Cockroach sightings can become common over winter and if they are appearing inside the home, immediate action is recommended to stop your home from being a nesting ground for these creepy crawlies. Because these critters are so resilient and can go up to a month without food, they can live inside or around the home for long periods of time. Find out more about the cockroach lifecycle and tips on how to combat them.
Understanding the cockroach life cycle can help you determine what is actually happening on your property, we also share some great tips for preventing cockroaches from co-habituating with you!
The cockroach life cycle is comprised of three developmental phases, the egg, nymph and the adult stage. Most cockroaches are oviparous — their young grow in eggs outside of the mother’s body. In these species, the mother roach carries her eggs around in a sac called an ootheca, which is attached to her abdomen. This sac contains anywhere between 6 and 40 eggs.
Depending on the species, the ootheca can either remain attached to the cockroach until the eggs are ready to hatch or deposited in a hidden place where the eggs will hatch. Other roaches are ovoviviparous. Rather than growing in an ootheca outside of the mother’s body, the roaches grow in an ootheca inside the mother’s body. Yikes!
After 6-8 weeks, immature cockroaches known as nymphs emerge from the case. They are mostly white in colour and will gain their brown colour as they age. These nymphs will feed and go through a series of moultings over a period of one year as they develop into adults. Food in the home and even pet food can sustain a cockroach. The adult cockroach can live 1-2 years.
FACT: A German cockroach and her young can produce 300,000 more cockroaches in one year which understandably can become a big problem.
3 Tips to Combat Cockroaches
1) Keep the home clean; kitchens are prime locations for cockroaches as they feast on leftover food and scrapes layout on the counter tops or in the pantry. Pet food can also be a target for the night time munchies.
2) Use Ecomist Sniper to create an invisible barrier for cockroaches who attempt to enter your property. Spray around doors especially front and back, along skirting boards and in the laundry room. Sniper is also great to use in the garage and on any outdoor furniture to deter cockroaches, spiders and other crawling insects.
3) Rubbish bins can attract cockroaches looking for winter snacks and an area to hide. Clean bins regularly and use an air tight cover to prevent access.
