During colder months, most Bristol homeowners expect a break from insect activity. Yet for many living in Redland, ants can still make unwelcome appearances — particularly in kitchens and warm indoor spaces. Understanding why this happens and how to respond can help you keep your home free from unwanted trails this winter.
Why Ants Appear Indoors During Winter
Ants are usually associated with warmer weather, but they don’t completely disappear in winter. Instead, they slow down and shelter in warm, dry areas — and heated Redland homes provide the perfect environment. Once inside, ants will search for food sources such as crumbs, sticky residues, and pet food, creating trails that can quickly spread throughout the kitchen.
Even small cracks or gaps around windows, doorframes, or skirting boards can allow entry. Once a few scout ants find warmth and food, they’ll leave pheromone trails for the rest of the colony to follow, resulting in sudden indoor infestations.
How Heating Systems and Food Attract Ants
Central heating keeps Bristol homes cosy but also confuses ants’ natural cycles, encouraging activity even during winter. Kitchens, in particular, are prime targets — the combination of warmth, moisture, and accessible food encourages ants to stay active indoors rather than returning to their outdoor nests.
Regular cleaning helps, but hidden food debris, dripping taps, or poorly sealed bins can still attract them. Once they establish a scent trail, ants can repeatedly return to the same location, making prevention and treatment vital.
Practical Tips to Prevent Winter Ant Problems
- Seal potential entry points: Use silicone sealant around window frames, skirting boards, and pipework.
- Keep kitchens spotless: Wipe surfaces daily, store food in airtight containers, and clean under appliances where crumbs gather.
- Fix leaks: Damp areas are ideal for ants and other pests; repairing small leaks can deter them.
- Empty bins regularly: Keep lids tightly sealed and ensure outdoor bins are clean.
- Disrupt scent trails: Wipe down surfaces with vinegar or mild detergent to break pheromone paths.
If the issue persists despite your efforts, professional treatment may be required to fully locate and remove the colony.
When to Call a Professional Pest Controller
If you notice repeated trails, ants appearing from under flooring, or activity near electrical outlets or skirting, it’s likely the colony has nested indoors. A professional pest controller can identify the source, use safe and targeted treatments, and advise on proofing to prevent re-infestation.

FAQs
Why do I still see ants in my Redland kitchen during winter?
Even in winter, ants can find their way into homes looking for warmth and food. In Redland, the combination of heated kitchens, indoor lighting, and accessible crumbs or pet food can trick ants into thinking it’s safe to stay active. What starts as a few scouts can quickly turn into visible trails if they discover a reliable food source.
Can I handle an ant problem myself or do I need pest control?
For very small infestations, thorough cleaning, sealing entry points, and disrupting ant trails with vinegar or detergent can sometimes work. However, if you’re seeing repeated trails, ants emerging from cracks or skirting boards, or activity around food storage, it usually indicates a hidden nest. In these cases, calling local pest control in Redland is the safest way to fully eliminate the colony and prevent future problems.
How quickly can a pest control technician deal with an ant infestation?
Professional pest controllers can often address visible ant activity on the same day, identifying where ants are entering and treating the colony effectively. They also provide ongoing advice to prevent re-entry — for example, proofing gaps, managing moisture, and maintaining clean food storage areas. Unlike DIY methods, professional treatment targets the root cause rather than just the visible ants.
What’s the best way to stop ants coming back in spring?
Spring is when ants become most active again, so preparation is key. Make sure all cracks, gaps, and pipework are sealed, maintain airtight food storage, and keep kitchen surfaces and floors clean. Some homeowners benefit from a winter inspection from a local pest control team to identify dormant colonies or potential entry points, which can prevent infestations before the weather warms up.
