Property expert warns of unusually fierce moth season in late summer 2025 –
Derek Bruce, homes and property expert at SMSTS Course, cautions that peak moth season (late summer, August–September) is showing signs of being far worse than usual in 2025.
“Unlike typical years, we’ve had a milder winter followed by a warm, humid spring and summer which speeds up the entire moth life cycle—from eggs to adults—leading to quicker hatches and more generations”
Why Moths Are Thriving This Summer
- Longer active cycles: London’s warm, damp weather accelerates egg hatching and larval development—some eggs now hatch in as little as 4 days.
- A milder winter & early spring: Conditions that favour survival of eggs and larvae. Plus, a “second wave” is emerging this August after a big spring surge.
- Urban density: Flat-to-flat migration in densely built areas makes it easier for infestations to spread.
“This isn’t just normal moth season—it’s a full-scale moth boom,” warns Derek. “More generations mean more potential wardrobe and textile damage.”
Watch For These Signs
- Small holes and silk webbing on natural fibres (wool, silk, cashmere).
- Tiny beige or straw-coloured moths flying around wardrobes, walls, or skirting boards.
- Larvae casings or shed skins—look like grains of rice—in drawers, under furniture, or within folded clothes.
Rapid-Response Prevention Plan
| Action | Why It Helps |
| Deep-clean & vacuum weekly, esp. behind wardrobes, under furniture | Removes eggs and larvae gathered in undisturbed areas |
| Hot wash or freeze vulnerable items (50°C or –18°C for 72 hrs) | Kills larvae, eggs, and adult moths |
| Pheromone traps + natural repellents (cedar, lavender, rosemary) | Helps monitor and deter the adults |
| Store off-season garments airtight, using breathable bags for in-use clothes | Prevents moth infestation and reduces humidity |
| Inspect second‑hand or market goods before bringing them inside | Stops egg introduction |
What Makes 2025 Special
- Climate boost: A mild winter, early warm spring, and humid summer have created ideal breeding conditions.
- Faster, more frequent cycles: Reduced egg incubation time—down to a few days—means more infestation waves.
- Big spring spike spilling into summer: Early sightings in April–May are now compounded by a stronger late summer wave.
