1. First things first – what does natural pest control mean to you?
2. We all know ladybirds are good friends to have around the garden – but why ?
3. Which of these unlikely candidates helps to control slugs?
4. Why is the Tansy or Pyrethrum Daisy a useful plant to grow?
5. Fresh mint is said to be a deterrent for a common kind of pest; is it:
6. Phasmarhabditis hermaphrodita is a nematode worm used as biological control for a common garden pest – but which one?

10. If you’ve had a bad case of potato cyst eelworms, how long before you can safely plant potatoes again?
Answers.
1. It’s any of these and all of them – so one point for answering (a), (b) or (c) and give yourself a bonus point if you spotted this for the sneaky question it is!2. It’s (b); both adult and larval ladybirds eat huge numbers of aphids.
3. Answer (a). The Devil’s Coach-horse (also called the Devil’s Coachman or Footman) is a carnivorous predatory beetle that eats a range of invertebrates including slugs.
4. It’s (b) – the pyrethrum plant produces its own natural insecticide.
5. A few sprigs of fresh mint inside your cupboards or wrapped around any garden bulbs you’re storing is supposed to keep the mice away, so it’s (a).
6. Answer (c); this nematode is very specific and it only affects slugs.
7. Answer (a) – slugs and snails, though the beer trap idea might just work for some of the others too!
8. It’s (b), onions, chives and garlic. Garlic oil is a favourite with organic gardeners, while all three are said to be very useful when grown alongside other plants, keeping aphids and other pest species away.
9. Thrushes smash snail shells against an anvil stone to get at the soft bodies inside, so the answer’s (c).
10. Amazingly, it’s (c). In a really bad case of eelworms, you should leave the affected patch of ground potato-free for six or even seven years just to be sure there’s no more risk. Persistent little blighters, aren’t they?
