How to Identify German Cockroaches
When fully grown, adult German cockroaches are a flat, tan brown insect, with the distinguishing feature of two dark side-by-side lines that start at the back of their head. Though they don’t actually fly, German cockroaches still have two developed wings. Size-wise, German cockroaches can be more than a centimetre long. Female German cockroaches can reproduce rapidly, producing 40 eggs at a time, and with up to 7 sets of offspring throughout their lifetime. Baby German cockroach nymphs look fairly similar to adults, though they are smaller, darker, and don’t have wings.Signs of German Cockroaches
Maybe you suspect you have a German cockroach infestation, but you don’t know if you’ve seen any in your \Sydney home. Other signs of German cockroaches include little pepper or coffee ground-like dropping marks around your home. You may also spot oval-shaped egg cases, smell a strong, musty odour, or see dead cockroaches outright.What Attracts German Cockroaches
Like other cockroach species, German cockroaches want a nice place to live – somewhere warm, moist, and with plenty of food to eat. These scavengers love to eat anything, from glue to pet excrement, pet food, soap, and meat scraps.Where to Find German Cockroaches
All cockroaches like dark, quiet places. However, with their unique, wide, flat shape, German cockroaches are more easily able to move in and out of tiny places, like the cracks and crevices around your home. German cockroaches also like warm spots, like TVs, computers, and other electronics, and under your sink, dishwasher, stove, or refrigerator. You may even find them in your walls or ceiling pipes.How to Prevent German Cockroaches
Pest infestations can happen in even the most pristine North Shore homes. However, since German cockroaches love heat and moisture so much, be sure to keep an eye on your pipes, drains, and sinks, and repair leaky pipes promptly. Clear up leftovers and scraps quickly, too, with pet food stored in an airtight container. Remember to wipe up crumbs, food scraps, and spills in the kitchen and the garden right away. Even dirty dishes can be attractive to roaches. Vacuum up food crumbs, tiny egg cases, and other debris regularly. Another prevention tip is to seal all points of entry, like cracks, crevices, and other tiny cockroach-friendly openings in your home.How to Exterminate German Cockroaches
Wondering how to exterminate German cockroaches in your Northern Beaches home when you already have an infestation? One of the best options is to use an insect killer spray. Use these sprays only on non-food and non-porous surfaces; however, be careful using insect sprays in your kitchen. The only effective insect sprays against German roaches are non-repellent varieties because German cockroaches are able to detect repellent insecticides. So, use non-repellent sprays for the best chance of a working solution. You can also use roach baits. Roach bait involves the cockroaches bringing the insecticide bait back to other cockroaches, killing all the cockroaches on your property. If you choose this option, gel baits are a faster option than bait stations. However, bait stations are still a good option for ongoing maintenance after using gel bait. But, bait may seem attractive to children and pets, so be careful. But the best way to keep your Sydney home cockroach and pest-free is to book regular pest inspections from a licensed inspector like Everest. Before you begin any work with a pest inspector, you should check that the technician has a valid termite inspection license.
