Cleanliness

Much can be done to check the ravages of insects by destroying their breeding-places and hiding-places. Weeds, rubbish, and refuse should be eliminated.

Hand-picking is often still the best means of destroying insects despite all the perfection of machinery and of materials. This is, particularly true about the home grounds and in the garden. The cultivator should not scorn this method.

Promoting Growth

Any course that tends to promote vigor will be helpful in enabling plants to withstand the attacks of plant-lice and other insects.

Burning

Larvae which live or feed in webs, like the tent-caterpillar and fall web-worm may be burned with a torch. The lamp or torch used in campaign parades finds its most efficient use here.

Banding

To prevent the ascent of canker-worm moths and gypsy-moth caterpillars, various forms of sticky bands are in use. For this purpose there is no better substance than "tree tanglefoot." It may be applied directly to the tree-trunk, but when so used leaves an unsightly mark and requires more material than when the following method is used: First place a strip of cotton batting 3 inches wide around the trunk; cover this with a strip of tarred paper 5 inches wide; draw the paper tight and fasten at the lap only with three or four tacks. Spread the tanglefoot on the upper two-thirds of the paper, and comb it from time to time to keep the surface sticky. Burlap bands are made by tying or tacking a strip of burlap around the trunk and letting the edges hang down. The larvae will hide under the loose edge, where they may be killed. Banding is now little used for codlin-moth, since spraying with poison has been found so much more effective.
