Why Bother with Spider Control?

  • Messy webs around the house
  • Danger to your children and pets
  • Potential life-long consequences from spider bites

Spiders are possibly one of the most feared and disliked creatures in New Zealand. It's easy to get dramatic about the reasons for spider control yet contrary to the common opinion they are not all dangerous nor are they unattractive. Some varieties of spiders can have a serious impact on your home and family - spider control methods can help remove these.

  • Some species of spiders, pose a threat to the lives of family and pets.  If dangerous spiders are found in your living environment around the home, some form of spider control should be implemented.
  • Even though spider control treatments are not permanent, they will break the life cycle of the spiders effected, meaning it will take a lot longer for these problems to appear again.

Spider Control Methods

Spider control is always a challenge.  Spiders are a beneficial part of our eco-system and help to keep other insect populations under control, so balance needs to be achieved while attempting to achieve spider control in the targeted area.

Spider control methods and strategies should also be targeted to the spider's type. Spiders can be divided into two main groups:

  • Crawling or Hunting spiders; and
  • Webbing Spiders

Webbing Spiders

Webbing spiders rely on silk for movement and spinning webs to catch their prey.
Unless the species is considered dangerous, the best method of spider control is to move them back into their natural habitat. The DIY system known worldwide involves a fearless member of the household, a glass or bowl and paper/cardboard slid underneath - followed by a release back into the wild!

A method used for webbing spiders is:

  • Reducing The Food supply: Reduce the food supply for webbing spiders by turning lights off at night, and implementing other pest control measures (such as mosquito control, fly control, etc).  
  • Removing webs: Removing spider webs may stop you from inadvertently walking into them, but this is not a long term solution. 
  • Using Chemical sprays: You can spray a spider directly with insect spray as a case-by-case form of spider control.
  • Spraying chemical on the webs is not always effective since most webbing spiders hang on using claw-like structures on their legs which do not absorb chemical residues.

Though it doesn't usually help to cut down spider populations, it is always advisable to remove the web immediately after the treatment.  This allows you to determine when the spider population is building again and when further spider control is needed.

How long does spider control work for?

Residual spider control treatments work with the environment being its control, if the area sprayed is subject to the elements then it will not last as long as a sprayed area that is sheltered. The spider population will build up again over time.  If you have a lot of bush and foliage in the immediate vicinity of your property, the time between treatments will be much shorter.

fly control methods

Our treatment targets Flies & Spiders

Flies are considered pests for several reasons. One of the main reasons is due to their flying habits which can cause annoyance to humans. This is not only annoying but can also be viewed as unhygienic and cause embarrassment for food processing establishments such as cafes and restaurants.
Flies also pose a significant threat to public health with their ability to transmit diseases such as Salmonella, dysentery, hepatitis, typhoid fever and other internal parasites. As a result, fly control is extremely important especially in food processing establishments.

I have a fly problem - What can I do?

Effective fly control usually involves an integrated approach of both chemical and non-chemical control methods. Improved hygiene and sanitation is the most important factor. The quick and efficient removal of garbage and waste products will reduce fly numbers by reducing attractants and breeding sites.

  1. Regular treatment is the way to keep flies away.
  2. Hygiene.
  3. Sanitation.

All the above help to eliminate flies.
