Why Are Wasps Flying Into Your Dode Home? Common Causes and Solutions
Extractor outlets and cooker hood ducts are warm and smell of food, and a damaged flap or grille can let wasps straight into the kitchen.
The vent that smells of dinner
The outlet from your cooker hood or extractor fan carries warm air laden with cooking smells. To a wasp, that can be an irresistible signal. If the flap is stuck, the grille is damaged or the duct has a gap, the wasp can walk straight in.
The same is true for tumble dryer vents, boiler flues and bathroom fans, though kitchen extractors are the most common. Wasps may even build inside a duct or in the wall cavity beside it, since it is warm and sheltered.
For a household in Dode, wasps arriving in the kitchen without a window open are worth tracing to the vent.
Other openings behave in the same way. A tumble dryer vent that smells of warm laundry, a boiler flue with a loose cover and a bathroom fan that carries steam can all attract insects. Fit well-made covers to all of them, and check them once a season, especially before the warmer months.
Checking your ducts and flaps
Look at the outside wall where the outlet is. A healthy vent has a flap or louvre that closes under its own weight, and a grille with no broken slats. Check for:
- A flap that hangs open or is jammed.
- A grille that is broken, bent or missing.
- Gaps between the vent plate and the wall.
- Bird or insect debris round the opening.
- Wasps entering or leaving, which is the clearest evidence.
Do the check at a distance on a warm day, and watch for several minutes before approaching.
If the outlet is high up, do not climb a ladder to examine it while wasps are present. Use binoculars from the ground, or ask the technician to look at the height during the visit. A fall from a ladder is a far greater risk than the wasps, and wasps can be provoked by movement close to their entrance.
Inside the kitchen
Inside, notice whether wasps appear near the cooker hood, above the hob or around the extractor in the wall. A faint buzzing in the duct is a warning sign. Do not switch the fan on and off repeatedly to flush them out, which can stir up a nest, and do not take the hood apart to look.
Keep surfaces clean around the cooker. Grease and sweet spills give off smells that rise to the hood. Wipe the splashback, empty the bin and cover food while you cook.
If you cook a great deal, pay attention to the kitchen as a whole. Sticky pans, a food waste bin and a fruit bowl on the side all add to the smell. Wipe the hob and the splashback after every use, and empty the bin overnight so that the smells of the day do not hang around.
If you hear the buzz grow louder when the fan is switched on, switch it off, close the kitchen door and leave the room. Make a note of the date and time, as the technician will find this useful. Keep the extractor off until after the visit.
A fix for the flap
Once any wasp activity has been dealt with, replace a broken flap or grille. Many are inexpensive and can be changed by a competent person. Choose a design with a close-fitting flap or fine mesh. If the duct passes through a wall, make sure there are no gaps round it where wasps could pass.
Do not cover the vent while the fan is running or while wasps are present. Blocking a duct can create problems of its own, and it might push wasps into the kitchen. Wait for the technician and the all-clear.
When you choose a new extractor, look for a model with a built-in non-return flap that closes when the fan is off. Fit the outlet cover firmly to the wall, and seal the surrounding gap. Ask the installer how to keep it clear of dirt, which can jam the flap.
Safety around the kitchen
Keep children away from the hob area if wasps are emerging. If someone is stung, wash the area, remove the sting if it is visible and use a cold pack. A 999 call is needed for swelling of the face, lips or throat, wheezing or difficulty breathing, dizziness or a widespread rash. A person with a diagnosed allergy should speak to their GP.
A nest can hold from 2,000 to 10,000 or more wasps at its peak in August, so do not underestimate a build-up behind a vent.
Commercial kitchens have extra reasons to act, since customers, staff and food hygiene are all involved. Make a note of what you see and when, and report any wasp activity to the manager at once.
