Firgrove is a small, quiet spot on the Somerset West side of the Helderberg, with a country feel and a lot of open land around it. People here mostly call us about mice from the fields, flies around animals and wasps in the sheds.
Firgrove: what drives flying insects here
Flies around horses, poultry and compost are a summer issue, and paper wasps build in sheds, carports and under eaves.
Farmland and vineyards surround the area, with the Helderberg and the Hottentots Holland mountains on the skyline. The South-Easter blows strongly through summer, and winters are wet and chilly. When fields are ploughed or harvested, the rodents living in them look for new homes.
Field mice and rats looking for shelter are the main call, especially after harvest and in winter. Flies around livestock and paper wasps in sheds follow in summer, and homes on the edge of open land see more spiders and the odd scorpion.
How to tell you have a problem
- Flies keep gathering around the same window, light or rubbish area even after you have cleaned and sprayed.
- Small flies hover over the fruit bowl, the recycling bin or the drip tray under a bar tap.
- Tiny moth-like flies sit on bathroom walls near the shower or basin drain.
- Small moths flutter out of the pantry or out of a cupboard full of woollens.
- Paper wasps are coming and going from the same spot under the eaves, a gutter or a garden umbrella.
- A sudden swarm of large blowflies appears indoors, which often points to something dead in the roof or wall.
Something most people miss
The first thing a technician checks is not the fly but the place it keeps landing. Where an insect rests tells us a lot about where it came from and which treatment will reach it.
Buzzing bug zappers in a kitchen can do more harm than good, because they can scatter insect fragments around. Glue board light traps are the better choice anywhere near food.
Our process, step by step
We start by identifying the insect properly, because a drain fly needs a completely different fix from a house fly or a mosquito. Breeding sites come first: drains are cleaned out and treated with a larvicide or bio-enzyme product, standing water is tipped or treated, and waste areas are sorted out. Only then do we use residual sprays on resting surfaces such as window frames and wall tops, fly bait stations away from food, and ULV fogging where a large space needs a quick knockdown. In commercial kitchens and food stores we install insect light traps with glue boards so there is constant monitoring between visits. Wasp nests are treated with a dust or spray directly into the nest and removed once the colony is dead.

Keeping them out afterwards
- Keep wheelie bins closed, rinse them out in summer, and park them away from the kitchen door.
- Check eaves, carports and garden furniture in early spring for small paper wasp nests while they are still easy to deal with.
- Pour boiling water down slow drains weekly and scrub the inside of the drain pipe with a brush, since that slime is where drain flies breed.
- Tip out pot plant saucers, birdbaths and anything else that holds water for more than a few days.
- Fit fly screens on kitchen windows and keep a self-closing door or strip curtain on back doors that open onto bins.
Pricing, honestly
The price depends on which insect we are treating, because a single wasp nest is a very different job from a fly problem in a large food factory. The size of the property, how many breeding sites there are and how hard they are to get at, such as roof voids or sealed drains, all affect the time on site. Commercial sites with light traps and scheduled visits are usually best quoted as a contract, and we give free quotes once we know what is flying.
Fly swatters, screens and a good bin routine handle a lot of household fly problems, and we would rather you did that than empty a can of spray into the kitchen. Where DIY falls down is when the source is hidden, like a dead rat in the ceiling, a broken drain under the floor or a wasp nest in a wall cavity. If you are still seeing the same insects two weeks after cleaning up, the breeding site is somewhere you have not found yet.
Questions we get asked in Firgrove
Do insect light traps actually work?
Yes, in the right place. They catch flies that get past your doors and screens and, just as usefully, the glue boards show us what is getting in and how many, which is why food businesses rely on them.
Do you service smallholdings and outbuildings in Firgrove?
Yes. We cover the house, sheds, stables and feed stores, and we plan bait placement so it stays out of reach of pets and livestock.
What are the tiny flies around my bathroom drain?
They are almost always drain flies, also called moth flies. They breed in the gel-like film inside drains, so cleaning the pipe properly works far better than spraying the walls.
How quickly can you come out?
We aim for around 48 hours, though it varies with the season, and we can do after-hours or weekend visits on request.
Do you come out to Firgrove for flying insect control?
Yes. Firgrove is part of our regular Helderberg route, along with Somerset West, Macassar, Strand, Helderberg. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Why are there suddenly mice in my Firgrove house in autumn?
Cooler weather and work on the surrounding fields push mice toward warm, sheltered buildings. Sealing gaps under doors and around pipes early in autumn keeps most of them out.
