David Larkin sent photographs of a garden spider (above), one of which he took through the web, showing its underside, which had markings quite different from its topside.

I have two nesting boxes in the garden, yet neither of them has ever been used. I have moved them away from the feeding tray, but still to no avail. Billy Byrne, Dundalk, Co Louth

Nest boxes should not be placed in direct sunlight (preferably facing north through east) and should be sheltered from prevailing winds in some cover. Otherwise it is a matter of luck if birds may choose them.

I noticed that the playground in Bushy Park in Terenure is ring-fenced by dark green Rentokil boxes. Surely rodent- control measures like this can have a knock-on effect on wildlife in the park. Róisín Sheerin, Harold's Cross, Dublin

Pest-control companies are required to adhere to certain rules in public places.
