Hotter Summers Mean Longer Fly Seasons
Pakistan’s summers have been getting progressively hotter. In Lahore, June temperatures regularly touch 45 degrees Celsius. For most people this is uncomfortable. For house flies, it is ideal breeding weather.
House flies are cold-blooded. Their development rate from egg to adult is directly controlled by temperature.
Here is what that looks like in practice:
- At 20 degrees Celsius: egg to adult takes roughly three weeks
- At 35 degrees Celsius: under one week
- At 40 degrees and above: a new generation in approximately four days
In a Lahore summer, an untreated fly population does not stay stable. It compounds. A small problem in March becomes a serious infestation by May if nothing changes.
What This Means for Your Pest Program
The practical consequence of rising temperatures is that fly season now starts earlier and ends later than it did a decade ago.
In southern Punjab it effectively begins in February. In Lahore, by March. Businesses that base their pest control calendar on older assumptions and wait until flies are visibly present are already three to four weeks behind.
The right approach is to have ILTs deployed, waste management protocols running, and outdoor bait treatments in place before peak season, not during it.
The Breeding Source Problem Gets Worse in Heat
Higher temperatures also change how fast a neglected breeding source becomes a serious problem. A bin that is emptied every two to three days might have been manageable when development took three weeks. When development takes four days, that same bin is producing new adults faster than you are removing them.
Daily waste removal and fully sealed bins in a Pakistani summer are not excessive measures. They are the minimum for any facility handling food or serving customers.
One Maintenance Detail Most ILT Users Miss
Verminator’s Adhify ILT UV-A tubes need replacing every 12 months, even when the light output looks normal.
The attraction spectrum that draws insects to the unit degrades before the visible light output fades. A unit that looks operational may have lost most of its pulling power well before the tube visibly dims. Setting a fixed annual replacement date, regardless of appearance, keeps capture rates consistent through the peak summer window.
Getting Your Facility Ready
If your pest management program has not been reviewed recently, particularly with a longer and more intense fly season now the norm in Punjab, Nayab Pest Control Services provides free facility inspections and has been running IPM programs across Pakistan since the late 1990s.
