Mosquitoes, cockroaches, termites, rodents and ants all get worse from late June onwards. Here is what genuinely helps, what people waste money on, and how to prepare for a professional treatment.
From the last week of June until about the end of September, every house in Rohtas is running the same slow battle. The rain brings standing water, the damp gets into walls and furniture, food stores stay humid, and every pest that was managing quietly through the summer suddenly has everything it needs.
Most households respond by buying things — sprays, coils, chalk, gels, traps. Some of that helps. Much of it is money spent on the symptom while the cause sits untouched three feet away.
The principle that decides everything
Pests come for three things: water, food and shelter. Take away any one of them and the population drops on its own. Leave all three in place and no spray will hold for long, because you are killing the insects that are present while the conditions keep producing more.
That is why the first hour of pest work should be spent walking the house and the compound rather than spraying anything.
Mosquitoes and standing water
Mosquito control is almost entirely a water problem, and the water is usually within a few metres of the house.
- The saucers under potted plants, which refill every time it rains
- Old tyres, broken buckets, discarded containers and construction debris in the compound
- The cooler that has been switched off but not emptied
- Blocked roof drains and the flat bit of terrace that holds water after a shower
- Uncovered overhead tanks and open drums
- The gap between the boundary wall and the neighbouring plot where water collects
Emptying and drying these once a week does more than any spray, because the life cycle from egg to adult is short enough that weekly clearing breaks it. Beyond that, mesh on the windows and a net over the bed are the two things that reliably reduce bites indoors.
Fogging a compound looks dramatic and kills adult mosquitoes that are flying at that moment. It does nothing to the larvae. If the breeding water is still there, the numbers are back within days.
Cockroaches and drains
Cockroaches are a drain and a moisture problem. They come up through floor traps, gaps around waste pipes, and the space behind and under the kitchen platform, and they stay because there is water and food residue for them.
What helps
- Keeping the floor trap covered when not in use, and fitting a proper trap where there is only an open hole
- Sealing the gap where the waste pipe passes through the wall or floor
- Cleaning behind and under the fridge, the gas stove and the platform, where the grease and crumbs actually are
- Not leaving the sink wet overnight, and not leaving utensils soaking
- Gel baits placed in cracks and hinges rather than sprayed on open surfaces
What usually does not
Spraying an aerosol along open skirting when the colony lives inside the drain and the cabinet voids. It clears the ones you can see and leaves the source alone. Chalk lines drawn across a floor are the same idea and have the same limitation.
Termites in damp walls and furniture
Termites are the expensive one, because by the time they are visible the damage has been running for a while. In our conditions they get into the house through the plinth, through wall damp on a shared or north-facing wall, and through wood in contact with the floor.
The signs to look for during and just after the rains:
- Thin mud tubes running up a plinth, a wall or the back of an almirah
- Paint or a wall surface that bubbles slightly and sounds hollow when tapped
- Door frames and skirting that feel soft or give way under a fingernail
- Fine soil-coloured debris near a wooden joint
- Winged insects swarming for a short while after a heavy shower, then shedding wings near a window
A wooden almirah pushed flat against a damp wall is the classic starting point. So is a cupboard standing directly on the floor in a ground-floor room with rising damp.
Please do not do this: never break open a termite tube and spray a household insecticide into it. It scatters the colony into the wall, makes the infestation harder to locate and treat properly, and does not kill the nest. Leave the tube intact and let the technician see it exactly where it is.
Professional termite work is a structured treatment of the soil, the plinth and the affected woodwork, not a spray round the skirting. It is a different kind of job from a general pest treatment, and it should be quoted and explained as such. The various treatment types are described on our services page and the current charges are on the rate list.
Rodents and ants
Rats follow a route
Rats move indoors when their outside runs flood. They are following a route, and the route is usually obvious once you look: a gap under a door, a hole around a pipe, a broken ventilator mesh, a drain cover missing, an overgrown patch next to the wall.
Blocking those entry points with steel wool and cement holds far better than any trap, because a trap deals with one animal and a sealed gap deals with all of them. Store grain and dry food in metal or thick plastic with tight lids rather than in sacks on the floor, and keep the area behind stored furniture clear.
Glue boards are widely sold and widely regretted. They are slow, unpleasant to deal with, and they catch lizards and birds too.
Ants follow a trail
Ants are mostly a nuisance rather than a risk. They come in along a defined trail toward a specific food source, and wiping the trail with soapy water removes the chemical marker they follow. Sealing food, fixing the slow leak under the sink and clearing the sweet residue usually ends it. If a large black ant is appearing from a damp window frame rather than from outside, that is worth showing someone, because it can indicate wood damp enough to matter.
Preparing for a professional treatment
The treatment works better if the house is ready for it:
- Clear the kitchen platform and empty the lower cabinets so the technician can reach the corners and voids.
- Move furniture a little away from the walls.
- Cover or put away exposed food, drinking water, utensils and pet bowls.
- Take pets, fish tanks and birds out of the treated area, and cover an aquarium and switch off its air pump if it cannot be moved.
- Tell the technician in advance if there is an infant, an elderly person with a breathing condition, or a pregnant woman in the house. This changes how and when the work is done, and it is information they need before they arrive, not after.
After the treatment
Stay out of the treated area for as long as the technician tells you, and then ventilate before moving back in. Do not mop the treated skirting and corners immediately, because washing off the residue is washing off the treatment.
Expect to see more cockroaches for the first few days, not fewer. They come out of the voids as the treatment takes effect. That is the treatment working, not failing. Any follow-up visit should be discussed and agreed before the first visit, so you know what is included.
Timing and coverage
The best time for preventive work is just before the monsoon, in June. The next best is now — through and immediately after the rains, when the damp has peaked but before everything moves indoors for winter.
We handle pest control across Sasaram, Dehri-on-Sone, Nokha, Kudra and Bhabhua, with the full list on the service areas page. A bill is given for every job, and the technician will tell you what has been used and what precautions apply before starting.
Frequently asked questions
Damp is the main reason. Drains stay wet, floor traps hold water, and the voids behind kitchen cabinets and under the platform stay humid, which is exactly what cockroaches need to breed. They come up through drains and gaps around waste pipes. Sealing those gaps and keeping the sink dry overnight matters more than spraying.
Look for thin mud tubes on the plinth, walls or behind an almirah, paint that bubbles and sounds hollow when tapped, door frames or skirting that feel soft under a fingernail, and fine soil-coloured debris near wooden joints. Winged insects swarming after heavy rain and shedding wings near windows is another common sign.
It can be, provided the household is prepared and the technician is told in advance. Say beforehand if there is an infant, a pregnant woman, an elderly person with a breathing condition, or pets, because it changes how and when the work is done. Move pets and birds out, cover aquariums, and stay out of the treated area for as long as the technician specifies.
Only briefly. Fogging kills adult mosquitoes flying at that moment but does nothing to the larvae in standing water. If the breeding sites remain, numbers return within days. Emptying plant saucers, coolers, tyres, drums and blocked roof drains once a week breaks the breeding cycle, which is what actually reduces mosquitoes.
