| September marks an important change in the pest control calendar. We may still get plenty of warm, sunny days, but shorter daylight hours and cooler nights are already beginning to influence pest behaviour. For homeowners and businesses, this makes September a particularly good month to think about both pest control and prevention. Some summer pests are still very much with us, while others are beginning to search for the sheltered places they’ll use during autumn and winter. This month, there are four pests we’d particularly recommend keeping an eye on: cluster flies, rats, mice and wasps. Autumn Cluster Flies If you’ve ever suddenly discovered large numbers of slow-moving flies around windows, lofts or upstairs rooms during autumn, there’s a good chance you’ve encountered cluster flies. Unlike houseflies, cluster flies aren’t generally attracted to food or poor hygiene. Their behaviour is seasonal. As temperatures begin to fall, adult cluster flies look for dry, sheltered places where they can spend the winter. Unfortunately, lofts, roof spaces, window frames and wall cavities provide exactly what they’re looking for. During September, you may begin noticing flies gathering on warm, sunny exterior walls before finding small gaps through which they can enter the building. Once inside, large numbers can congregate together in hidden areas. Signs of Cluster Flies to Look Out For You may notice: – Groups of flies gathering around windows – Flies appearing in upstairs rooms – Large numbers around loft spaces – Slow-moving or seemingly lethargic flies – Flies gathering on sunny elevations of a building One of the difficulties with cluster flies is that the problem can return year after year if a property provides a suitable overwintering location. If you’ve experienced cluster flies previously, September is a particularly useful time to take action before large numbers establish themselves inside the property. Rats: Now is the Time to Check Your Property Rats don’t suddenly appear when winter arrives. They’re active throughout the year. However, autumn brings an important change in their behaviour. As natural food becomes less abundant and temperatures start falling, rats increasingly look towards buildings for reliable sources of food, water and shelter. September therefore gives you an opportunity to identify vulnerabilities before rodent pressure increases further. Walk around the outside of your property and look for: – Gaps around pipes and services – Damaged air bricks or vents – Poorly fitting doors – Burrows near buildings, sheds or bins – Signs of activity around drains – Accessible food waste – Overgrown vegetation close to buildings Remember, the rat you see isn’t necessarily the biggest problem. Finding how it got there is just as important as dealing with the rat itself. Our approach isn’t simply about treating the immediate infestation. We can investigate potential access points and recommend appropriate proofing measures to reduce the chances of rats returning. Where rats are accessing a property through the drainage system, specialist solutions such as a Ratflap may also be appropriate. Mice: Small Gaps Can Become Big Problems Mice present a similar challenge at this time of year. Their small size means they can exploit surprisingly small gaps around buildings, and once inside they can find everything they need to establish themselves, warmth, nesting material, food and protection from the weather. Homes aren’t the only properties at risk. Warehouses, offices, schools, hospitality businesses, food premises, farms and industrial units can all provide excellent environments for mice. Signs can include droppings, gnaw marks, damaged packaging, scratching noises and shredded material being used for nesting. For commercial properties in particular, don’t wait for someone to spot a mouse before taking action. September is an ideal time to review proofing, monitoring and pest management arrangements ahead of the colder months. Wasps Haven’t Finished Yet It might be September, but don’t put wasp season behind you just yet. Established nests can still be very active at this point in the year. In fact, you may find wasps become more noticeable and persistent around food and drinks as the season progresses. They’re particularly likely to cause problems around: – Outdoor dining areas – Pub gardens – Cafés and restaurants – Bins and waste areas – Children’s play areas – Gardens and patios You may also still notice regular wasp traffic around rooflines, sheds, wall cavities or other nest locations. If you see the occasional wasp outside, there’s usually no reason for concern. However, persistent numbers of wasps travelling to and from the same location can indicate an active nest. Don’t block the entrance or attempt to disturb the nest. Contact a professional pest controller who can assess the situation safely. September is the Month to Think Ahead One of the most useful things you can do this month is look at your property from a pest’s perspective. Where could a mouse squeeze through? Is there a gap around a pipe? Could rats access waste or food? Are there gaps around the roofline where cluster flies could enter? Have you noticed wasps repeatedly disappearing into the same part of the building? Fixing seemingly small vulnerabilities now can help prevent much bigger problems as we move into autumn and winter. For businesses, this is also a good opportunity to review your pest management arrangements. Regular monitoring and preventative pest control can identify signs of activity before they become an infestation, helping protect your premises, stock, employees and customers.
