Fly Killer Spray Buyer’s Guide

Insect sprays are a cost-effective way of immediately killing flies and other unwanted insects that invade your home, but which is the best fly killer spray?

Here are a few things to look out for.

Quick Action

No-one wants insects to suffer, so a quick death is preferable.

Use a good brand so the effect is instantaneous on close application and a few minutes when clearing a room.

Kills Lots of Bugs

Choose an insecticide that kills a range of bugs including the tiny ones that are so annoying – that’s the fruit flies and mosquitos that manage to avoid swatting and electric fly killers.

Bar the Entry

The best fly killer sprays can be used around the entrances to your home to stop insects coming in. This helps avoid spraying your home in the first place.

Conclusion

If wiping fly innards or electrocuting insects isn’t for you, then the best fly killer spray is an important purchase.

There are plenty on the market, so choose one best suited to your needs. My top recommendation is the best on the market but my other suggestions work well and are the best buys for your cash.
