Kiwis turn to Mortein for bug protection

It’s estimated there are more than 10 quintillion (yes, that’s a number!) insects in the world. But for some people, the sight of just one creepy-crawly sends us running to the hills.

Although insects are important for a functioning eco-system, most of us do not welcome them in our homes – and for good reason. Some insects can damage property, while others can carry disease. As you read this, cockroaches could be scurrying around your pantry or cupboard… Even if you’re not afraid of bugs, you probably don’t want them in your home unabated.

Fortunately, 84% of New Zealanders agree that insecticides generally work well, our survey found. Around one in three households even take the extra step in protecting their property by using insect sprays pre-emptively to stop pests before they become a problem. Interestingly though, 20% of us feel guilty about killing insects, particularly woman and young Kiwis.

But as the weather warms up, household insects are becoming more active, so you need to make sure you’re prepared to protect your home as best you can, and that’s where Canstar Blue can help. We’ve surveyed New Zealanders just like you from across the country to get their reviews of the insect spray they most recently bought, to help you decide which is best for fighting bugs. For 2015, we are able to report that Mortein has received our Most Satisfied Customers Award for insect spray.

What insects do Kiwis find most frightening?

We asked Kiwis what pests they are most frightened of. Although 37% claimed they’re not afraid of any creepy-crawlies, spiders and cockroaches topped the rankings:

  • Spiders 40%
  • Cockroaches 39%
  • Ants 7%
  • Moths 9%
  • Other 6%
  • None 37%

Interestingly, we found that younger Kiwis are more afraid of insects than their parents or grandparents. 58% of respondents under 30 years of age admitted to being afraid of spiders, compared to only 35% of those aged 50 to 59.

What do we want from insect spray?

From our survey, the drivers of satisfaction for insect spray were as follows:

  • Effectiveness 54%
  • Value for money 23%
  • Smell of product 14%
  • Packaging appeal 9%

Our results show that most Kiwis want an insecticide that lives us to expectations and successfully fulfills its promise. When we spray a pest, we want to make sure it doesn’t get away to bother us another day, even if this means paying a little extra for the peace of mind.

Understandably, 68% of respondents don’t like the smell of insecticides. So what’s the best alternative? Well, according to our survey, 40% of people say the next best way to deal with a pest is a good old fashion newspaper or magazine, followed by a fly swat (33%), then a shoe (25%).

What is in insect sprays?

Most conventional insecticides use a number of different neural-toxin agents to shut down an insect’s nervous system, thus killing them. The agents used by insecticide brands will usually differ depending on their spray’s intended purpose. For example, Mortein “Insect seeking fly spray” uses small amounts of allethrin andresmethrin, while some Raid cockroach sprays contain tetramethrin, cypermethrin and improthrin. Most insect sprays will not disclose its full list of ingredients, though it will tell you the key agents. This is normally found on the front, toward the bottom of the packaging.

The chemicals in insect sprays are generally harmless to humans in low or infrequent doses, though it is advised to avoid spraying insecticides around small children or animals. Before using any insect spray, make sure you have read and understood the directions and safety warnings printed on all insecticide packaging.
