Answer 1

From your description, these sound like Fall webworms which may be controlled without using insecticides by thoroughly inspecting trees that have a history of severe infestations for new webs or egg masses. Webs can be pruned out and destroyed. To be effective, gardeners must be committed to continually inspecting trees for new webs and/or egg masses.

If webs become too numerous or are out of reach for pruning, then insecticides may be needed. One of the safest on the market are those containing Bacillus thuringensis, a bacterial derivative that is effective only on caterpillars; it doesn't harm beneficial insects needed to keep other pest populations down. The toxins produced by the bacteria are ingested by the larvae and destroy the digestive tract of the caterpillar. The product, commonly called B.t. is marketed under the tradenames of Dipel, Thuricide, Bactur, or Bioworm. It is safe to use on fruit and nut trees .

B.t. products are also effective on other caterpillars including cabbage loopers, armyworms, and tussock moth caterpillars.

Other chemicals available for fruit and nut crops include carbamyl (Sevin) and malathion. Ornamental trees can be sprayed with acephate (Orthene) or diazanon. Be forewarned that diazanon is no longer labeled for use on pecan trees and is going to be off the market for all home landscape use in a couple of years.

Complete coverage is needed for good control. A high-pressure sprayer may be necessary to reach the tops of trees or to penetrate dense webs. Breaking up the webs with long poles prior to spraying may increase contact of the insecticides with the larvae and increase effectiveness. It may be necessary to use a commercial tree spraying service for large trees or heavy infestations.

Early recognition and control is the key to minimizing damage from fall webworms. So if webs start appearing in your trees, don't put off control measures. Attack those webworms quickly and reduce your frustrations before they get out of hand. This early line of defense will help you win the war against fall webworms.

Good luck - I had an infestation several years ago and it took a couple of applications of diazinon to kill them completely, but the trees eventually recovered and are doing well now.

Answer 2

Has your area been rainy lately? Sometimes spider webs can be a sign of webworms that love to live on trees. They require spraying with a chemical. Again, read labels on chemical at the store or call a pest control man. Webworm are horrible little caterpiller looking things that will eat leaves like a maniac. Best luck

Answer 3

They are called web-worms. They overwinter in the ground and reinfect your trees the next year if you don't get rid of them. Go to your local garden store and ask for a chemical to treat web-worms. You will have to tear the webs open to get to the worms because the webs are so close that the spray won't get into them otherwise.

Answer 4

Sounds like web worms. Dust with sevin dust or other available vegetable dust, or even safer, spray with dish washing detergent such as dawn, mixed in water. Hose end sprayer will work fine, if up high you may need a trombone sprayer.

Answer 5

tentworms or bagworms. I don't recommend the old-fashioned method of burning them off. There are insecticides you can buy to spray them. Most are concentrates and require the purchase of a pump sprayer (and a ladder) to apply. You may want to call in an exterminator to deal with them.

Answer 6

I know what you are talking about but I can't remember what they are called but you need to get them out of your tree's fast!! The bugs feed off of the tree and eventually kill it call your local bug killer and ask them what they recomend
Good Luck!

Answer 7

it sounds like you have moth's . they will create a silk like nest in trees to lay their eggs ,when the eggs hatch they will eat the leaves. my advice is to cut the limb from the tree and burn it. I HAVE SEEN MANY TREES KILLED DUE TO THE CATERPILLAR STAGE

Answer 8

Hose it down. If you don't like using chemicals use pure soap.
