Termites
Signs you may see
- Mud tubes along the foundation or walls.
- Wood that sounds hollow when you tap it.
- Discarded wings near windowsills. Swarmers are most active from March to June.
- Buckling paint, bubbling surfaces, sagging floors or doors that stick.
- Small holes in drywall.
What we do about it
- We start with a thorough termite inspection, and it is free.
- We treat the colony, the hidden areas and the entry points, not just the termites you can see.
- Targeted treatments, preventative barrier systems and a long-term protection plan keep them from coming back.

"If that wasn’t enough, they (thankfully) also discovered that I had early stages of termites as well as the start of some mold."

Ants
Signs you may see
- A trail of ants in the kitchen, pantry, bathroom or garage.
- Ants in the crawl space, looking for food and moisture.
- Ants that keep coming back after store-bought sprays.
- In Southern Illinois that is usually odorous house ants, pavement ants, carpenter ants or field ants.
What we do about it
- We find the source of the problem and treat the colony, not just the ants you can see.
- We build a treatment plan for your home that helps stop them coming back.
- Some ants, like carpenter ants, can damage wood over time.

Spiders
Signs you may see
- Webs around windows, doors and cracks.
- Spiders in the basement, the attic or the closets.
- Seeing one, and wondering how many more are hiding.
What we do about it
- We treat your home for spiders as part of a plan built for your property.
- Routine general pest control, quarterly for most homes, helps keep them from settling back in.
"I haven't seen one spider (alive) on my porch since their service on June 19th."

Cockroaches
Signs you may see
- Live roaches in the kitchen, bathroom or basement. Seeing one in daylight often means many more are hiding.
- Small black droppings that look like coffee grounds.
- Egg cases, shed skins, or smear marks along walls and baseboards.
- A musty, unpleasant odor.
What we do about it
- Interior and exterior treatments, targeted baits, and crack and crevice treatments.
- Work to close up entry points, plus advice on the moisture and food that draw them in.
- German, American, Oriental and brown-banded roaches all behave differently, so we identify yours first.
Mice and rats
Signs you may see
- Droppings in cupboards, drawers or along the walls.
- Scratching in the walls or the ceiling.
- Gnaw marks, chewed wires or damaged food packaging.
- Nesting material, or pets acting strangely.
What we do about it
- A thorough rodent inspection to find the entry points, the nesting areas and whatever is drawing them in.
- A customized treatment plan, and long-term prevention so they do not return.
- A mouse can squeeze through a gap about the size of a dime, so we look closely.
"We live on five acres of wooded land and have not had any issues with insects or rodents."

Bed bugs
Signs you may see
- Bites that appear overnight.
- Small blood stains on the sheets.
- Tiny dark spots on the mattress.
- A musty odor, in a severe infestation.
What we do about it
- Treatment that reaches where they hide: mattress seams, furniture, baseboards and cracks.
- We target the eggs and the active bugs, the breeding spots, and the risk of them coming back.
- We treat homes, apartments, hotels and other commercial properties.
Mosquitoes
Signs you may see
- Standing water in pots, bird baths, buckets, gutters or low spots. Mosquitoes can breed in a bottle cap of water.
- Shady, overgrown corners, decks and porches where they rest in the heat of the day.
What we do about it
- Outdoor mosquito treatments that target breeding areas, resting spots in your landscaping and the mosquitoes themselves.
- Routine treatments through the season, so you can use your yard all spring and summer.
Ticks and fleas
Signs you may see
- Finding ticks on pets, kids or clothing after time outside.
- Tall grass, leaf piles, or wooded edges and fence lines near the house.
- Living near fields, woods or trails.
What we do about it
- Yard treatments that target active ticks, breeding areas, shaded zones and property edges.
- Tick and flea treatments that keep your family and pets comfortable.
- Ticks can carry Lyme disease, so we focus on long-term prevention, not a quick fix.
Wasps and hornets
Signs you may see
- A nest in the eaves, in the yard or under the deck.
- More stinging insects around the house as summer comes on.
What we do about it
- A single nest can often be cleared with a one-time treatment.
- If stinging insects come back every summer, a seasonal treatment before their peak helps prevent them.
Damp crawl space
Signs you may see
- A musty smell inside the house.
- Standing water under the house after heavy rain.
- Mold, mildew, damaged insulation or cold floors.
- Rodent or termite activity below the floor.
What we do about it
- Crawl space encapsulation: we seal the space with a durable vapor barrier.
- Moisture control, and mold treatment where it is needed.
- A drier crawl space means fewer pests, better indoor air and lower energy bills.

"They encapsulated my crawlspace and remediated mold and termite damage."

Crawl space encapsulation
Humidity, seasonal rain and temperature swings leave a lot of crawl spaces damp. That moisture feeds mold, wood rot, higher utility bills and pests. We seal the crawl space with a durable vapor barrier so the space under your home stays cleaner and drier.


Spot On never disappoints. I had ants and spiders... now I don't. It's as simple as that. Luke came out and not only took care of the pests, but also took the time to educate me on why I might be getting them and what I could do in the future to prevent them. I highly recommend Spot On for any pest control issues you might be having.
My experience with this company was nothing but good; they are highly professional and got to the job in a timely manner. The price for termite treatment was competitive, but for the service and professionalism, it was definitely on the low end. Thanks, spot on!
We’ve been using their services since we first moved into our house years ago. Zero issues over the years, great customer service and zero pests.
