Earwig Control

• Sightings at night: In kitchens, bathrooms, or damp utility areas
• Large numbers outdoors: Under garden furniture, pots, or in compost heaps near entry points
• Damage to houseplants: Irregular holes in leaves or petals, similar to slug damage
• Finding earwigs in bedding or laundry: Indicates significant indoor movement
• Presence after rain: Earwigs shelter indoors when the ground becomes waterlogged

Earwig control focuses on reducing harbouring conditions outdoors and treating entry points and indoor hotspots with residual insecticide.

• Step 1: Inspection. Identify entry points, harbourage areas, and conducive conditions
• Step 2: Perimeter treatment. Residual insecticide applied to the exterior wall base, around doors, windows, vents, and potential entry points
• Step 3: Indoor spot treatment. Targeted application in affected rooms, focusing on cracks, crevices, and skirting boards
• Step 4: Harbourage reduction advice. Practical recommendations to remove conditions attracting earwigs to the building

All products used are COSHH-compliant and applied by trained, insured technicians.

• Remove harbouring material: Clear garden debris, leaf piles, and compost heaps from the immediate building perimeter
• Move pots and furniture: Away from external walls
• Seal entry points: Fill cracks, fit draught excluders to doors, mesh over vents
• Reduce outdoor lighting at night: Light attracts earwigs and other insects to entry points
• Check plants: Before bringing them indoors, especially in late summer
• Reduce moisture: Fix leaking gutters or standing water near the building

We provide earwig control across Darlington, Stockton, and Hartlepool. Earwigs are often found alongside spiders and ants as occasional invaders. For hospitality venues and food businesses, perimeter treatment is an important part of an integrated pest management programme. See how we work for details of our approach.

Spring (March to May) - Emergence and breeding: Earwigs emerge from overwintering sites in soil, leaf litter, and garden debris. Females tend their eggs in small chambers in the soil, which is unusual behaviour for insects. Nymphs hatch and begin feeding on decaying plant matter, aphids, and other small invertebrates. Watch for: earwigs appearing under plant pots, stones, and garden furniture as temperatures rise; activity around compost heaps and mulched garden borders; and occasional earwigs found in ground-floor rooms near garden doors across Hartlepool, Darlington, and Durham.

Summer (June to August) - Outdoor populations peak: Earwig populations reach their highest numbers outdoors. They are active at night, feeding on plant material, aphids, and decaying matter. During the day they shelter in dark, damp crevices. Watch for: earwigs in cut flowers brought indoors, large numbers sheltering under patio furniture and pot saucers, earwigs attracted to outdoor lighting at night, and increasing sightings near external doors and air bricks. Hospitality venues with outdoor seating and food businesses across the region often see earwig complaints during this period.

Autumn (September to November) - Indoor migration: This is the peak period for indoor earwig complaints. As night temperatures drop, earwigs seek shelter inside buildings through gaps under doors, around pipework, through air bricks, and via cracks in external walls. Properties with gardens, particularly older homes in Stockton, Middlesbrough, and Sunderland, see the highest numbers. Watch for: earwigs in bathrooms, kitchens, and utility rooms at night; clusters behind skirting boards, in folded towels, and inside shoes left near exterior doors; and earwigs appearing in numbers that cause distress despite being harmless.

Winter (December to February) - Dormant period: Earwig activity drops sharply as they enter a dormant phase, sheltering in soil and under debris. Indoor sightings become rare. Watch for: any continued indoor activity which may indicate earwigs have established harbourage inside the building rather than entering from outside. Winter is the ideal time for prevention: clear leaf litter and debris from the building perimeter, seal gaps around external doors and pipes, fit mesh over air bricks, and reduce ground-level clutter along external walls.
