BT Organic Insect Control for Your Tomatoes


Kill Bad Bugs Using Natural Methods

How would you like to kill bugs BEFORE they have a chance to kill your plants?

If that sounds good to you, keep reading because we’ve got exactly what you’re looking for.

BT is an organic insecticide that uses the natural pathogenic bacteria, bacillus thuringiensis (thus the BT) to kill insects before they’re big enough to eat your plants. The insect consumes it and the BT cells germinate inside the insect or caterpillar causing death within a few days.

The pest first stops feeding, then drops to the ground and decays without causing any harm to the environment, people or any non-target species. The best time to apply BT is after eggs have hatched and the caterpillars are very small. Larger caterpillars like the dreaded tomato hornworm must be sprayed with the product for it to work.

If you see these full-grown bugs, it is best to hand pick them off of your plants. Because it is an environmentally sensitive control, BT might be just the thing you are looking for to keep pests away from your tomatoes.
