Why Green Shield Pest Control is better...

Green Shield is better than other forms of pest control, because it works, and because it's simple and easy.

Better than poison

Poison works in one respect: it kills any animal that eats it. Your problems start afterwards. Rats and mice live in the walls and under the floors of our homes and offices. They're small and very nimble - they can climb into the tiniest hole to make a nest. This is quite likely to be the place where a poisoned animal will die, and where the corpse will decompose.

And trust us: you have not encountered a bad smell until you've encountered decomposing vermin. The stink is awful, and there's very little you can do about it. Even if you have a rough idea of where the nest is, you'd have to pull up floorboards or open holes in walls to make a hole large enough for you to gain access to deal with it; and what you'd find would be extremely unpleasant.

The only thing you can do is hope for good weather, because then you can at least open all the windows wide and hope the wind blows the smell away.

Better than traps

Rat and mouse traps come in all sorts of shapes and sizes, some more reliable than others. Entice the vermin with some suitable bait (almost anything will do, but chocolate and chewy sweets are a good choice, as well as the more traditional cheese) and sooner or later you might end up with a catch. (Watch out, though - some vermin are smart enough to get the bait off the trap without being caught!)

The problem with traps is that you still have a rat or a mouse to dispose of; with glue traps, this rodent is alive! Standard traps leave you with a corpse, which you mustn't touch because of the threat of disease. Humane traps give you a different headache: a wriggling, terrified, hungry and possibly very annoyed rat or mouse to get rid of. And it's no good just letting him out in the back garden, because he'll be back inside your house in minutes.

What's more, traps are a burden on your time. They need to be constantly checked, re-baited, and checked again. If you've placed them in loft spaces or dark corners, this soon becomes irritating.

Better than ultrasonic pest control

Most people have heard of ultrasonic pest control devices. Unfortunately, not many people know that they are just not effective.

Pest control experts were discussing this as long ago as the early 1980s. Studies performed then showed that while ultrasound might trouble vermin for a few minutes, perhaps even a day or so, to begin with, it was not a long-term solution.

The pests just get used to the new sound environment and carry on as before. They're not deterred and they're not dealt with.
