Garden Pests Control – When to Spray With Pesticides

New Aphids up close

When spraying pesticides for garden pests, few gardeners realize the close connection between temperatures and the
appearance of garden pests.

It would seem that Mother Nature likes to play the game of the Tortoise and the Hare.

She gives the garden pests a head start, gives the gardener a chance with his spray gun and pesticide spray, then turns the predators loose with the hope that they can over-take the pests.

Predators are insects that feed on other insects (natural pest control).

Garden Pest Hatching At 50

The garden pests – the aphid – is a concrete example of how insect pests operate. Aphids start hatching when the average temperature reaches 50 degrees.

The lady bugs, aphid lions and other aphid enemies don’t start hatching until the average temperature reaches 60 degrees, which is ten days or two weeks later. This ten-day interval is of prime importance to the gardener. (psst… It’s time to apply pesticides for aphids control)

Watch And Spray

The wise gardener watches for the first aphids and sprays a pesticide immediately even if there are only a few garden pests.

If the big increase is thus headed off, the aphids are held in check until the predators can marshal their forces and do the clean-up job.

Aphids hatch and multiply rapidly.

If left alone, by the time the predators start action, the pests are so far ahead they cannot catch up. That is when the average gardener starts to spray and kills both good and bad insects.

Take Advantage and Save The Damage

The informed gardener doesn’t wait until the garden is full of pests. You can take advantage of the ten-day interval between the coming of the pests and the predators and beginning a garden pest control spray program.

By so doing, you can save a lot of damage to your garden and save a lot of insecticides and spraying later on. If the aphids are held in check until the predators get going, they can maintain an even balance.

There will be no further need of spraying and the helpful insects won’t be destroyed along with the pests.


Get out the old notebook and record the first appearances of your garden enemies. It will be something like ten days before their predators appear (if you haven’t killed them out entirely).

By recording dates, you can know the approximate time to spray any insecticides/pesticides. There will be some variance in seasons.

Watch the temperature averages and be on the alert to find the first insects to appear. Have your spray gun ready and help the predators keep your garden free of insects.
