Synthetic Insecticides

Synthetic insecticides are manufactured at least in part using synthetic chemicals created from other chemicals. In many cases, they represent copies of a basic natural insecticde that have been improved in some way. The products that we describe here in Yardener's Tool Shed have been determined to be, in our judgement, effective in killing the specified insects while being safe to the ecosystem of the yard, safe for pets and children, and safe for the folks who use them.

Pyrethroids
A large percentage of the synthetic insecticides found in Yardener's Tool Shed are called "pyrethroids". Pyrethroids are synthetic materials designed to imitate natural pyrethrum which is derived from chrysanthemum flowers. These synthetic materials have the basic chemistry of pyrethrins but are modified to improve persistence and insecticidal activity.

Pyrethroid insecticides are contact and stomach acting and tend to be very broad-spectrum being active against a wide range of pest insects. Pyrethroids tend to be more effective than natural pyrethrins while they are less toxic to mammals. Pyrethroids have a number of varieties including permethrin, resmethrin, and deltamethrin.

Don't forget to check the "active ingredient" for each insecticide you buy.

Some Tricks For Success With Insecticides

Spreader Stickers can improve insecticide performance in many cases.

Insecticides are often more effective if applied using an additive called a \"spreader-sticker\" or "wetting agent" which helps the insecticide adhere better to the plants being sprayed, insuring improved performance of the material.

Cleaning The Sprayer
When you finish your spray job it is wise to use a commercial sprayer cleaner to be sure there is absolutely no residual insecticide when you again use that same sprayer for a different pesticide product.
