Q: Will bleach kill drain flies?

• <div><p>Bleach can technically kill drain flies, but it&rsquo;s not really a great tool for getting rid of an infestation. Bleach flows down your pipes too quickly to penetrate the film where drain flies lay their eggs. Alternatively, you can use it to clean around drains, which can help prevent drain flies from returning once you get rid of the infestation.</p></div>

Q: Why am I finding mouse droppings but not seeing any mice?

• <div><p>Finding mouse droppings without seeing any mice is a common sign of an infestation because mice are nocturnal and skilled at hiding from humans. Droppings are often the first and most visible evidence of their presence. The location, quantity, and freshness of the droppings can help you determine where the mice are most active and how severe the infestation might be. Since mice are active at night and often travel through hidden pathways like inside walls, you may not see them directly. It's important to look for other signs of an infestation, such as gnaw marks, scratching sounds, or greasy trails along walls. If you find droppings, consider setting traps or contacting a professional exterminator to address the issue.</p></div>

Q: What methods are used by pros for termite control?

• <div><p>Chemical treatments, bait systems, and physical barriers are common approaches.</p></div>
