As spring brings warmer weather and sunshine to the UK, it also delivers an unwanted consequence - smelly wheelie bins that draw hordes of flies as the plastic warms up. When temperatures reach 15°C, flies start laying eggs, and wheelie bins offer the perfect breeding environment with their warm, moist conditions ideal for maggot survival. Throughout spring, it's vital to keep a close eye on your bins, as food remnants seeping from rubbish bags create an attractive food source for these pests.
