Why am I getting caterpillars in my house? Caterpillars can come in your house as guests on plants you bring inside or by creeping in through holes in screens, open windows or cracks in the walls. While these pests aren’t dangerous to you, they’re unsightly and unsanitary. Caterpillars come in a wide range of colors and may feel smooth or hairy.
What naturally kills caterpillars? Neem oil (oil pressed from neem fruit) is a potent insecticide and insect repellent. Dilute 2 ounces (3 centiliters) of neem oil in a gallon of lukewarm water (4 liters). Spray in the evening. Neem oil will suffocate the caterpillars and they will die off within hours.
How do you get rid of a caterpillar infestation? To treat against caterpillars, you can spray any plants, trees, and shrubs that the caterpillars eat with either Bonide Thuricide or Dipel Pro. Both products contain a non-toxic bacteria called Bacillus thuringiensis that destroys the stomach lining of the caterpillars.
How do I get rid of caterpillars fast? Removal by hand is really the most effective and simplest way to get rid of caterpillars quickly. Put on some well-fitting gloves, and drop the caterpillars into a bucket of soapy water. You can also try relocating them, as caterpillars don’t like to travel very far from their birthplace in search of food.
