It was so incredibly easy to book a visit through their website. They had great communication. I knew they were extremely busy the day they came to see me, but they were still pretty much bang on time. Without me asking too much, they explained very simply what they were doing, how it would work and what may happen if there was any follow up. Oh, and we had a great conversation. Very knowledgeable and fun to talk to. Would highly recommend.

Why get rid of Cockroaches?

These unwanted invaders aren’t just a disturbing sight in your home: they pose serious health and property risks that demand immediate attention. In Wellington, we commonly encounter three main species: German cockroaches, which infest kitchens and breed rapidly behind appliances, and more commonly, the Gisborne and native wood cockroaches, which typically live outdoors but venture inside during poor weather or mating seasons.

If sightings alone aren’t distressing enough, cockroaches are also notorious disease carriers, capable of spreading dangerous bacteria that cause diseases like diarrhoea, dysentery, and salmonella. Their droppings and shed skins can trigger asthma and allergies, particularly in children. Beyond health concerns, these pests can cause significant property damage by contaminating food, leaving unsightly droppings that stain surfaces, and creating unpleasant odours that can permeate your home.

While DIY cockroach treatments might seem like a cheap option, they often fail to address the root cause and can worsen the problem by scattering the cockroaches to new areas of your home. Professional cockroach pest control targets breeding grounds and uses commercial-grade treatments that eliminate current infestations and prevent future ones, making it the most cost-effective solution.

What makes cockroaches particularly challenging is their incredible breeding rate. A single German cockroach can produce up to 40 eggs every few weeks; infestations can explode rapidly.

FAQ – How do you treat cockroaches?

There are three main types of cockroaches we deal with here in Wellington. The two most common are Gisborne and native wood cockroaches. These guys live outside harbouring in gaps and crevices. Often, they will wander around inside to escape poor weather, or looking for a mate or suitable place to plant their ootheca/egg cases. When dealing with Gisborne and wood cockroaches we dust treat all gaps and crevices around the outside of the house, focusing on decking, fences, and gates close to the house

The third type are German cockroaches. These can be found infesting kitchens, living in breeding grounds behind appliances and in dark corners and crevices. To control German cockroaches, we need to hunt out their breeding grounds and apply baits and sprays in and around these areas.

“Highly knowledgeable, explained how the products he used worked”

Amazing service! We inherited cockroaches after buying a second hand fridge. Nic is highly knowledgeable, explained how the products he used worked and that they were in no way toxic to my family. He arrived on time, was friendly, explained the process and even removed his boots at the door(trust me most contractors don’t!) Highly recommend A+++++

Cockroach Control FAQs

A full treatment information sheet is supplied with every appointment confirmation. Though we dream of treating empty houses without furniture, people, or pets; that is not the reality of residential pest control. So, below is a guide, not a rule book. We will always work with you to make practical arrangements, for a successful and stress-free pest service fully backed by our solid guarantees, with no charge for returns.

Answer: Clear clotheslines, close all windows and doors, and remove items blocking access to outside walls and internal skirting boards (interior treatments only).

  • Important: Please stop using supermarket cockroach sprays, bug bombs, or DIY foggers. These harsh chemicals scatter breeding colonies deeper into wall cavities and build up their resistance to treatment, making it harder for our professional treatments to do their job.
  • Your Invader: For Gisborne or Native Wood cockroaches, we focus primarily on a thorough exterior treatment. For German cockroaches nesting inside kitchens, an internal treatment is essential.
  • Exterior Prep: Bring in all washing from the line, close all windows and doors tightly, and clear any stored items blocking our access to your home’s outside walls, decking, or fence lines. We will easily work around or shift large furniture; often it requires treatment too.
  • Interior Prep: If you are booked for an interior service, clear items away from your skirting boards and window sills. Place all fruit bowls, pet bowls, and open food packages inside closed cupboards.
  • House Washing: Complete any planned external house washing *before* our team arrives so you do not accidentally wash away our protective residual barrier.

Answer: Full interior repellent sprays require vacating the home for 3 hours. Targeted German cockroach kitchen treatments and exterior applications only require you to avoid the specific treated areas for 1 hour until dry.

  • Full Interior Vacate Window: Full interior repellent sprays require all family members and pets to vacate the home for 3 hours to allow the product to dry completely.
  • German Cockroach & Exterior Only: For targeted German cockroach kitchen treatments or standard exterior services, you can remain safely on-site but must stay completely clear of the treated areas for 1 hour until the application dries.
  • Strategic Baiting: In kitchens, we use targeted powder and gel baits. These baits are placed in hidden, non-accessible crevices, often behind appliances, or up high where curious children and pets cannot reach them.
  • Eco-Friendly Targeting: Our safety-first approach focuses heavily on hunting out exact breeding hotspots. This ensures we destroy the targeted pest without harming non-pest species like bees and butterflies.

Answer: Expect an immediate drop-off in activity as existing cockroaches are eliminated on contact, with full colony destruction achieved over the following weeks.

  • Outside Species (Gisborne & Wood): You will quickly notice a massive population collapse. These species breed outside, and our targeted dust treatments in gaps, fences, and gates stop them from wandering indoors to escape bad weather.
  • Inside Species (German): You will see foraging cockroaches rapidly decrease as they take our slow-acting gel baits back to the breeding grounds behind appliances, wiping out the source population.
  • Debris Cleanup: Our team will safely remove and dispose of any old, ineffective baits or accessible cockroach bodies found inside during your service.

Answer: Contact us immediately if you observe persistent cockroach activity inside your kitchen or main living spaces after treatment.

  • 6-Month Guarantee: Our professional cockroach treatments are fully backed by a solid 6-month warranty to keep your home protected and give you peace of mind.
  • Free Service Returns: If target activity has not completely ceased within your initial post-treatment window, our team will return to re-treat at zero extra charge.

Answer: Eliminate external organic matter, seal internal structural gaps, and check second-hand appliances carefully before bringing them inside.

  • Stop Hitchhikers: German cockroaches are rarely accidental wanderers—they are usually introduced. Always thoroughly inspect second-hand fridges, microwaves, or boxes before bringing them into your home.
  • Yard Management: Gisborne and Wood cockroaches love damp organic matter. Keep mulch, firewood piles, and bark gardens clear of your home’s immediate foundation walls to reduce their outdoor harbourage zones.
  • Proactive Maintenance: Because resilient outdoor populations can migrate from neighbouring properties over time, we recommend regular, preventative exterior barriers to keep them out permanently.

How to be free of Cockroaches

Prevention is your best defence against future cockroach infestations. These resilient pests thrive in environments that provide food, water, and shelter, so eliminating these attractants is crucial for cockroach control and maintaining a pest-free home.

Start by addressing potential nesting sites and food sources:

  • Store food in airtight containers and clean up crumbs immediately
  • Keep pet food sealed, and don’t leave it out overnight
  • Regularly clean behind and under appliances, especially in the kitchen
  • Remove cardboard boxes and clutter that provide hiding spots
  • Keep outdoor bins sealed and away from your house

Even with the most thorough prevention measures, you might occasionally spot a cockroach, especially during wet weather when outdoor species seek shelter. If you notice any signs of cockroach activity like droppings, egg cases, or live insects, don’t wait for the problem to escalate. Just seeing one or two cockroaches can indicate a larger infestation hiding in your walls or under appliances.

Regular inspections can catch potential problems before they develop into full-blown infestations. Consider scheduling maintenance treatments every 6-12 months to maintain a protective barrier around your home, especially if you’ve had problems in the past.
