Spell Bee Word: insecticide


Basic Details

Word: Insecticide

Part of Speech: Noun

Meaning: A chemical used to kill insects such as mosquitoes, cockroaches or pests that eat crops.

Synonyms: pesticide, bug spray

How to Spell Insecticide

Syllables: in - sec - ti - cide

Tricky part: Insect is joined to cide by an i, and cide is spelt with a c, not an s. Insectiside and insectcide are both common slips.

Watch out for: insectiside, insectcide, insecticid, insectaside

Memory tip: Cide at the end means killing, as in pesticide and germicide. So: insect + i + cide, a killer of insects.

Usage Examples

Example 1: Mummy sprayed insecticide in the corners of the kitchen to get rid of cockroaches.

Example 2: Some farmers in Punjab now use neem oil instead of a strong insecticide.

Example 3: Keep the insecticide can on a high shelf where small children cannot reach it.

Fun Fact

The neem tree, common across India, contains a natural chemical called azadirachtin that stops many insects from feeding and growing.
