High temperatures

Increased food source

Summer is a season when most foods are readily available. “One Saturday morning during summer, I noticed an increased number of rodents around my house” said local Susie Watts and happy customer of our Gold Coast pest control services. “This was due to the long healthy grass that had grown in my lawn, having not mowed it for a couple of weeks.” This shows that an increase in food supply leads to increased pest population. With summer showers pouring now and then, food is bound to be in plenty, and this helps sustain a large number of pests.

Having increased food cans means you are bound to be swimming in profit but can also turn into a period of loss as most pests like the rodents are also attracted by plenty of stored foods.

Longer daylight

This gives pest more feeding periods leading to their rapid increase in population. Only a small fraction of pests are active at night and so the majority of them prefer daytime.
