Who This Is For

Written for business owners, landlords and anyone else in Des Moines who's dealing with ants or wants to keep them out.

The Problem

Most ants are a nuisance, but carpenter ants in Des Moines can weaken window sills, decks and roof framing over time by hollowing out damp wood. Fire ants, where present, sting. Pharaoh ants in a Des Moines home can even spread bacteria across food surfaces. Fire ant stings produce a burning welt that develops into a white pustule within a day or so.

Warning Signs

  • •Ants clustered around the dishwasher or under the sink.
  • •Tiny yellowish ants near bathroom fixtures.
  • •Ants trailing up exterior walls to the roofline.
  • •A rotten-coconut smell when ants are crushed.
  • •Ants in the pantry despite cleaning.
  • •Steady lines of ants along baseboards or counter edges.

Risks of Waiting

  • ⚠Ants spreading to neighboring units in multifamily buildings.
  • ⚠Rising costs as a small trail becomes multiple nests.
  • ⚠Contaminated food and prep surfaces.
  • ⚠Painful fire ant stings, sometimes with allergic reactions.

Treatment Options

Inspection and Species Identification

Typical published range: $75–$200

45–90 minutesBest: Every job; the species decides the method

Carpenter Ant Nest Treatment

Typical published range: $250–$600

Small drilled holes let a pro inject dust or foam into wall voids, sills and window frames where carpenter ants have settled in Des Moines homes. The moisture problem that invited them needs fixing too.

1–3 hoursBest: Carpenter ants nesting in damp or hollow wood

Sealing Gaps, Cleanup and Follow-Up

Typical published range: $100–$300 per visit

Sealing gaps won't replace baiting, but in Des Moines it helps the results last past this season. Ants find gaps thinner than a credit card.

30–60 minutesBest: Sealing gaps and confirming the colony is gone

Gel and Granular Baiting for the Colony

Typical published range: $150–$400

Foragers carry slow-acting bait back to the queen and brood. In Des Moines homes, a pro places gel in cracks along active trails and granules outdoors near nest sites.

Read the video transcript

Follow visible ant trails to the gaps where they get in, and take a photo before you clean or seal. Coarse sawdust near wood can be a sign of carpenter ants, so take a closer look. Cut back on open food and fix leaks, and check around plumbing and wall openings instead of only spraying the surface. Outside, check mulch, plants, siding and utility entries. The right treatment depends on what you find.

Frequently Asked Questions

How do I get rid of ants in the kitchen fast?
Tonight, wipe the trail and seal away the food. For a lasting fix in Des Moines, place gel bait along the trail, leave it alone for several days and seal the entry point once the traffic stops. Fast and permanent are different goals.
Is a quarterly ant control plan worth it?
Heavy landscaping, slab construction and Argentine or odorous house ants around Des Moines make recurring invasions likely, and a seasonal non-repellent band keeps most trails from ever reaching the kitchen. Light pressure in Des Moines is better handled visit by visit. It depends on pressure.
Why are ants in my bathroom when there is no food?
Trails under the vanity usually point to a leak. Fixing the drip matters as much as any bait a Des Moines technician places, so mention it when you book. Bathrooms in Des Moines homes supply the one thing ants cannot skip: water.
What is the difference between carpenter ants and termites?
Ants have narrow waists; termites resemble pale rice grains. If you are unsure, a Des Moines pro can identify a sample and tell you which problem you have. Carpenter ants are larger, faster and visible at night, while termites stay hidden inside wood in Des Moines homes.
Can ants damage my house?
That is uncommon but real. Carpenter ant wood damage is the main structural risk Des Moines pros look for on an inspection. Beyond wood, ants occasionally nest in outlets, junction boxes and air conditioner contacts in Des Moines homes, which can short equipment.
What time of year are ants worst?
Around Des Moines, ants are most active in spring and summer, when the colony is growing and workers are foraging. Around Des Moines, rain or drought can also push them indoors looking for food and water, so a sudden indoor trail is often tied to the weather.
Does DIY pest control actually work?
Around Des Moines, store sprays kill the ants you see but rarely the colony, so DIY results are usually temporary. Around Des Moines, bait is the more effective DIY option because workers carry it back to the nest, but persistent or structural ant problems are usually worth a professional.
