A BETTER CLEAN
What type of cockroach are you wanting us to treat?
Is it the Gisborne, the German or just our Native Black Cockroach?
This is actually quite important as it can determine which of several methods we would advise to treat them.
The main cockroach we tend to come across is the German Cockroach which is the one that carries diseases and often causes food poisoning.
This cockroach is 13-16mm long, light brown, with wings (although it doesn't fly) and the female often has an egg capsule (uthecae) hanging out her rear end. It’s usually found in kitchens.
The Native Cockroach and the Gisborne Cockroach are both wingless.
These two aren’t usually anywhere near the pest the German Cockroach is. They have lines running across their bodies like slaters (or wood lice).
The Gisborne Cockroach is about 20-30mm long and often has a yellowish or clear stripe down either side of its body.
The Native Black Cockroach is about 20mm long.
We have a few different treatments to treat cockroaches. Some are more thorough which we would recommend for German Cockroaches and others would be regarded as maintenance treatments or Native Cockroach treatments.
This takes a lot of work on your behalf before we arrive.
You need to empty every cupboard and drawer in your kitchen and pantry. This includes the pot cupboard and the cutlery drawer.
The best place to put all the contents is usually both on and under the dining table and throw a sheet over the top of it.
Some items must stay in the kitchen to be treated though. They are electrical items like cake mixers, coffee makers and microwaves where we often find cockroaches. We have even found them in modems.
All the drawers and cupboards should then be washed before treatment as you don’t want to be washing these afterwards or you’ll remove the treatment.
You need to empty the laundry and bathroom cupboards, the hallway and hot water cupboards, all the wardrobes (throw everything onto the beds).
Then pull all the furniture in the house out from the walls so that we can treat all the ceilings, the walls, the skirtings, every nook and cranny we can find and every where in the kitchen.
We sometimes have to drill small holes out of sight in the toe kicks under the kitchen cupboards so we can pump dry insecticide into the areas there where sprays can’t reach. We also pump dry insecticide into electrical items like the fridge compressor and the back of the stove and so on.
If you’ve seen them coming out of holes or cracks in the walls, the removal of power points or light fittings may be necessary in order to treat inside the walls. This costs extra. Likewise when sometimes there are cockroaches in places where sprays and powders can’t be used, like in books or computers.
What we can do in these situations is to have all these items placed in large plastic rubbish sacks and fill them up with insect gas. Leave them for a day or two in the bags and that’ll kill any insects in there... Or we can apply Gel Bait on or near these items.
There’s to be no pets or people inside for about 4 hours and the house needs to be well ventilated before re-entry.
When you come back inside you will have the job of vacuuming up dead cockroaches, putting everything back into place, and cleaning the food preparation benches before any uncovered food is placed directly onto them.
Don’t wash down any areas that won’t have uncovered food placed on them. That would clean off the treatment which will usually continue to work for several weeks.
That is really important because the treatment doesn’t kill the eggs, so when the eggs hatch you will want the baby cockroaches to walk on a treated surface and get killed.
This is a very thorough treatment which usually shows immediate results.
Please note that there may be a solvent odour from this treatment that will dissipate over time.
Cost is $380.00 around town.
Extras would be:
$35 per light fitting or power point you wanted removed for treatment in wall cavity …
and $25 per item needing Gel Bait treatment.
Insect gas treatment is usually between $150 - $200.
Average 3 bedroom house =(9 rooms - LD = 3, 3 Br = 3, H & Laundry = 1, K = 1, T & B = 1)
Average room is 12m2
SEMI - THOROUGH
We could do a real thorough treatment like I’ve just mentioned but only in the kitchen and dining areas.
This can really knock the cockroaches around but there is a possible drawback.
As the cockroaches run away from the treated area they are very likely to drop their egg sacks in other parts of the house and so start an infestation elsewhere.
If you wanted us to treat just the kitchen/dining areas you would have to take the risk of them spreading, yourself.
This treatment costs $250.
NO HASSLE SPRAY TREATMENT
This treatment is usually used for Native Black Cockroaches and for Gisborne Cockroaches that haven’t taken over the kitchen.
You don’t have to empty any cupboards or move all the furniture.
We will spray treat all the ceilings, walls and skirtings that are accessible without moving furniture around.
We don’t treat inside the kitchen cupboards and drawers with this treatment.
This would kill most insects crawling over it for at least 12 weeks under normal conditions.
This treatment costs $130.00 for inside the house.
Note: Many people want us to treat areas outside the house for these Cockroaches as they are often found in wood piles, tool sheds, under balconies and so on. In these cases we charge extra.
NO-SPRAY GEL TREATMENT
Gel treatment involves no hassle for you. You won’t have to empty any cupboards and drawers and you don’t have to move all the furniture. You don’t have to get out of the house when we do this treatment.
We even treat restaurant kitchens with Gel while the staff are still working in them.
Gel treatment kills every cockroach that eats it, every cockroach that eats a poisoned cockroach (they’re cannibals you know) and because they are such dirty creatures that they eat each others faeces, every poisoned faeces that gets eaten will kill the cockroach that eats it.
Gel bait lasts for up to a year or until it is all consumed.
Gel treatment has proven to be very effective on it’s own and has often wiped out cockroach infestations with just one treatment. But this is not always the case. Quite often they need to be treated again after a month.
This treatment costs $185 per treatment so if you get away with a single treatment it’s more economical than the more thorough treatment. But if you happen to need a repeat treatment then it would cost a bit more.
GENERAL INFO ON COCKROACHES
The German Cockroach is the most common pest cockroach in N.Z.
The females may be seen with a light-tan egg capsule protruding from the abdomen. One female may produce between four and eight capsules with 30 to 50 eggs in each.
These insects can spread disease organisms and illnesses such as gastro-enteritis, dysentery, diarrhoea, and food poisoning.
They carry disease organisms on their legs and deposit them while they are moving and feeding.
Cockroaches generally hide in areas close to moisture and food.
As long as the interior of a building has warmth, moisture, minute food fragments, and hiding places such as tiny cracks, there is a chance of cockroach infestation.
Corrugated cardboard (most cardboard boxes) for example, provides enough space for cockroaches.
Cockroaches are generally nocturnal. If you see stray cockroaches during the day, it suggests that the population is high and that hiding places are overcrowded.
Food sources for cockroaches are more widespread than most people realise.
Most species are scavengers, eating starchy materials, sweet substances, and meat based products.
They also eat such materials as cheese, leather, bakery products, starch in book bindings, glues, hair, dead animals, and plant remains.
Wastes such as beer spillage are also attractive to them.
Crumbs of food in a work-desk drawer are enough to feed these pests.
Fragments of ice-cream and drops of cordial in theatres are all that is needed to feed a population, especially as it is likely to be added to each day.
Moisture is even more essential to cockroaches than food.
Sinks and wash-up areas provide them with water, so kitchens are invariably a focus of infestation.
Bathrooms and laundries are other likely areas, although they have been found in bedroom drawers, where they can feed on materials such as organic-based glues.
If a complete service is to be performed, all parts of a house may have to be examined and treated.
In order to reduce the risk of cockroach infestation we advise clients to carry out the following steps:
1. Remove all food residues
2. Eliminate "dead" spaces where any form of organic matter may accumulate
3. Inspect incoming goods, including their containers etc.
4. Rotate stock systematically so that no packages remain long enough to become infested
5. Develop high standards of hygiene
6. Wash down all food preparation surfaces after use
7. Allow insecticide 7-14 days for complete effect although your treatment will often continue to control insects for several weeks
8. Clean up and destroy any egg capsules you may find to prevent reinfestation.
