Late October
Here’s what’s bothering Delaware homeowners in late October. Find yours, then call for help or snap a photo.
Rated Peak for October on our pest season calendar.
They’ve been piling onto sunny south- and west-facing walls since September, and now they’re slipping in around windows and siding. Vacuum them up instead of crushing them.

Stink bug guide →Black-and-red bugs gather on sunny walls, porches and window frames in October, looking for cracks to spend the winter. They don’t bite, but squashed ones can stain fabric.
Boxelder bugs inside? Call The Bug Guy 302-242-5254 Mosquito & Pest Authority 302-346-2970
Boxelder bug guide →Orange, spotted beetles cluster on sunny walls and windows in October and crawl into gaps to overwinter. Vacuum them instead of crushing them: crushed beetles stain and smell.
Beetles all over your windows? Call The Bug Guy 302-242-5254 Mosquito & Pest Authority 302-346-2970
Lady beetle guide →Cold nights push mice from the fields and woods into houses, garages and outbuildings, and a mouse can fit through a hole the size of a dime. Scratching in the walls, droppings and gnawed packaging are the first signs.
Hearing scratching? Call The Bug Guy 302-242-5254 Mosquito & Pest Authority 302-346-2970
Mice & rats guide →October is the end of spider season, and many follow other insects indoors. Most are harmless, but black widows turn up in woodpiles, sheds and crawl spaces.
Not sure which spider? Snap a photo or call The Bug Guy 302-242-5254 Mosquito & Pest Authority 302-346-2970
Spider guide →Adult deer (blacklegged) ticks are most active in late fall and winter, so ticks are still a risk after time in leaf litter and along wooded edges. Check yourself, kids and pets after time outdoors, and remove an attached tick with fine tweezers close to the skin.
Found a tick on you or a pet? Call The Bug Guy 302-242-5254 Mosquito & Pest Authority 302-346-2970
Tick guide →These five are rated Active, not Peak, on our calendar for October. They never really left.
German roaches live indoors all year and breed fast, so a few in the kitchen usually means more hiding in the cracks. Store-bought sprays often miss most of them.
Seeing roaches? Call The Bug Guy 302-242-5254 Mosquito & Pest Authority 302-346-2970
Cockroach guide →These humpbacked, wingless jumpers hide in damp basements, crawl spaces and garages. They don’t bite, and drying things out and sealing gaps usually fixes it.
Basement jumpers? Call The Bug Guy 302-242-5254 Mosquito & Pest Authority 302-346-2970
Camel cricket guide →These slow, dark-gray flies moved into attics and walls in late summer. They wake on warm days and gather at sunny windows. They don’t breed indoors, so vacuum them and seal the gaps they come out of.
Flies at your windows? Call The Bug Guy 302-242-5254 Mosquito & Pest Authority 302-346-2970
Cluster fly guide →They’re active all year, and they hitchhike in on luggage, clothes and used furniture. Rusty spots on mattress seams are a telltale sign, and a partial treatment can spread them.
Think it’s bed bugs? Call The Bug Guy 302-242-5254 Mosquito & Pest Authority 302-346-2970
Bed bug guide →Flea eggs and larvae in carpet and bedding keep hatching, even after you’ve treated your pet. Raccoons, opossums and feral cats under porches and decks can leave them behind.

Delaware pest control for termites, ants, rodents and wildlife across New Castle, Kent and Sussex counties.
1
Inspect
They walk the property and find the entry points, harborage and moisture that are actually driving the problem.
2
Identify
Correct species identification. The treatment for carpenter ants is not the treatment for odorous house ants.
3
Treat
Targeted application using the least-impact product that will do the job. Botanical options on request.
4
Monitor
They come back, check the stations and traps, and adjust. Pest pressure changes with the season.
