Diwali Pest Control in Kolkata: How to Keep Your Home Pest-Free Before Kali Puja
Diwali and Kali Puja are a special time in Kolkata. Homes are cleaned from top to bottom, cupboards are opened, furniture is moved, diyas and lights are put up, and families prepare to welcome guests. But there is one little problem that often appears alongside all that festive preparation: pests. The combination of Kolkata’s post-monsoon weather, stored household items being moved around, food preparation and bright evening lights can bring cockroaches, mosquitoes, ants, silverfish, spiders, lizards and flying insects into the open. During Kali Puja, many homes also notice swarms of small flying insects around bright lights, locally referred to as Shyamapoka.
The good news is that a little preparation before the festival can make a big difference.

Why Do Pests Increase Around Diwali in Kolkata?
Kolkata’s pest activity changes with the seasons.
The monsoon leaves behind humidity, damp areas and standing water, which can support mosquitoes and cockroach activity. As October arrives and the weather starts becoming slightly cooler, some pests look for warmer, sheltered places inside homes. Then comes Diwali and Kali Puja. Festival lights can attract night-flying insects, while deep cleaning can disturb pests that have been hiding in cupboards, storerooms, furniture and dark corners.
So, if you suddenly discover a few unwanted guests while preparing your home for Puja, you’re definitely not alone.
Common Pests You May Notice Before Kali Puja

Some of the most common pests around Kolkata homes during this period include:
- Cockroaches – particularly around kitchens, sinks, drains and cabinets
- Mosquitoes – especially where stagnant water is present
- Ants – attracted by sweets, sugar and food particles
- Silverfish – often found in cupboards, books, cardboard and damp storage areas
- Bed bugs – potentially disturbed when old bedding or stored furniture is moved
- Spiders – commonly found in quiet corners and storerooms
- Lizards – attracted to homes where flying insects are abundant
- Rodents – particularly around storerooms, kitchens and food-storage areas
- Flying insects or “Shyamapoka” – often noticed around bright festival lights
Not every insect that appears during Diwali requires professional treatment. Sometimes the simplest changes to lighting, cleaning and food storage can reduce the problem considerably.
1. Start Your Diwali Cleaning Early
Don’t leave the entire cleaning process to the day before Kali Puja.
When you move furniture, open old boxes or empty cupboards, you may disturb pests that have been hiding there for weeks or months.
Pay particular attention to:
- Kitchen cabinets
- Under sinks
- Behind refrigerators
- Storerooms
- Areas underneath beds
- Cupboards containing old clothes
- Bookshelves
- Cardboard boxes
- Bathroom corners
- Balcony storage areas
Ensure that you vacuum and/or sweep these areas thoroughly and remove any unwanted paper/cardboard and packaging. If you see any live cockroaches, bedbugs, signs of termites or an excessive amount of insects whilst cleaning, don’t just put everything back and seal it up. Firstly identify what the problem is and if you require further treatment.
2. Be Careful With Diwali and Kali Puja Lights
One of the most prominent issues that you will encounter when it comes to pests during Kali Puja is flying insects appearing out of nowhere. Many nocturnal flying insects can be attracted to bright white lights. An easy solution is to use warm or yellow lighting wherever possible, especially near to your balconies, windows and outside areas.
You can also:
- Turn off unnecessary outdoor lights after use
- Keep windows and doors closed where possible
- Repair damaged window screens
- Avoid placing extremely bright lights directly beside open windows
- Keep vegetation around entrances trimmed
You don’t have to turn your home into a dark cave for Kali Puja. The idea is simply to reduce unnecessary light that attracts insects directly toward your doors and windows.
3. Keep Sweets and Food Properly Covered
During Diwali and Kali Puja there is a lot of sweet and snack eating. Unfortunately these are loved by cockroaches and ants! Store all sweet and food items in sealed containers. Clean up any spillages of sugar or food as soon as possible and do not leave dirty dishes in the kitchen for long periods of time.
Also remember to clean around:
- Gas stoves
- Kitchen counters
- Dining tables
- Refrigerator areas
- Sweet boxes
- Pet-food bowls
- Dustbins
A tiny amount of food residue can be enough to attract ants and cockroaches.
4. Try Simple Bengali Home Remedies for Minor Insect Problems
Many families in Kolkata use natural remedies. For instance, neem leaves are a popular natural way to keep your home free from insects. Some people will even place diluted peppermint, eucalyptus or lavender oils around windows and doors. Strong smells can put some insects off.
You could try placing neem leaves in the right corners or use an essential oil spray with diluted oil around your entrances. It is important to know that this is not completely effective though. Home remedies may help repel or reduce occasional insects, but they are not a reliable replacement for treatment when there is an established infestation.
For example, a few ants near a window are very different from a persistent cockroach infestation inside kitchen cabinets.
5. Check for Mosquito Breeding Areas
Although mosquito activity is often associated with the monsoon, Kolkata can still have mosquito problems during October.
Before Kali Puja, inspect your home and surroundings for stagnant water.
Check:
- Flower pots and trays
- Buckets
- Roof areas
- Drains
- Water containers
- Unused outdoor items
- Balcony corners
Ensure any stagnant water is emptied regularly and cover containers where possible. This is especially important as not only will it help prevent mosquitoes biting but will also reduce the breeding grounds of mosquitoes.
6. Don’t Ignore Your Storeroom
The storage room is often an overlooked area. Unused clothes, old newspapers, card boxes, furniture and seldom used cupboards can make a perfect hiding place for several pests found in the house.
Before Diwali:
- Remove unnecessary items.
- Check boxes before moving them indoors.
- Clean behind stored furniture.
- Inspect old bedding.
- Look for droppings, shed insect skins or live insects.
- Keep storage areas dry and reasonably ventilated.
This is also a good opportunity to spot an infestation before it spreads further.
When Should You Book Pest Control Before Diwali?
If you already have a noticeable pest problem, don’t wait until the day before Kali Puja. For a planned pre-Diwali treatment, around 2–3 weeks before the festival gives you useful time to complete cleaning, treatment and any necessary follow-up.
A practical sequence is:
Deep cleaning → pest inspection/treatment → allow treatment to work → final cleaning → Puja preparation
If you are dealing with a serious infestation such as bed bugs, termites or a persistent cockroach problem, the timing may need to be adjusted according to the pest and treatment method.
How Much Does Pest Control Cost in Kolkata?
The price depends on the pest, property size, infestation level and treatment required. There isn’t one fixed price for every home.
As a general Kolkata reference, typical starting ranges are:
| Pest Control Service | Approximate Price in Kolkata |
|---|---|
| Basic / General Pest Control | ₹500–₹600+ |
| Cockroach Control | ₹600–₹1,500+ |
| Termite Treatment | ₹2,000–₹10,000+ |
| Bed Bug Treatment | Depends on property and infestation |
| Rodent Control | Depends on property and infestation |
The following are approximate costs, it may take extra treatment for larger homes or a more severe infestation. Ask your Diwali pest control service what treatments are included in the quotation, if there is any aftercare and if there is any warranty provided.

Is Pest Control Safe Before Diwali?
Yes if used properly and following the manufacturers safety guidelines. In some cases professional Pest Control treatments will use a spot-on gel or bait or spray specific to the pest and location. For example, using spot-on gel can be better than spraying unnecessarily in kitchens.
Before treatment, tell the technician about:
- Children in the home
- Pets
- Aquariums
- Food-storage areas
- Elderly family members
- Any sensitive areas
Follow the required re-entry and ventilation instructions after treatment. Don’t assume that a product is safe simply because it is described as “natural” or “eco-friendly.” Always follow the product label and professional instructions.
What About Shyamapoka Around Kali Puja Lights?
If you notice hundreds of tiny flying insects gathering around your lights during Kali Puja, the lighting itself may be contributing to the problem.
Rather than spraying insects randomly, start by reducing the attraction:
- Use warmer or yellow-toned lights where suitable.
- Keep unnecessary lights switched off.
- Close nearby windows and doors.
- Use window screens.
- Clean insects that have already entered.
- Reduce outdoor vegetation immediately beside entrances.
If flying insects are repeatedly entering the house in large numbers, check whether there is another source of attraction or entry point.
A Simple Pre-Diwali Pest Checklist for Kolkata Homes

Bedrooms
- Check stored bedding

Should You Use Home Remedies or Professional Pest Control?
It depends on the problem.
For occasional insects, improving cleanliness, removing standing water, using screens and reducing light attraction may be enough.
But professional treatment becomes more appropriate when you are dealing with:
- Repeated cockroach sightings
- Bed bugs
- Termites
- A persistent rodent problem

The goal isn’t to spray every insect you see. It is to identify why the pests are present and address the source.
