Learning more about snakes is likely to reduce your fear of them, understanding what they do, where they go and why tends to help (it certainly did with my fear of moths and stopped a fear of spiders forming in its tracks!)..
We have three native species and 1 non-native that appears to be capable of surviving here - however:
- Smooth snakes - so rare that the people who want to see them and actively look for them struggle to get wild sightings!
- Adders - very small and dark, again not a snake you're liable to come across unless you walk on sunny moorlands for hours every day.
- Grass snakes - can get to 6ft, however they actively want to stick to ponds (not so much large lakes) and warm damp places like muckheaps with an abundance of mice/rats/frogs etc. They do not want to leave these preferred environments to come to your house, your house is a horrible dry barren place for them with no food.
- Aesculepian snakes - these are non-native european snakes. There are three colonies in the UK - Colwyn Bay and Brigend in Wales and a tiny area of Regents Canal in London. Again you're not going to find these snakes even if you went looking for them!
Snakes really really want to be left alone. Only the Adder is venomous and that can be treated easily. The others are constrictors and you're only in danger if you're a frog or a mouse which I suspect you are not.
They hide from us, they want to avoid us, they do not want to come into our homes and really are NOT found in our homes with any significant regularity (I am not aware of any cases of our native snakes being found inside peoples homes!). If you have a garden that has a lot of cover and a pond you may get grass snakes - they really will not come inside. They want to stay out and eat any mice/rats/frogs etc that they find out there. They are very much doing you a favour!
We only tend to see snakes if we're sitting in the right place outside being very very quiet, then you may if you're extremely lucky, catch one about its business or sunbathing. In 40 years of looking for snakes (I started young!) I have seen:
2 Grass snakes
2 Adders.
1 Slow Worm (not a snake, a lizard without legs).
Thats with me actively going to places they will be and seeking them out.
If you want to reduce the chances of seeing them on your own property - don't have a pond, don't have a muck heap - keep rodents down - keep lawns mowed short. Stomp around and make a lot of noise when gardening.
