Ants: Identifying ant trails & getting rid of them sustainably

Ants are beneficial creatures in the garden – but they can quickly become a nuisance in the house, on the patio, or in the kitchen. Typical signs are ant trails along edges, joints, or baseboards. Here you will learn how to identify ants reliably, why they come, and how to effectively and permanently reduce them.

What are ants?

Ants belong to the Formicidae family and live in colonies. They communicate via scent trails, which creates clearly visible "trails." In the house, ants are usually looking for food (sugary or protein-rich) and water. If the source is attractive, they will reliably keep coming back.

Colony-forming Follow scent trails Search for food & water

Important: Ants rarely disappear "on their own" if food and access exist. Sustainable control means addressing source + trails + entry points simultaneously.

How to identify an infestation

Ant trails along walls, joints, or baseboards
Ants near food supplies, trash, pet food, or fruit
Entry through small cracks (windows, door thresholds, cracks)
Outdoors: Activity in patio joints, pavement, garden bed edges

Green Guardia Tip: Observe where the trail leads: If you find the entry point and the "target," you will solve the problem much faster.

Where do ants frequently appear?

Kitchen (countertops, trash, pantry)
Patio/balcony (joints, planters, door areas)
Living areas (baseboards, socket areas, cracks)
Garden (paths, garden beds, lawn edges)

Why do ant problems occur?

Open food, crumbs, sugary liquids
Pet food (bowl/bag) as a permanent food source
Dry periods: Ants look for water in the house
Many entry points (joints, cracks, leaky areas)

What to do against ants? (natural & sensible)

1. Remove access to food & water

Thoroughly clean countertops, remove crumbs
Store food in airtight containers
Empty trash regularly, keep pet food clean

2. Remove scent trails

Wipe down walkways with a damp cloth (to make the trail "disappear")
Repeat several times – especially with high traffic

3. Seal entry points

Close joints, cracks, and gaps
Check door thresholds/window areas

Natural control & bait logic

If ants come into the house regularly, a lure bait can be useful, so that workers carry the food back to the nest and overall activity decreases. At the same time, the most important lever remains: reducing the cause (food, water, access).

Why the combination works: If you stop the trail and access while simultaneously reducing the attractiveness inside the house, ants will lose the reason to keep coming back.

FAQ about ants

Why do ants keep coming back?

Because the scent trail remains and there is an attractive source (e.g., sugar, crumbs, pet food). As long as access + reason exist, the trail remains active.

Should I just wipe away the ant trail?

Yes – but consistently. Wiping once is often not enough. It is also important to remove the source and find the entrance.

What is the best prevention?

Cleanliness, airtight storage, waste management, and sealing small cracks. Check regularly, especially in spring/summer.

Are ants bad in the garden?

In the garden, many ant species are beneficial. It usually only becomes problematic when they consistently find food near the house or settle under patios/slabs.
