There are always issues with occasional invaders within building but lets just focus on the Top 2 – Flies and Cockroaches
Flies – the first and foremost most important is the inspection, after you decide on which species it then can treated. Each pest we deal with has unique and often times complex life cycles which must be addressed. House flies are common in building but are usually an issue with door being left open, while Fruit flies are a result of ripening fruits or decaying organic matter. So lets look at a few:
House flies – is there animal waste or garbage outside which could bring this pest to your door? If this is a home its easy to reduce house flies by just removing or cleaning up animal waste. If this is a restaurant, just how close is the garbage or dumpster? Is the lid closed, this in itself could reduce flies and scavenging birds and animals.
Fruit flies – Drains are the biggest culprit, they need to be clean and screens should be in place. Just pouring bleach into a drain will never work, the scum collects on the sidewalls and just pouring bleach will only maybe touch the surface of the scum. Phorid flies prefer areas like cracks and crevices and are similar to Fruit flies in liking decaying organic matter. The product of choice should be a scum eater, like a bio agent. I love those products because they eat grease which often builds up in somewhat hidden areas. Don’t forget areas like mops or kitchen equipment.
Bottle or Flesh flies, if you encounter these it is often associated with dead rodents or decaying matter.
Cockroaches – both German and American can create some issues within restaurants. American or lots of people call them Sewer Roaches, usually associated with drains and grease traps. So keeping the place clean is essential. German Roaches are probably those ones that cause the most sleepness nights to owners, they can be brought in via boxes or materials and can quickly set up shop. Cleaniness is important but these roaches are experts at muliplying and taking advantage of every single opportunity. If you see one there are probably hundreds, just take my advice and call a Pro right away. You need the right tools and the knowledge and you need to get a handle on this ASAP.
Don’t forget it is about the inspection, followed up by detection and then treatment and prevention. (BASF flies Smartsolutions guide)
