on. Below is an overview of the pest control services we offer, along with what to expect from each one.

Every service starts the same way: a free inspection and a free written estimate, so you know exactly what you are dealing with and what it will take to fix it before you commit to anything.

Ant Control

Ants are one of the most common calls we get, and one of the most misunderstood. Spraying the ants you can see on a countertop does nothing to the colony feeding, breeding, and growing somewhere else on your property. Our technicians identify the species, locate the nest, and use targeted baiting and treatment methods that eliminate the colony at the source. Visit our ant control page for a full breakdown of the species we treat and how we treat them.

Bee, Wasp, and Stinging Insect Control

Bees, wasps, hornets, and yellowjackets each require a different approach, and getting that wrong can mean an incomplete removal or an unnecessary risk to a beneficial pollinator species. We handle honey bees, carpenter bees, bumble bees, paper wasps, hornets, and yellowjackets, with treatment plans built around the species and the location of the nest. Learn more on our bee control page.

Termite Control

Termites cause more structural damage every year than fire and storms combined, and the damage is often invisible until it is extensive. We inspect for signs of termite activity, including mud tubes, damaged wood, and swarmer activity, and recommend treatment options designed to protect your home’s structure long term.

Rodent Control

Mice and rats contaminate food, chew through wiring and insulation, and multiply quickly once they find a way inside. Our rodent control service includes inspecting for entry points, setting up an exclusion and trapping plan, and identifying the conditions that are inviting rodents onto your property in the first place.

Cockroach Control

Cockroaches spread bacteria, trigger allergies and asthma, and are notoriously difficult to eliminate with over-the-counter products alone. We use targeted baiting and treatment methods that address both the roaches you see and the ones hiding in cracks, voids, and other spots you cannot reach.

Flea and Lice Treatment

Fleas can take over a home quickly once they establish themselves in carpets, furniture, and pet bedding, and lice require careful, targeted treatment to fully resolve. We treat the infestation at every life stage so the problem does not simply reappear a few weeks later.

Spiders, Silverfish, and Occasional Invaders

Spiders, clover mites, silverfish, millipedes, boxelder bugs, earwigs, and crickets are often seasonal or conditional pests that move indoors looking for food, moisture, or shelter. We treat the current activity and address the entry points and conditions that are drawing these pests inside.

Residential and Commercial Pest Control Plans

Every property is different, which is why we offer more than one way to work with us:

•       One-time treatments for a specific, isolated problem
•       Tri-annual service plans with three visits a year to keep common pests from returning
•       Monthly programs for properties under heavier pest pressure, including many commercial accounts

Whether you need a single visit or an ongoing plan, we will recommend the option that actually fits your situation instead of the one that costs the most.
