Food & HabitatSlide4

Moist Soil –

W

e will only water when the plants are bone dry

Rich Soil –

We will add sand to the soil before planting

Eating Dead Leaves –

We will remove all dead leaves from plants and from the soil

Eating Roots –

We will put potato pieces on the soil, and change them every 2 or 3 days

Adults –

We are using glue strips to trap and kill them

It is very safe

for people!
